Summary The effects of different concentrations of calcium hydroxide [Ca(OH)2] and calcium lactate [C6H10O6Ca]
on the functional and physical properties of extruded (EF) and nixtamalised (NF) blue maize flours were
evaluated Calcium source and concentration showed no significant effects on the EF expansion index
The water absorption index (WAI) of EF decreased as the concentrations of both calcium sources
increased and NF with C6H10O6Ca had the lowest WAI The thermal and pasting properties of NFs were
higher than those of EF NF with C6H10O6Ca showed the highest final viscosity (FinV) indicating less
damage to the starch granules and this was correlated with microscopic analysis In contrast the FinV of
EFs was significantly affected by calcium source and concentration Extrusion with 03 and nixtamalisa-
tion at 295 of C6H10O6Ca yielded high WAI value and the best rheological properties in maize flour
respectively These results suggest the use of C6H10O6Ca in extrusion or nixtamalisation to produce blue
maize flours for tortilla or snacks with antioxidants
Keywords Blue maize calcium hydroxide calcium lactate extrusion nixtamalisation rheological properties
Introduction
Pigmented maize has received increased attention inthe last decade because of the consumer demand forhealthy nixtamalised corn products such as tortillasand tacos Anthocyanins give colour to the grains andare found mainly in the pericarp andor the aleuronelayer (Salinas-Moreno et al 1999) They have nutra-ceutical properties with possible health benefits (Leeet al 2005) During nixtamalisation the maize iscooked and steeped in calcium hydroxide [Ca(OH)2]solution to obtain nixtamal The pericarp is softenedand removed which allows calcium and water to dif-fuse into the grain causing physicochemical changes(Steffe amp Singh 1980) in starch protein and germthese changes affect the organoleptic properties of
masa (dough) flour tortillas and other nixtamalisedmaize products Blue maize nixtamalisation has thedrawback that with the removal of pericarp anthocya-nin and polyphenolic derivate compounds are also lostby leaching and instability at high pH values (Pflugfel-der et al 1988 Cortes-Gomez et al 2006) resultingin the varying colours of nixtamalised products Onthe other hand the extrusion cooking process has beenused to manufacture instant maize flour (Mensah-Agyapong amp Horner 1992 Gomez Aldapa et al1996) During this process the Ca(OH)2 addition isnecessary to provoke the physicochemical changes inthe starch to obtain flour masa and tortillas with simi-lar characteristics to nixtamalised maize flour besidesthat lime represents a calcium source to improve thenutritional products valueThe effects of lime during nixtamalisation and extru-

characteristics of blue maize flour have been reported(Cortes-Gomez et al 2005 Del Pozo-Insfran et al2007 Aguayo-Rojas et al 2012) However the use ofother calcium sources that generate less alkaline solu-tions for processing blue maize has not reported Pre-vious studies have shown that less alkaline conditionsdecrease the average molecular weight of starch with-out affecting the structural characteristics of the prod-uct (Kervinen et al 1984 Pan et al 1998) Thestructural characteristics of maize products have beenrelated to calciumndashstarch interaction during gelatinisa-tion studies and processing (Tovar et al 2004 Cortes-Gomez et al 2005) Robles et al (1988) and Mendezet al (2006) found that the calciumndashstarch interactionafter nixtamalisation causes an increase in the gelatini-sation temperature and enthalpy of starch Thechanges that are produced in the starch granules maybe evaluated through rheological functional and tex-tural properties of the final products (Robles et al1988 Mondragon et al 2004 Mendez et al 2006)The effect of alkalinity and calcium concentration onthe physicochemical and functional properties on theextruded and nixtamalised flour has been evaluated inprevious studies (Zazueta-Morales et al 2002 Mora-Rochın et al 2010 Aguayo-Rojas et al 2012)Although Ca(OH)2 has been used traditionally othercombined or individual compounds with or withoutcalcium have been studied in nixtamalisation (Robleset al 1988 Maya et al 2010) Ruiz-Gutierrez et al(2011) reported that white maize nixtamalisation withcalcium lactate [C6H10O6Ca] resulted in tortillas withgood colour and texture The use of C6H10O6Ca fornixtamalisation or extrusion in blue maize has notbeen reported and it can represent an advantagebecause it produces near-neutral pH values whichwould minimise the degradation of antioxidants(Brouillard 1982 Rein 2005) and less damage in thestarch improving the physical and chemical propertiesof masa tortilla and related products The novel con-tribution of this investigation allows the researcher toevaluate the effect of the calcium lactate on the physi-cal properties on the blue maize flour that had notresearched before The aim of this study was to evalu-ate the effect of Ca(OH)2 and C6H10O6Ca concentra-tions on the functional and physical properties ofextruded and nixtamalised blue maize flours
Materials and methods
Materials
Blue maize (Zea mays L) from Babicora ChihuahuaMexico was used Calcium hydroxide [Ca(OH)2] andcalcium lactate [C6H10O6Ca] were used as the calciumsources Proximal analysis was performed for maizecharacterisation Test weight (Method 14-40 AACC
2000) and flotation index (Salinas et al 1992) werealso determined
Extrusion process
Blue maize kernel was milled in a hammer mill (Pulvexmodel 200 Mexico) with a 5-mm sieve to obtain 2- to3-mm grits and fine powder Lots (850 g) of milled bluemaize were mixed separately with different concentra-tions of Ca(OH)2 (01 02 and 03) andC6H10O6Ca (03 06 and 09) Then each lot wasmoisturised with water to reach a moisture content of30 A lot without added calcium was prepared simi-larly to serve as a control (EF control) Each lot waspacked in a polyethylene bag stored for 14 h at 4 degCand then extruded in a single-screw extruder (CINVE-STAV-IPN Queretaro Mexico) The extruder had abarrel (length 428 mm diameter 25 mm) with threeindependent electrically heated zones Screw compres-sion ratio was 11 die diameter was 4 mm and thesystem was operated under a 30-Hz speed screw and aconstant feed rate (30 g min1) which was kept con-stant Processing temperatures in the different zones(feed compression and die) were kept constant at50 degC 70 degC and 80 degC respectively During eachexperimental run the extruder was operated at a steadystate for each condition set This condition was moni-tored and controlled with constant amperage Theextrudate samples were collected and dried at 45 degC for48 h in forced-air convection oven until a moisturecontent of 009 to 011 g kg1 dm (dry matter) wasachieved These extrudates were ground sieved(08 mm) and packed in hermetically sealed plastic bagsand stored in the dark at 4 degC until analysis
Nixtamalisation process
One-kilogram lots of blue maize were nixtamalisedusing two different calcium solutions One lot wascooked in a solution of 1 Ca(OH)2 and the other wascooked in a solution of 295 C6H10O6Ca in a 13maizesolution ratio at 90 degC for 40 min followed by15 h of steeping The cooking liquor (nejayote) wasdiscarded and the cooked grain (nixtamal) was washedtwice with water to remove excess Ca(OH)2 orC6H10O6Ca The nixtamal was ground in a stone mill(FUMASA Mexico) and dried using a flash dryer withan input temperature of 295 degC and an output tempera-ture of 90 degC The dehydrated flours were groundsieved (08 mm) and packed in hermetically sealed plas-tic bags and stored in the dark at 4 degC until analysis

(1998) methods 95002 96052 92039 96209 and92303 respectively
pHThe pH value was determined by the standard AACC(2000) method using a pH meter (Corning PinnacleCorning Inc New York) calibrated with standardbuffers The analysis was carried out in triplicate
Functional properties of blue maize flours
Expansion indexThe expansion index (EI) was calculated for 20 sam-ples by dividing the average diameter of the extrudedproducts by the internal diameter of the extruder dienozzle (Balandran-Quintana et al 1998 Zazueta-Morales et al 2002)
Bulk densityBulk density (BD) was determined by pouring theground extrudate (4060 mesh) into a cylindricalcontainer scraping off excess extrudate and dividingthe net weight of the powder by the volume of thecontainer (Moreyra amp Peleg 1981) Bulk density wasexpressed in kilograms per litre (kg L1) The analysiswas done in triplicate and mean values were reported
Water absorption and water solubility indexesThe water absorption index (WAI) and water solubil-ity index (WSI) were determined in triplicate followingthe procedures described by Anderson et al (1969)and were expressed as percentage The methods mea-sure the quantity of water incorporated in the flourand also the soluble solids dissolved in water at 30 degCSamples were weighed (25 g) into plastic tubes andmixed with 30 mL of distilled water The samples weremanually shaken the slurries were centrifuged for10 min at 3200 g (Thermo IEC model CL3-R USA)and the supernatant was decanted into preweighedporcelain capsules Capsules were dried for 24 h at105 degC and weighed The gel remaining in the tubesafter decanting the supernatant was weighed The ratiobetween gel-forming solids and soluble solids was mea-sured as grams of water per gram of flour
Physical properties of blue maize flours
Thermal properties of blue maize extruded floursThe gelatinisation temperature and enthalpy of starchgelatinisation were determined by differential scanningcalorimetry following the method described by Ruiz-Gutierrez et al (2011) Two milligrams of flour wasplaced in a pan with 20 lL of distilled water The panwas sealed hermetically an empty pan was used as areference The calorimeter from TA Instruments (Q-200Crawley UK) with a program of 30 degC to 110 degC and
a temperature ramp of 5 degC min1 was used The ther-mograms obtained were analysed with Universal Analy-sis software (TA Instruments Crawley UK) Thestarch gelatinisation onset temperature (To) peak tem-perature (Tp) and end temperature (Te) were obtainedfrom the thermograms The gelatinisation enthalpy(DHg) was obtained by integrating the area under thecurve Each determination was done in duplicate
Pasting properties of the extruded floursThe apparent viscosity of the flours was measuredaccording to the method described by Zazueta-Morales et al (2002) using a Rapid Visco Analyser(RVA SUPER 4 Newport Scientific Sydney Austra-lia) Flour sample suspensions were prepared by weigh-ing 4 g of extrudates milled and dried (50 2 degC 12h) with 475 to 85 moisture content into an RVAcanister and individually adjusting each sample to thetotal weight of 28 g using distilled water The rotatingpaddles were held at 50 degC for 2 min to stabilise thetemperature and ensure uniform dispersion thenheated to 92 degC at 56 degC min1 which was held con-stant for 5 min then cooled to 50 degC at the same rateand finally held at 50 degC for 1 min The viscosity at92 degC (V92) minimum viscosity (MinV or lowest vis-cosity at the end of heating constant period at 92 degC)and final viscosity (FinV or maximum viscosityattained during cooling to or holding at 50 degC) wererecorded The total setback viscosity (final minus mini-mum viscosity) was calculated from these parametervalues The viscosity with RVA was obtained in RVUunits (1 RVU = 10 centipoises) Two determinations ofeach treatment were performed
Scanning electron microscopyFlour samples with particle sizes lt015 mm and mois-ture content of 1 were stuck to stubs and coatedwith a gold layer in a high vacuum using a Dentonvacuum evaporator (Desk II) set to a pressure of7031 9 102 kg cm2 The samples were examinedusing a scanning electron microscope (JSM-5800LVJEOL Akishima Japan) equipped with a secondaryelectron detector at an acceleration rate of 10 kV
Statistical analysis
The results were analysed by nested ANOVA wherefactor A was the calcium source [Ca(OH)2 andC6H10O6Ca] and factor B that was nested in A wasthe concentration of each calcium source [01 02and 03 for Ca(OH)2 and 03 06 and 09 forC6H10O6Ca] In addition a contrast analysis of themean differences between the results for EF and NFwas performed Significance was defined as P lt 005using SAS software version 92 (2007) (SAS InstituteInc Cary NC)

Results and discussion
Blue maize characterisation
The proximate composition of blue maize is showedin Table 1 The pH test weight and the flotationindex were 587 7333 272 kg hL1 and 9466 057 kg hL1 respectively which were higher thanthose of other genotypes such as the white and yel-low hybrids (Gutierrez-Uribe et al 2010) Theseproperties are related to endosperm texture Betranet al (2000) indicated that most of blue maizegenotypes possess a floury endosperm that requiresless cooking time
Expansion index
The EI of the extruded blue maize (Table 2) was notaffected (P gt 005) by the calcium source or concentra-tion However the EI of the EF prepared without acalcium source was greater and significantly differentfrom that of the extruded prepared with either calciumsource thus a lower calcium concentration resulted ina higher EI The EI values for extruded flours indicateto some extent the starch damage caused by the extru-sion process which could result in sticky masa andtortilla with certain hardness degree but with
application perhaps for the elaboration of maizesnacks Zazueta-Morales et al (2002) and Martınez-Bustos et al (1998) reported similar EI results formaize extrudates The decrease in the EI can be attrib-uted to the damage in the starch molecules caused byCa(OH)2 Kervinen et al (1984) reported that bothacid and alkaline treatments during the extrusion pro-cess significantly decreased the molecular weight of thestarch decreasing its expansion The starchndashcalciumcomplexes restrict the extent of the flash-off of internalmoisture after the extrudate emerges from the die(Zazueta-Morales et al 2002) because the calciumions electrostatically bind to the OH groups of thestarch making the molecule more compact (Camire ampClydesdale 1981)
Bulk density
Despite that the BD values are similar some significantdifferences can be seen (Table 2) Contrast analysisrevealed that the BD for EF was slightly increased ascalcium hydroxide concentration increases NF withboth calcium sources showed similar BD values to theEF with added calcium being different to the EF con-trol which showed the lowest BD value Thus higherconcentration of Ca(OH)2 induced an increase in theBD values This effect can be related to the EI obtainedwhere a high EI results in a low BD of the EF preparedwithout calcium source These results are similar tothose reported by Martınez-Bustos et al (1998) andZazueta-Morales et al (2001) for maize instant floursMost BD values for EF match the values obtained forNF suggesting that EF could be used for tortillas(slightly harder) as well as for maize snacks production

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

(Received 26 April 2013 Accepted in revised form 12 August 2013)
Summary The effects of different concentrations of calcium hydroxide [Ca(OH)2] and calcium lactate [C6H10O6Ca]
on the functional and physical properties of extruded (EF) and nixtamalised (NF) blue maize flours were
evaluated Calcium source and concentration showed no significant effects on the EF expansion index
The water absorption index (WAI) of EF decreased as the concentrations of both calcium sources
increased and NF with C6H10O6Ca had the lowest WAI The thermal and pasting properties of NFs were
higher than those of EF NF with C6H10O6Ca showed the highest final viscosity (FinV) indicating less
damage to the starch granules and this was correlated with microscopic analysis In contrast the FinV of
EFs was significantly affected by calcium source and concentration Extrusion with 03 and nixtamalisa-
tion at 295 of C6H10O6Ca yielded high WAI value and the best rheological properties in maize flour
respectively These results suggest the use of C6H10O6Ca in extrusion or nixtamalisation to produce blue
maize flours for tortilla or snacks with antioxidants

Introduction
Pigmented maize has received increased attention inthe last decade because of the consumer demand forhealthy nixtamalised corn products such as tortillasand tacos Anthocyanins give colour to the grains andare found mainly in the pericarp andor the aleuronelayer (Salinas-Moreno et al 1999) They have nutra-ceutical properties with possible health benefits (Leeet al 2005) During nixtamalisation the maize iscooked and steeped in calcium hydroxide [Ca(OH)2]solution to obtain nixtamal The pericarp is softenedand removed which allows calcium and water to dif-fuse into the grain causing physicochemical changes(Steffe amp Singh 1980) in starch protein and germthese changes affect the organoleptic properties of
masa (dough) flour tortillas and other nixtamalisedmaize products Blue maize nixtamalisation has thedrawback that with the removal of pericarp anthocya-nin and polyphenolic derivate compounds are also lostby leaching and instability at high pH values (Pflugfel-der et al 1988 Cortes-Gomez et al 2006) resultingin the varying colours of nixtamalised products Onthe other hand the extrusion cooking process has beenused to manufacture instant maize flour (Mensah-Agyapong amp Horner 1992 Gomez Aldapa et al1996) During this process the Ca(OH)2 addition isnecessary to provoke the physicochemical changes inthe starch to obtain flour masa and tortillas with simi-lar characteristics to nixtamalised maize flour besidesthat lime represents a calcium source to improve thenutritional products valueThe effects of lime during nixtamalisation and extru-

characteristics of blue maize flour have been reported(Cortes-Gomez et al 2005 Del Pozo-Insfran et al2007 Aguayo-Rojas et al 2012) However the use ofother calcium sources that generate less alkaline solu-tions for processing blue maize has not reported Pre-vious studies have shown that less alkaline conditionsdecrease the average molecular weight of starch with-out affecting the structural characteristics of the prod-uct (Kervinen et al 1984 Pan et al 1998) Thestructural characteristics of maize products have beenrelated to calciumndashstarch interaction during gelatinisa-tion studies and processing (Tovar et al 2004 Cortes-Gomez et al 2005) Robles et al (1988) and Mendezet al (2006) found that the calciumndashstarch interactionafter nixtamalisation causes an increase in the gelatini-sation temperature and enthalpy of starch Thechanges that are produced in the starch granules maybe evaluated through rheological functional and tex-tural properties of the final products (Robles et al1988 Mondragon et al 2004 Mendez et al 2006)The effect of alkalinity and calcium concentration onthe physicochemical and functional properties on theextruded and nixtamalised flour has been evaluated inprevious studies (Zazueta-Morales et al 2002 Mora-Rochın et al 2010 Aguayo-Rojas et al 2012)Although Ca(OH)2 has been used traditionally othercombined or individual compounds with or withoutcalcium have been studied in nixtamalisation (Robleset al 1988 Maya et al 2010) Ruiz-Gutierrez et al(2011) reported that white maize nixtamalisation withcalcium lactate [C6H10O6Ca] resulted in tortillas withgood colour and texture The use of C6H10O6Ca fornixtamalisation or extrusion in blue maize has notbeen reported and it can represent an advantagebecause it produces near-neutral pH values whichwould minimise the degradation of antioxidants(Brouillard 1982 Rein 2005) and less damage in thestarch improving the physical and chemical propertiesof masa tortilla and related products The novel con-tribution of this investigation allows the researcher toevaluate the effect of the calcium lactate on the physi-cal properties on the blue maize flour that had notresearched before The aim of this study was to evalu-ate the effect of Ca(OH)2 and C6H10O6Ca concentra-tions on the functional and physical properties ofextruded and nixtamalised blue maize flours
Materials and methods
Materials
Blue maize (Zea mays L) from Babicora ChihuahuaMexico was used Calcium hydroxide [Ca(OH)2] andcalcium lactate [C6H10O6Ca] were used as the calciumsources Proximal analysis was performed for maizecharacterisation Test weight (Method 14-40 AACC
2000) and flotation index (Salinas et al 1992) werealso determined
Extrusion process
Blue maize kernel was milled in a hammer mill (Pulvexmodel 200 Mexico) with a 5-mm sieve to obtain 2- to3-mm grits and fine powder Lots (850 g) of milled bluemaize were mixed separately with different concentra-tions of Ca(OH)2 (01 02 and 03) andC6H10O6Ca (03 06 and 09) Then each lot wasmoisturised with water to reach a moisture content of30 A lot without added calcium was prepared simi-larly to serve as a control (EF control) Each lot waspacked in a polyethylene bag stored for 14 h at 4 degCand then extruded in a single-screw extruder (CINVE-STAV-IPN Queretaro Mexico) The extruder had abarrel (length 428 mm diameter 25 mm) with threeindependent electrically heated zones Screw compres-sion ratio was 11 die diameter was 4 mm and thesystem was operated under a 30-Hz speed screw and aconstant feed rate (30 g min1) which was kept con-stant Processing temperatures in the different zones(feed compression and die) were kept constant at50 degC 70 degC and 80 degC respectively During eachexperimental run the extruder was operated at a steadystate for each condition set This condition was moni-tored and controlled with constant amperage Theextrudate samples were collected and dried at 45 degC for48 h in forced-air convection oven until a moisturecontent of 009 to 011 g kg1 dm (dry matter) wasachieved These extrudates were ground sieved(08 mm) and packed in hermetically sealed plastic bagsand stored in the dark at 4 degC until analysis
Nixtamalisation process
One-kilogram lots of blue maize were nixtamalisedusing two different calcium solutions One lot wascooked in a solution of 1 Ca(OH)2 and the other wascooked in a solution of 295 C6H10O6Ca in a 13maizesolution ratio at 90 degC for 40 min followed by15 h of steeping The cooking liquor (nejayote) wasdiscarded and the cooked grain (nixtamal) was washedtwice with water to remove excess Ca(OH)2 orC6H10O6Ca The nixtamal was ground in a stone mill(FUMASA Mexico) and dried using a flash dryer withan input temperature of 295 degC and an output tempera-ture of 90 degC The dehydrated flours were groundsieved (08 mm) and packed in hermetically sealed plas-tic bags and stored in the dark at 4 degC until analysis

(1998) methods 95002 96052 92039 96209 and92303 respectively
pHThe pH value was determined by the standard AACC(2000) method using a pH meter (Corning PinnacleCorning Inc New York) calibrated with standardbuffers The analysis was carried out in triplicate
Functional properties of blue maize flours
Expansion indexThe expansion index (EI) was calculated for 20 sam-ples by dividing the average diameter of the extrudedproducts by the internal diameter of the extruder dienozzle (Balandran-Quintana et al 1998 Zazueta-Morales et al 2002)
Bulk densityBulk density (BD) was determined by pouring theground extrudate (4060 mesh) into a cylindricalcontainer scraping off excess extrudate and dividingthe net weight of the powder by the volume of thecontainer (Moreyra amp Peleg 1981) Bulk density wasexpressed in kilograms per litre (kg L1) The analysiswas done in triplicate and mean values were reported
Water absorption and water solubility indexesThe water absorption index (WAI) and water solubil-ity index (WSI) were determined in triplicate followingthe procedures described by Anderson et al (1969)and were expressed as percentage The methods mea-sure the quantity of water incorporated in the flourand also the soluble solids dissolved in water at 30 degCSamples were weighed (25 g) into plastic tubes andmixed with 30 mL of distilled water The samples weremanually shaken the slurries were centrifuged for10 min at 3200 g (Thermo IEC model CL3-R USA)and the supernatant was decanted into preweighedporcelain capsules Capsules were dried for 24 h at105 degC and weighed The gel remaining in the tubesafter decanting the supernatant was weighed The ratiobetween gel-forming solids and soluble solids was mea-sured as grams of water per gram of flour
Physical properties of blue maize flours
Thermal properties of blue maize extruded floursThe gelatinisation temperature and enthalpy of starchgelatinisation were determined by differential scanningcalorimetry following the method described by Ruiz-Gutierrez et al (2011) Two milligrams of flour wasplaced in a pan with 20 lL of distilled water The panwas sealed hermetically an empty pan was used as areference The calorimeter from TA Instruments (Q-200Crawley UK) with a program of 30 degC to 110 degC and
a temperature ramp of 5 degC min1 was used The ther-mograms obtained were analysed with Universal Analy-sis software (TA Instruments Crawley UK) Thestarch gelatinisation onset temperature (To) peak tem-perature (Tp) and end temperature (Te) were obtainedfrom the thermograms The gelatinisation enthalpy(DHg) was obtained by integrating the area under thecurve Each determination was done in duplicate
Pasting properties of the extruded floursThe apparent viscosity of the flours was measuredaccording to the method described by Zazueta-Morales et al (2002) using a Rapid Visco Analyser(RVA SUPER 4 Newport Scientific Sydney Austra-lia) Flour sample suspensions were prepared by weigh-ing 4 g of extrudates milled and dried (50 2 degC 12h) with 475 to 85 moisture content into an RVAcanister and individually adjusting each sample to thetotal weight of 28 g using distilled water The rotatingpaddles were held at 50 degC for 2 min to stabilise thetemperature and ensure uniform dispersion thenheated to 92 degC at 56 degC min1 which was held con-stant for 5 min then cooled to 50 degC at the same rateand finally held at 50 degC for 1 min The viscosity at92 degC (V92) minimum viscosity (MinV or lowest vis-cosity at the end of heating constant period at 92 degC)and final viscosity (FinV or maximum viscosityattained during cooling to or holding at 50 degC) wererecorded The total setback viscosity (final minus mini-mum viscosity) was calculated from these parametervalues The viscosity with RVA was obtained in RVUunits (1 RVU = 10 centipoises) Two determinations ofeach treatment were performed
Scanning electron microscopyFlour samples with particle sizes lt015 mm and mois-ture content of 1 were stuck to stubs and coatedwith a gold layer in a high vacuum using a Dentonvacuum evaporator (Desk II) set to a pressure of7031 9 102 kg cm2 The samples were examinedusing a scanning electron microscope (JSM-5800LVJEOL Akishima Japan) equipped with a secondaryelectron detector at an acceleration rate of 10 kV
Statistical analysis
The results were analysed by nested ANOVA wherefactor A was the calcium source [Ca(OH)2 andC6H10O6Ca] and factor B that was nested in A wasthe concentration of each calcium source [01 02and 03 for Ca(OH)2 and 03 06 and 09 forC6H10O6Ca] In addition a contrast analysis of themean differences between the results for EF and NFwas performed Significance was defined as P lt 005using SAS software version 92 (2007) (SAS InstituteInc Cary NC)

Results and discussion
Blue maize characterisation
The proximate composition of blue maize is showedin Table 1 The pH test weight and the flotationindex were 587 7333 272 kg hL1 and 9466 057 kg hL1 respectively which were higher thanthose of other genotypes such as the white and yel-low hybrids (Gutierrez-Uribe et al 2010) Theseproperties are related to endosperm texture Betranet al (2000) indicated that most of blue maizegenotypes possess a floury endosperm that requiresless cooking time
Expansion index
The EI of the extruded blue maize (Table 2) was notaffected (P gt 005) by the calcium source or concentra-tion However the EI of the EF prepared without acalcium source was greater and significantly differentfrom that of the extruded prepared with either calciumsource thus a lower calcium concentration resulted ina higher EI The EI values for extruded flours indicateto some extent the starch damage caused by the extru-sion process which could result in sticky masa andtortilla with certain hardness degree but with
application perhaps for the elaboration of maizesnacks Zazueta-Morales et al (2002) and Martınez-Bustos et al (1998) reported similar EI results formaize extrudates The decrease in the EI can be attrib-uted to the damage in the starch molecules caused byCa(OH)2 Kervinen et al (1984) reported that bothacid and alkaline treatments during the extrusion pro-cess significantly decreased the molecular weight of thestarch decreasing its expansion The starchndashcalciumcomplexes restrict the extent of the flash-off of internalmoisture after the extrudate emerges from the die(Zazueta-Morales et al 2002) because the calciumions electrostatically bind to the OH groups of thestarch making the molecule more compact (Camire ampClydesdale 1981)
Bulk density
Despite that the BD values are similar some significantdifferences can be seen (Table 2) Contrast analysisrevealed that the BD for EF was slightly increased ascalcium hydroxide concentration increases NF withboth calcium sources showed similar BD values to theEF with added calcium being different to the EF con-trol which showed the lowest BD value Thus higherconcentration of Ca(OH)2 induced an increase in theBD values This effect can be related to the EI obtainedwhere a high EI results in a low BD of the EF preparedwithout calcium source These results are similar tothose reported by Martınez-Bustos et al (1998) andZazueta-Morales et al (2001) for maize instant floursMost BD values for EF match the values obtained forNF suggesting that EF could be used for tortillas(slightly harder) as well as for maize snacks production

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

Summary The effects of different concentrations of calcium hydroxide [Ca(OH)2] and calcium lactate [C6H10O6Ca]
on the functional and physical properties of extruded (EF) and nixtamalised (NF) blue maize flours were
evaluated Calcium source and concentration showed no significant effects on the EF expansion index
The water absorption index (WAI) of EF decreased as the concentrations of both calcium sources
increased and NF with C6H10O6Ca had the lowest WAI The thermal and pasting properties of NFs were
higher than those of EF NF with C6H10O6Ca showed the highest final viscosity (FinV) indicating less
damage to the starch granules and this was correlated with microscopic analysis In contrast the FinV of
EFs was significantly affected by calcium source and concentration Extrusion with 03 and nixtamalisa-
tion at 295 of C6H10O6Ca yielded high WAI value and the best rheological properties in maize flour
respectively These results suggest the use of C6H10O6Ca in extrusion or nixtamalisation to produce blue
maize flours for tortilla or snacks with antioxidants

Introduction
Pigmented maize has received increased attention inthe last decade because of the consumer demand forhealthy nixtamalised corn products such as tortillasand tacos Anthocyanins give colour to the grains andare found mainly in the pericarp andor the aleuronelayer (Salinas-Moreno et al 1999) They have nutra-ceutical properties with possible health benefits (Leeet al 2005) During nixtamalisation the maize iscooked and steeped in calcium hydroxide [Ca(OH)2]solution to obtain nixtamal The pericarp is softenedand removed which allows calcium and water to dif-fuse into the grain causing physicochemical changes(Steffe amp Singh 1980) in starch protein and germthese changes affect the organoleptic properties of
masa (dough) flour tortillas and other nixtamalisedmaize products Blue maize nixtamalisation has thedrawback that with the removal of pericarp anthocya-nin and polyphenolic derivate compounds are also lostby leaching and instability at high pH values (Pflugfel-der et al 1988 Cortes-Gomez et al 2006) resultingin the varying colours of nixtamalised products Onthe other hand the extrusion cooking process has beenused to manufacture instant maize flour (Mensah-Agyapong amp Horner 1992 Gomez Aldapa et al1996) During this process the Ca(OH)2 addition isnecessary to provoke the physicochemical changes inthe starch to obtain flour masa and tortillas with simi-lar characteristics to nixtamalised maize flour besidesthat lime represents a calcium source to improve thenutritional products valueThe effects of lime during nixtamalisation and extru-

characteristics of blue maize flour have been reported(Cortes-Gomez et al 2005 Del Pozo-Insfran et al2007 Aguayo-Rojas et al 2012) However the use ofother calcium sources that generate less alkaline solu-tions for processing blue maize has not reported Pre-vious studies have shown that less alkaline conditionsdecrease the average molecular weight of starch with-out affecting the structural characteristics of the prod-uct (Kervinen et al 1984 Pan et al 1998) Thestructural characteristics of maize products have beenrelated to calciumndashstarch interaction during gelatinisa-tion studies and processing (Tovar et al 2004 Cortes-Gomez et al 2005) Robles et al (1988) and Mendezet al (2006) found that the calciumndashstarch interactionafter nixtamalisation causes an increase in the gelatini-sation temperature and enthalpy of starch Thechanges that are produced in the starch granules maybe evaluated through rheological functional and tex-tural properties of the final products (Robles et al1988 Mondragon et al 2004 Mendez et al 2006)The effect of alkalinity and calcium concentration onthe physicochemical and functional properties on theextruded and nixtamalised flour has been evaluated inprevious studies (Zazueta-Morales et al 2002 Mora-Rochın et al 2010 Aguayo-Rojas et al 2012)Although Ca(OH)2 has been used traditionally othercombined or individual compounds with or withoutcalcium have been studied in nixtamalisation (Robleset al 1988 Maya et al 2010) Ruiz-Gutierrez et al(2011) reported that white maize nixtamalisation withcalcium lactate [C6H10O6Ca] resulted in tortillas withgood colour and texture The use of C6H10O6Ca fornixtamalisation or extrusion in blue maize has notbeen reported and it can represent an advantagebecause it produces near-neutral pH values whichwould minimise the degradation of antioxidants(Brouillard 1982 Rein 2005) and less damage in thestarch improving the physical and chemical propertiesof masa tortilla and related products The novel con-tribution of this investigation allows the researcher toevaluate the effect of the calcium lactate on the physi-cal properties on the blue maize flour that had notresearched before The aim of this study was to evalu-ate the effect of Ca(OH)2 and C6H10O6Ca concentra-tions on the functional and physical properties ofextruded and nixtamalised blue maize flours
Materials and methods
Materials
Blue maize (Zea mays L) from Babicora ChihuahuaMexico was used Calcium hydroxide [Ca(OH)2] andcalcium lactate [C6H10O6Ca] were used as the calciumsources Proximal analysis was performed for maizecharacterisation Test weight (Method 14-40 AACC
2000) and flotation index (Salinas et al 1992) werealso determined
Extrusion process
Blue maize kernel was milled in a hammer mill (Pulvexmodel 200 Mexico) with a 5-mm sieve to obtain 2- to3-mm grits and fine powder Lots (850 g) of milled bluemaize were mixed separately with different concentra-tions of Ca(OH)2 (01 02 and 03) andC6H10O6Ca (03 06 and 09) Then each lot wasmoisturised with water to reach a moisture content of30 A lot without added calcium was prepared simi-larly to serve as a control (EF control) Each lot waspacked in a polyethylene bag stored for 14 h at 4 degCand then extruded in a single-screw extruder (CINVE-STAV-IPN Queretaro Mexico) The extruder had abarrel (length 428 mm diameter 25 mm) with threeindependent electrically heated zones Screw compres-sion ratio was 11 die diameter was 4 mm and thesystem was operated under a 30-Hz speed screw and aconstant feed rate (30 g min1) which was kept con-stant Processing temperatures in the different zones(feed compression and die) were kept constant at50 degC 70 degC and 80 degC respectively During eachexperimental run the extruder was operated at a steadystate for each condition set This condition was moni-tored and controlled with constant amperage Theextrudate samples were collected and dried at 45 degC for48 h in forced-air convection oven until a moisturecontent of 009 to 011 g kg1 dm (dry matter) wasachieved These extrudates were ground sieved(08 mm) and packed in hermetically sealed plastic bagsand stored in the dark at 4 degC until analysis
Nixtamalisation process
One-kilogram lots of blue maize were nixtamalisedusing two different calcium solutions One lot wascooked in a solution of 1 Ca(OH)2 and the other wascooked in a solution of 295 C6H10O6Ca in a 13maizesolution ratio at 90 degC for 40 min followed by15 h of steeping The cooking liquor (nejayote) wasdiscarded and the cooked grain (nixtamal) was washedtwice with water to remove excess Ca(OH)2 orC6H10O6Ca The nixtamal was ground in a stone mill(FUMASA Mexico) and dried using a flash dryer withan input temperature of 295 degC and an output tempera-ture of 90 degC The dehydrated flours were groundsieved (08 mm) and packed in hermetically sealed plas-tic bags and stored in the dark at 4 degC until analysis

pHThe pH value was determined by the standard AACC(2000) method using a pH meter (Corning PinnacleCorning Inc New York) calibrated with standardbuffers The analysis was carried out in triplicate
Functional properties of blue maize flours
Expansion indexThe expansion index (EI) was calculated for 20 sam-ples by dividing the average diameter of the extrudedproducts by the internal diameter of the extruder dienozzle (Balandran-Quintana et al 1998 Zazueta-Morales et al 2002)
Bulk densityBulk density (BD) was determined by pouring theground extrudate (4060 mesh) into a cylindricalcontainer scraping off excess extrudate and dividingthe net weight of the powder by the volume of thecontainer (Moreyra amp Peleg 1981) Bulk density wasexpressed in kilograms per litre (kg L1) The analysiswas done in triplicate and mean values were reported
Water absorption and water solubility indexesThe water absorption index (WAI) and water solubil-ity index (WSI) were determined in triplicate followingthe procedures described by Anderson et al (1969)and were expressed as percentage The methods mea-sure the quantity of water incorporated in the flourand also the soluble solids dissolved in water at 30 degCSamples were weighed (25 g) into plastic tubes andmixed with 30 mL of distilled water The samples weremanually shaken the slurries were centrifuged for10 min at 3200 g (Thermo IEC model CL3-R USA)and the supernatant was decanted into preweighedporcelain capsules Capsules were dried for 24 h at105 degC and weighed The gel remaining in the tubesafter decanting the supernatant was weighed The ratiobetween gel-forming solids and soluble solids was mea-sured as grams of water per gram of flour

Thermal properties of blue maize extruded floursThe gelatinisation temperature and enthalpy of starchgelatinisation were determined by differential scanningcalorimetry following the method described by Ruiz-Gutierrez et al (2011) Two milligrams of flour wasplaced in a pan with 20 lL of distilled water The panwas sealed hermetically an empty pan was used as areference The calorimeter from TA Instruments (Q-200Crawley UK) with a program of 30 degC to 110 degC and
a temperature ramp of 5 degC min1 was used The ther-mograms obtained were analysed with Universal Analy-sis software (TA Instruments Crawley UK) Thestarch gelatinisation onset temperature (To) peak tem-perature (Tp) and end temperature (Te) were obtainedfrom the thermograms The gelatinisation enthalpy(DHg) was obtained by integrating the area under thecurve Each determination was done in duplicate
Pasting properties of the extruded floursThe apparent viscosity of the flours was measuredaccording to the method described by Zazueta-Morales et al (2002) using a Rapid Visco Analyser(RVA SUPER 4 Newport Scientific Sydney Austra-lia) Flour sample suspensions were prepared by weigh-ing 4 g of extrudates milled and dried (50 2 degC 12h) with 475 to 85 moisture content into an RVAcanister and individually adjusting each sample to thetotal weight of 28 g using distilled water The rotatingpaddles were held at 50 degC for 2 min to stabilise thetemperature and ensure uniform dispersion thenheated to 92 degC at 56 degC min1 which was held con-stant for 5 min then cooled to 50 degC at the same rateand finally held at 50 degC for 1 min The viscosity at92 degC (V92) minimum viscosity (MinV or lowest vis-cosity at the end of heating constant period at 92 degC)and final viscosity (FinV or maximum viscosityattained during cooling to or holding at 50 degC) wererecorded The total setback viscosity (final minus mini-mum viscosity) was calculated from these parametervalues The viscosity with RVA was obtained in RVUunits (1 RVU = 10 centipoises) Two determinations ofeach treatment were performed
Scanning electron microscopyFlour samples with particle sizes lt015 mm and mois-ture content of 1 were stuck to stubs and coatedwith a gold layer in a high vacuum using a Dentonvacuum evaporator (Desk II) set to a pressure of7031 9 102 kg cm2 The samples were examinedusing a scanning electron microscope (JSM-5800LVJEOL Akishima Japan) equipped with a secondaryelectron detector at an acceleration rate of 10 kV
Statistical analysis
The results were analysed by nested ANOVA wherefactor A was the calcium source [Ca(OH)2 andC6H10O6Ca] and factor B that was nested in A wasthe concentration of each calcium source [01 02and 03 for Ca(OH)2 and 03 06 and 09 forC6H10O6Ca] In addition a contrast analysis of themean differences between the results for EF and NFwas performed Significance was defined as P lt 005using SAS software version 92 (2007) (SAS InstituteInc Cary NC)

Results and discussion
Blue maize characterisation
The proximate composition of blue maize is showedin Table 1 The pH test weight and the flotationindex were 587 7333 272 kg hL1 and 9466 057 kg hL1 respectively which were higher thanthose of other genotypes such as the white and yel-low hybrids (Gutierrez-Uribe et al 2010) Theseproperties are related to endosperm texture Betranet al (2000) indicated that most of blue maizegenotypes possess a floury endosperm that requiresless cooking time
Expansion index
The EI of the extruded blue maize (Table 2) was notaffected (P gt 005) by the calcium source or concentra-tion However the EI of the EF prepared without acalcium source was greater and significantly differentfrom that of the extruded prepared with either calciumsource thus a lower calcium concentration resulted ina higher EI The EI values for extruded flours indicateto some extent the starch damage caused by the extru-sion process which could result in sticky masa andtortilla with certain hardness degree but with
application perhaps for the elaboration of maizesnacks Zazueta-Morales et al (2002) and Martınez-Bustos et al (1998) reported similar EI results formaize extrudates The decrease in the EI can be attrib-uted to the damage in the starch molecules caused byCa(OH)2 Kervinen et al (1984) reported that bothacid and alkaline treatments during the extrusion pro-cess significantly decreased the molecular weight of thestarch decreasing its expansion The starchndashcalciumcomplexes restrict the extent of the flash-off of internalmoisture after the extrudate emerges from the die(Zazueta-Morales et al 2002) because the calciumions electrostatically bind to the OH groups of thestarch making the molecule more compact (Camire ampClydesdale 1981)
Bulk density
Despite that the BD values are similar some significantdifferences can be seen (Table 2) Contrast analysisrevealed that the BD for EF was slightly increased ascalcium hydroxide concentration increases NF withboth calcium sources showed similar BD values to theEF with added calcium being different to the EF con-trol which showed the lowest BD value Thus higherconcentration of Ca(OH)2 induced an increase in theBD values This effect can be related to the EI obtainedwhere a high EI results in a low BD of the EF preparedwithout calcium source These results are similar tothose reported by Martınez-Bustos et al (1998) andZazueta-Morales et al (2001) for maize instant floursMost BD values for EF match the values obtained forNF suggesting that EF could be used for tortillas(slightly harder) as well as for maize snacks production

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

Summary The effects of different concentrations of calcium hydroxide [Ca(OH)2] and calcium lactate [C6H10O6Ca]
on the functional and physical properties of extruded (EF) and nixtamalised (NF) blue maize flours were
evaluated Calcium source and concentration showed no significant effects on the EF expansion index
The water absorption index (WAI) of EF decreased as the concentrations of both calcium sources
increased and NF with C6H10O6Ca had the lowest WAI The thermal and pasting properties of NFs were
higher than those of EF NF with C6H10O6Ca showed the highest final viscosity (FinV) indicating less
damage to the starch granules and this was correlated with microscopic analysis In contrast the FinV of
EFs was significantly affected by calcium source and concentration Extrusion with 03 and nixtamalisa-
tion at 295 of C6H10O6Ca yielded high WAI value and the best rheological properties in maize flour
respectively These results suggest the use of C6H10O6Ca in extrusion or nixtamalisation to produce blue
maize flours for tortilla or snacks with antioxidants

Introduction
Pigmented maize has received increased attention inthe last decade because of the consumer demand forhealthy nixtamalised corn products such as tortillasand tacos Anthocyanins give colour to the grains andare found mainly in the pericarp andor the aleuronelayer (Salinas-Moreno et al 1999) They have nutra-ceutical properties with possible health benefits (Leeet al 2005) During nixtamalisation the maize iscooked and steeped in calcium hydroxide [Ca(OH)2]solution to obtain nixtamal The pericarp is softenedand removed which allows calcium and water to dif-fuse into the grain causing physicochemical changes(Steffe amp Singh 1980) in starch protein and germthese changes affect the organoleptic properties of
masa (dough) flour tortillas and other nixtamalisedmaize products Blue maize nixtamalisation has thedrawback that with the removal of pericarp anthocya-nin and polyphenolic derivate compounds are also lostby leaching and instability at high pH values (Pflugfel-der et al 1988 Cortes-Gomez et al 2006) resultingin the varying colours of nixtamalised products Onthe other hand the extrusion cooking process has beenused to manufacture instant maize flour (Mensah-Agyapong amp Horner 1992 Gomez Aldapa et al1996) During this process the Ca(OH)2 addition isnecessary to provoke the physicochemical changes inthe starch to obtain flour masa and tortillas with simi-lar characteristics to nixtamalised maize flour besidesthat lime represents a calcium source to improve thenutritional products valueThe effects of lime during nixtamalisation and extru-

characteristics of blue maize flour have been reported(Cortes-Gomez et al 2005 Del Pozo-Insfran et al2007 Aguayo-Rojas et al 2012) However the use ofother calcium sources that generate less alkaline solu-tions for processing blue maize has not reported Pre-vious studies have shown that less alkaline conditionsdecrease the average molecular weight of starch with-out affecting the structural characteristics of the prod-uct (Kervinen et al 1984 Pan et al 1998) Thestructural characteristics of maize products have beenrelated to calciumndashstarch interaction during gelatinisa-tion studies and processing (Tovar et al 2004 Cortes-Gomez et al 2005) Robles et al (1988) and Mendezet al (2006) found that the calciumndashstarch interactionafter nixtamalisation causes an increase in the gelatini-sation temperature and enthalpy of starch Thechanges that are produced in the starch granules maybe evaluated through rheological functional and tex-tural properties of the final products (Robles et al1988 Mondragon et al 2004 Mendez et al 2006)The effect of alkalinity and calcium concentration onthe physicochemical and functional properties on theextruded and nixtamalised flour has been evaluated inprevious studies (Zazueta-Morales et al 2002 Mora-Rochın et al 2010 Aguayo-Rojas et al 2012)Although Ca(OH)2 has been used traditionally othercombined or individual compounds with or withoutcalcium have been studied in nixtamalisation (Robleset al 1988 Maya et al 2010) Ruiz-Gutierrez et al(2011) reported that white maize nixtamalisation withcalcium lactate [C6H10O6Ca] resulted in tortillas withgood colour and texture The use of C6H10O6Ca fornixtamalisation or extrusion in blue maize has notbeen reported and it can represent an advantagebecause it produces near-neutral pH values whichwould minimise the degradation of antioxidants(Brouillard 1982 Rein 2005) and less damage in thestarch improving the physical and chemical propertiesof masa tortilla and related products The novel con-tribution of this investigation allows the researcher toevaluate the effect of the calcium lactate on the physi-cal properties on the blue maize flour that had notresearched before The aim of this study was to evalu-ate the effect of Ca(OH)2 and C6H10O6Ca concentra-tions on the functional and physical properties ofextruded and nixtamalised blue maize flours
Materials and methods
Materials
Blue maize (Zea mays L) from Babicora ChihuahuaMexico was used Calcium hydroxide [Ca(OH)2] andcalcium lactate [C6H10O6Ca] were used as the calciumsources Proximal analysis was performed for maizecharacterisation Test weight (Method 14-40 AACC
2000) and flotation index (Salinas et al 1992) werealso determined
Extrusion process
Blue maize kernel was milled in a hammer mill (Pulvexmodel 200 Mexico) with a 5-mm sieve to obtain 2- to3-mm grits and fine powder Lots (850 g) of milled bluemaize were mixed separately with different concentra-tions of Ca(OH)2 (01 02 and 03) andC6H10O6Ca (03 06 and 09) Then each lot wasmoisturised with water to reach a moisture content of30 A lot without added calcium was prepared simi-larly to serve as a control (EF control) Each lot waspacked in a polyethylene bag stored for 14 h at 4 degCand then extruded in a single-screw extruder (CINVE-STAV-IPN Queretaro Mexico) The extruder had abarrel (length 428 mm diameter 25 mm) with threeindependent electrically heated zones Screw compres-sion ratio was 11 die diameter was 4 mm and thesystem was operated under a 30-Hz speed screw and aconstant feed rate (30 g min1) which was kept con-stant Processing temperatures in the different zones(feed compression and die) were kept constant at50 degC 70 degC and 80 degC respectively During eachexperimental run the extruder was operated at a steadystate for each condition set This condition was moni-tored and controlled with constant amperage Theextrudate samples were collected and dried at 45 degC for48 h in forced-air convection oven until a moisturecontent of 009 to 011 g kg1 dm (dry matter) wasachieved These extrudates were ground sieved(08 mm) and packed in hermetically sealed plastic bagsand stored in the dark at 4 degC until analysis
Nixtamalisation process
One-kilogram lots of blue maize were nixtamalisedusing two different calcium solutions One lot wascooked in a solution of 1 Ca(OH)2 and the other wascooked in a solution of 295 C6H10O6Ca in a 13maizesolution ratio at 90 degC for 40 min followed by15 h of steeping The cooking liquor (nejayote) wasdiscarded and the cooked grain (nixtamal) was washedtwice with water to remove excess Ca(OH)2 orC6H10O6Ca The nixtamal was ground in a stone mill(FUMASA Mexico) and dried using a flash dryer withan input temperature of 295 degC and an output tempera-ture of 90 degC The dehydrated flours were groundsieved (08 mm) and packed in hermetically sealed plas-tic bags and stored in the dark at 4 degC until analysis

pHThe pH value was determined by the standard AACC(2000) method using a pH meter (Corning PinnacleCorning Inc New York) calibrated with standardbuffers The analysis was carried out in triplicate
Functional properties of blue maize flours
Expansion indexThe expansion index (EI) was calculated for 20 sam-ples by dividing the average diameter of the extrudedproducts by the internal diameter of the extruder dienozzle (Balandran-Quintana et al 1998 Zazueta-Morales et al 2002)
Bulk densityBulk density (BD) was determined by pouring theground extrudate (4060 mesh) into a cylindricalcontainer scraping off excess extrudate and dividingthe net weight of the powder by the volume of thecontainer (Moreyra amp Peleg 1981) Bulk density wasexpressed in kilograms per litre (kg L1) The analysiswas done in triplicate and mean values were reported
Water absorption and water solubility indexesThe water absorption index (WAI) and water solubil-ity index (WSI) were determined in triplicate followingthe procedures described by Anderson et al (1969)and were expressed as percentage The methods mea-sure the quantity of water incorporated in the flourand also the soluble solids dissolved in water at 30 degCSamples were weighed (25 g) into plastic tubes andmixed with 30 mL of distilled water The samples weremanually shaken the slurries were centrifuged for10 min at 3200 g (Thermo IEC model CL3-R USA)and the supernatant was decanted into preweighedporcelain capsules Capsules were dried for 24 h at105 degC and weighed The gel remaining in the tubesafter decanting the supernatant was weighed The ratiobetween gel-forming solids and soluble solids was mea-sured as grams of water per gram of flour
Physical properties of blue maize flours
Thermal properties of blue maize extruded floursThe gelatinisation temperature and enthalpy of starchgelatinisation were determined by differential scanningcalorimetry following the method described by Ruiz-Gutierrez et al (2011) Two milligrams of flour wasplaced in a pan with 20 lL of distilled water The panwas sealed hermetically an empty pan was used as areference The calorimeter from TA Instruments (Q-200Crawley UK) with a program of 30 degC to 110 degC and
a temperature ramp of 5 degC min1 was used The ther-mograms obtained were analysed with Universal Analy-sis software (TA Instruments Crawley UK) Thestarch gelatinisation onset temperature (To) peak tem-perature (Tp) and end temperature (Te) were obtainedfrom the thermograms The gelatinisation enthalpy(DHg) was obtained by integrating the area under thecurve Each determination was done in duplicate
Pasting properties of the extruded floursThe apparent viscosity of the flours was measuredaccording to the method described by Zazueta-Morales et al (2002) using a Rapid Visco Analyser(RVA SUPER 4 Newport Scientific Sydney Austra-lia) Flour sample suspensions were prepared by weigh-ing 4 g of extrudates milled and dried (50 2 degC 12h) with 475 to 85 moisture content into an RVAcanister and individually adjusting each sample to thetotal weight of 28 g using distilled water The rotatingpaddles were held at 50 degC for 2 min to stabilise thetemperature and ensure uniform dispersion thenheated to 92 degC at 56 degC min1 which was held con-stant for 5 min then cooled to 50 degC at the same rateand finally held at 50 degC for 1 min The viscosity at92 degC (V92) minimum viscosity (MinV or lowest vis-cosity at the end of heating constant period at 92 degC)and final viscosity (FinV or maximum viscosityattained during cooling to or holding at 50 degC) wererecorded The total setback viscosity (final minus mini-mum viscosity) was calculated from these parametervalues The viscosity with RVA was obtained in RVUunits (1 RVU = 10 centipoises) Two determinations ofeach treatment were performed
Scanning electron microscopyFlour samples with particle sizes lt015 mm and mois-ture content of 1 were stuck to stubs and coatedwith a gold layer in a high vacuum using a Dentonvacuum evaporator (Desk II) set to a pressure of7031 9 102 kg cm2 The samples were examinedusing a scanning electron microscope (JSM-5800LVJEOL Akishima Japan) equipped with a secondaryelectron detector at an acceleration rate of 10 kV
Statistical analysis
The results were analysed by nested ANOVA wherefactor A was the calcium source [Ca(OH)2 andC6H10O6Ca] and factor B that was nested in A wasthe concentration of each calcium source [01 02and 03 for Ca(OH)2 and 03 06 and 09 forC6H10O6Ca] In addition a contrast analysis of themean differences between the results for EF and NFwas performed Significance was defined as P lt 005using SAS software version 92 (2007) (SAS InstituteInc Cary NC)

Results and discussion
Blue maize characterisation
The proximate composition of blue maize is showedin Table 1 The pH test weight and the flotationindex were 587 7333 272 kg hL1 and 9466 057 kg hL1 respectively which were higher thanthose of other genotypes such as the white and yel-low hybrids (Gutierrez-Uribe et al 2010) Theseproperties are related to endosperm texture Betranet al (2000) indicated that most of blue maizegenotypes possess a floury endosperm that requiresless cooking time
Expansion index
The EI of the extruded blue maize (Table 2) was notaffected (P gt 005) by the calcium source or concentra-tion However the EI of the EF prepared without acalcium source was greater and significantly differentfrom that of the extruded prepared with either calciumsource thus a lower calcium concentration resulted ina higher EI The EI values for extruded flours indicateto some extent the starch damage caused by the extru-sion process which could result in sticky masa andtortilla with certain hardness degree but with
application perhaps for the elaboration of maizesnacks Zazueta-Morales et al (2002) and Martınez-Bustos et al (1998) reported similar EI results formaize extrudates The decrease in the EI can be attrib-uted to the damage in the starch molecules caused byCa(OH)2 Kervinen et al (1984) reported that bothacid and alkaline treatments during the extrusion pro-cess significantly decreased the molecular weight of thestarch decreasing its expansion The starchndashcalciumcomplexes restrict the extent of the flash-off of internalmoisture after the extrudate emerges from the die(Zazueta-Morales et al 2002) because the calciumions electrostatically bind to the OH groups of thestarch making the molecule more compact (Camire ampClydesdale 1981)
Bulk density
Despite that the BD values are similar some significantdifferences can be seen (Table 2) Contrast analysisrevealed that the BD for EF was slightly increased ascalcium hydroxide concentration increases NF withboth calcium sources showed similar BD values to theEF with added calcium being different to the EF con-trol which showed the lowest BD value Thus higherconcentration of Ca(OH)2 induced an increase in theBD values This effect can be related to the EI obtainedwhere a high EI results in a low BD of the EF preparedwithout calcium source These results are similar tothose reported by Martınez-Bustos et al (1998) andZazueta-Morales et al (2001) for maize instant floursMost BD values for EF match the values obtained forNF suggesting that EF could be used for tortillas(slightly harder) as well as for maize snacks production
Water absorption index
The WAI of the blue maize EF (Table 2) was affected(P lt 005) by both calcium sources and their

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

Summary The effects of different concentrations of calcium hydroxide [Ca(OH)2] and calcium lactate [C6H10O6Ca]
on the functional and physical properties of extruded (EF) and nixtamalised (NF) blue maize flours were
evaluated Calcium source and concentration showed no significant effects on the EF expansion index
The water absorption index (WAI) of EF decreased as the concentrations of both calcium sources
increased and NF with C6H10O6Ca had the lowest WAI The thermal and pasting properties of NFs were
higher than those of EF NF with C6H10O6Ca showed the highest final viscosity (FinV) indicating less
damage to the starch granules and this was correlated with microscopic analysis In contrast the FinV of
EFs was significantly affected by calcium source and concentration Extrusion with 03 and nixtamalisa-
tion at 295 of C6H10O6Ca yielded high WAI value and the best rheological properties in maize flour
respectively These results suggest the use of C6H10O6Ca in extrusion or nixtamalisation to produce blue
maize flours for tortilla or snacks with antioxidants
Keywords Blue maize calcium hydroxide calcium lactate extrusion nixtamalisation rheological properties
Introduction
Pigmented maize has received increased attention inthe last decade because of the consumer demand forhealthy nixtamalised corn products such as tortillasand tacos Anthocyanins give colour to the grains andare found mainly in the pericarp andor the aleuronelayer (Salinas-Moreno et al 1999) They have nutra-ceutical properties with possible health benefits (Leeet al 2005) During nixtamalisation the maize iscooked and steeped in calcium hydroxide [Ca(OH)2]solution to obtain nixtamal The pericarp is softenedand removed which allows calcium and water to dif-fuse into the grain causing physicochemical changes(Steffe amp Singh 1980) in starch protein and germthese changes affect the organoleptic properties of
masa (dough) flour tortillas and other nixtamalisedmaize products Blue maize nixtamalisation has thedrawback that with the removal of pericarp anthocya-nin and polyphenolic derivate compounds are also lostby leaching and instability at high pH values (Pflugfel-der et al 1988 Cortes-Gomez et al 2006) resultingin the varying colours of nixtamalised products Onthe other hand the extrusion cooking process has beenused to manufacture instant maize flour (Mensah-Agyapong amp Horner 1992 Gomez Aldapa et al1996) During this process the Ca(OH)2 addition isnecessary to provoke the physicochemical changes inthe starch to obtain flour masa and tortillas with simi-lar characteristics to nixtamalised maize flour besidesthat lime represents a calcium source to improve thenutritional products valueThe effects of lime during nixtamalisation and extru-

characteristics of blue maize flour have been reported(Cortes-Gomez et al 2005 Del Pozo-Insfran et al2007 Aguayo-Rojas et al 2012) However the use ofother calcium sources that generate less alkaline solu-tions for processing blue maize has not reported Pre-vious studies have shown that less alkaline conditionsdecrease the average molecular weight of starch with-out affecting the structural characteristics of the prod-uct (Kervinen et al 1984 Pan et al 1998) Thestructural characteristics of maize products have beenrelated to calciumndashstarch interaction during gelatinisa-tion studies and processing (Tovar et al 2004 Cortes-Gomez et al 2005) Robles et al (1988) and Mendezet al (2006) found that the calciumndashstarch interactionafter nixtamalisation causes an increase in the gelatini-sation temperature and enthalpy of starch Thechanges that are produced in the starch granules maybe evaluated through rheological functional and tex-tural properties of the final products (Robles et al1988 Mondragon et al 2004 Mendez et al 2006)The effect of alkalinity and calcium concentration onthe physicochemical and functional properties on theextruded and nixtamalised flour has been evaluated inprevious studies (Zazueta-Morales et al 2002 Mora-Rochın et al 2010 Aguayo-Rojas et al 2012)Although Ca(OH)2 has been used traditionally othercombined or individual compounds with or withoutcalcium have been studied in nixtamalisation (Robleset al 1988 Maya et al 2010) Ruiz-Gutierrez et al(2011) reported that white maize nixtamalisation withcalcium lactate [C6H10O6Ca] resulted in tortillas withgood colour and texture The use of C6H10O6Ca fornixtamalisation or extrusion in blue maize has notbeen reported and it can represent an advantagebecause it produces near-neutral pH values whichwould minimise the degradation of antioxidants(Brouillard 1982 Rein 2005) and less damage in thestarch improving the physical and chemical propertiesof masa tortilla and related products The novel con-tribution of this investigation allows the researcher toevaluate the effect of the calcium lactate on the physi-cal properties on the blue maize flour that had notresearched before The aim of this study was to evalu-ate the effect of Ca(OH)2 and C6H10O6Ca concentra-tions on the functional and physical properties ofextruded and nixtamalised blue maize flours
Materials and methods
Materials
Blue maize (Zea mays L) from Babicora ChihuahuaMexico was used Calcium hydroxide [Ca(OH)2] andcalcium lactate [C6H10O6Ca] were used as the calciumsources Proximal analysis was performed for maizecharacterisation Test weight (Method 14-40 AACC
2000) and flotation index (Salinas et al 1992) werealso determined
Extrusion process
Blue maize kernel was milled in a hammer mill (Pulvexmodel 200 Mexico) with a 5-mm sieve to obtain 2- to3-mm grits and fine powder Lots (850 g) of milled bluemaize were mixed separately with different concentra-tions of Ca(OH)2 (01 02 and 03) andC6H10O6Ca (03 06 and 09) Then each lot wasmoisturised with water to reach a moisture content of30 A lot without added calcium was prepared simi-larly to serve as a control (EF control) Each lot waspacked in a polyethylene bag stored for 14 h at 4 degCand then extruded in a single-screw extruder (CINVE-STAV-IPN Queretaro Mexico) The extruder had abarrel (length 428 mm diameter 25 mm) with threeindependent electrically heated zones Screw compres-sion ratio was 11 die diameter was 4 mm and thesystem was operated under a 30-Hz speed screw and aconstant feed rate (30 g min1) which was kept con-stant Processing temperatures in the different zones(feed compression and die) were kept constant at50 degC 70 degC and 80 degC respectively During eachexperimental run the extruder was operated at a steadystate for each condition set This condition was moni-tored and controlled with constant amperage Theextrudate samples were collected and dried at 45 degC for48 h in forced-air convection oven until a moisturecontent of 009 to 011 g kg1 dm (dry matter) wasachieved These extrudates were ground sieved(08 mm) and packed in hermetically sealed plastic bagsand stored in the dark at 4 degC until analysis
Nixtamalisation process
One-kilogram lots of blue maize were nixtamalisedusing two different calcium solutions One lot wascooked in a solution of 1 Ca(OH)2 and the other wascooked in a solution of 295 C6H10O6Ca in a 13maizesolution ratio at 90 degC for 40 min followed by15 h of steeping The cooking liquor (nejayote) wasdiscarded and the cooked grain (nixtamal) was washedtwice with water to remove excess Ca(OH)2 orC6H10O6Ca The nixtamal was ground in a stone mill(FUMASA Mexico) and dried using a flash dryer withan input temperature of 295 degC and an output tempera-ture of 90 degC The dehydrated flours were groundsieved (08 mm) and packed in hermetically sealed plas-tic bags and stored in the dark at 4 degC until analysis

pHThe pH value was determined by the standard AACC(2000) method using a pH meter (Corning PinnacleCorning Inc New York) calibrated with standardbuffers The analysis was carried out in triplicate
Functional properties of blue maize flours
Expansion indexThe expansion index (EI) was calculated for 20 sam-ples by dividing the average diameter of the extrudedproducts by the internal diameter of the extruder dienozzle (Balandran-Quintana et al 1998 Zazueta-Morales et al 2002)
Bulk densityBulk density (BD) was determined by pouring theground extrudate (4060 mesh) into a cylindricalcontainer scraping off excess extrudate and dividingthe net weight of the powder by the volume of thecontainer (Moreyra amp Peleg 1981) Bulk density wasexpressed in kilograms per litre (kg L1) The analysiswas done in triplicate and mean values were reported
Water absorption and water solubility indexesThe water absorption index (WAI) and water solubil-ity index (WSI) were determined in triplicate followingthe procedures described by Anderson et al (1969)and were expressed as percentage The methods mea-sure the quantity of water incorporated in the flourand also the soluble solids dissolved in water at 30 degCSamples were weighed (25 g) into plastic tubes andmixed with 30 mL of distilled water The samples weremanually shaken the slurries were centrifuged for10 min at 3200 g (Thermo IEC model CL3-R USA)and the supernatant was decanted into preweighedporcelain capsules Capsules were dried for 24 h at105 degC and weighed The gel remaining in the tubesafter decanting the supernatant was weighed The ratiobetween gel-forming solids and soluble solids was mea-sured as grams of water per gram of flour
Physical properties of blue maize flours
Thermal properties of blue maize extruded floursThe gelatinisation temperature and enthalpy of starchgelatinisation were determined by differential scanningcalorimetry following the method described by Ruiz-Gutierrez et al (2011) Two milligrams of flour wasplaced in a pan with 20 lL of distilled water The panwas sealed hermetically an empty pan was used as areference The calorimeter from TA Instruments (Q-200Crawley UK) with a program of 30 degC to 110 degC and
a temperature ramp of 5 degC min1 was used The ther-mograms obtained were analysed with Universal Analy-sis software (TA Instruments Crawley UK) Thestarch gelatinisation onset temperature (To) peak tem-perature (Tp) and end temperature (Te) were obtainedfrom the thermograms The gelatinisation enthalpy(DHg) was obtained by integrating the area under thecurve Each determination was done in duplicate
Pasting properties of the extruded floursThe apparent viscosity of the flours was measuredaccording to the method described by Zazueta-Morales et al (2002) using a Rapid Visco Analyser(RVA SUPER 4 Newport Scientific Sydney Austra-lia) Flour sample suspensions were prepared by weigh-ing 4 g of extrudates milled and dried (50 2 degC 12h) with 475 to 85 moisture content into an RVAcanister and individually adjusting each sample to thetotal weight of 28 g using distilled water The rotatingpaddles were held at 50 degC for 2 min to stabilise thetemperature and ensure uniform dispersion thenheated to 92 degC at 56 degC min1 which was held con-stant for 5 min then cooled to 50 degC at the same rateand finally held at 50 degC for 1 min The viscosity at92 degC (V92) minimum viscosity (MinV or lowest vis-cosity at the end of heating constant period at 92 degC)and final viscosity (FinV or maximum viscosityattained during cooling to or holding at 50 degC) wererecorded The total setback viscosity (final minus mini-mum viscosity) was calculated from these parametervalues The viscosity with RVA was obtained in RVUunits (1 RVU = 10 centipoises) Two determinations ofeach treatment were performed
Scanning electron microscopyFlour samples with particle sizes lt015 mm and mois-ture content of 1 were stuck to stubs and coatedwith a gold layer in a high vacuum using a Dentonvacuum evaporator (Desk II) set to a pressure of7031 9 102 kg cm2 The samples were examinedusing a scanning electron microscope (JSM-5800LVJEOL Akishima Japan) equipped with a secondaryelectron detector at an acceleration rate of 10 kV
Statistical analysis
The results were analysed by nested ANOVA wherefactor A was the calcium source [Ca(OH)2 andC6H10O6Ca] and factor B that was nested in A wasthe concentration of each calcium source [01 02and 03 for Ca(OH)2 and 03 06 and 09 forC6H10O6Ca] In addition a contrast analysis of themean differences between the results for EF and NFwas performed Significance was defined as P lt 005using SAS software version 92 (2007) (SAS InstituteInc Cary NC)

Results and discussion
Blue maize characterisation
The proximate composition of blue maize is showedin Table 1 The pH test weight and the flotationindex were 587 7333 272 kg hL1 and 9466 057 kg hL1 respectively which were higher thanthose of other genotypes such as the white and yel-low hybrids (Gutierrez-Uribe et al 2010) Theseproperties are related to endosperm texture Betranet al (2000) indicated that most of blue maizegenotypes possess a floury endosperm that requiresless cooking time
Expansion index
The EI of the extruded blue maize (Table 2) was notaffected (P gt 005) by the calcium source or concentra-tion However the EI of the EF prepared without acalcium source was greater and significantly differentfrom that of the extruded prepared with either calciumsource thus a lower calcium concentration resulted ina higher EI The EI values for extruded flours indicateto some extent the starch damage caused by the extru-sion process which could result in sticky masa andtortilla with certain hardness degree but with
application perhaps for the elaboration of maizesnacks Zazueta-Morales et al (2002) and Martınez-Bustos et al (1998) reported similar EI results formaize extrudates The decrease in the EI can be attrib-uted to the damage in the starch molecules caused byCa(OH)2 Kervinen et al (1984) reported that bothacid and alkaline treatments during the extrusion pro-cess significantly decreased the molecular weight of thestarch decreasing its expansion The starchndashcalciumcomplexes restrict the extent of the flash-off of internalmoisture after the extrudate emerges from the die(Zazueta-Morales et al 2002) because the calciumions electrostatically bind to the OH groups of thestarch making the molecule more compact (Camire ampClydesdale 1981)
Bulk density
Despite that the BD values are similar some significantdifferences can be seen (Table 2) Contrast analysisrevealed that the BD for EF was slightly increased ascalcium hydroxide concentration increases NF withboth calcium sources showed similar BD values to theEF with added calcium being different to the EF con-trol which showed the lowest BD value Thus higherconcentration of Ca(OH)2 induced an increase in theBD values This effect can be related to the EI obtainedwhere a high EI results in a low BD of the EF preparedwithout calcium source These results are similar tothose reported by Martınez-Bustos et al (1998) andZazueta-Morales et al (2001) for maize instant floursMost BD values for EF match the values obtained forNF suggesting that EF could be used for tortillas(slightly harder) as well as for maize snacks production

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

Summary The effects of different concentrations of calcium hydroxide [Ca(OH)2] and calcium lactate [C6H10O6Ca]
on the functional and physical properties of extruded (EF) and nixtamalised (NF) blue maize flours were
evaluated Calcium source and concentration showed no significant effects on the EF expansion index
The water absorption index (WAI) of EF decreased as the concentrations of both calcium sources
increased and NF with C6H10O6Ca had the lowest WAI The thermal and pasting properties of NFs were
higher than those of EF NF with C6H10O6Ca showed the highest final viscosity (FinV) indicating less
damage to the starch granules and this was correlated with microscopic analysis In contrast the FinV of
EFs was significantly affected by calcium source and concentration Extrusion with 03 and nixtamalisa-
tion at 295 of C6H10O6Ca yielded high WAI value and the best rheological properties in maize flour
respectively These results suggest the use of C6H10O6Ca in extrusion or nixtamalisation to produce blue
maize flours for tortilla or snacks with antioxidants
Keywords Blue maize calcium hydroxide calcium lactate extrusion nixtamalisation rheological properties
Introduction
Pigmented maize has received increased attention inthe last decade because of the consumer demand forhealthy nixtamalised corn products such as tortillasand tacos Anthocyanins give colour to the grains andare found mainly in the pericarp andor the aleuronelayer (Salinas-Moreno et al 1999) They have nutra-ceutical properties with possible health benefits (Leeet al 2005) During nixtamalisation the maize iscooked and steeped in calcium hydroxide [Ca(OH)2]solution to obtain nixtamal The pericarp is softenedand removed which allows calcium and water to dif-fuse into the grain causing physicochemical changes(Steffe amp Singh 1980) in starch protein and germthese changes affect the organoleptic properties of
masa (dough) flour tortillas and other nixtamalisedmaize products Blue maize nixtamalisation has thedrawback that with the removal of pericarp anthocya-nin and polyphenolic derivate compounds are also lostby leaching and instability at high pH values (Pflugfel-der et al 1988 Cortes-Gomez et al 2006) resultingin the varying colours of nixtamalised products Onthe other hand the extrusion cooking process has beenused to manufacture instant maize flour (Mensah-Agyapong amp Horner 1992 Gomez Aldapa et al1996) During this process the Ca(OH)2 addition isnecessary to provoke the physicochemical changes inthe starch to obtain flour masa and tortillas with simi-lar characteristics to nixtamalised maize flour besidesthat lime represents a calcium source to improve thenutritional products valueThe effects of lime during nixtamalisation and extru-

characteristics of blue maize flour have been reported(Cortes-Gomez et al 2005 Del Pozo-Insfran et al2007 Aguayo-Rojas et al 2012) However the use ofother calcium sources that generate less alkaline solu-tions for processing blue maize has not reported Pre-vious studies have shown that less alkaline conditionsdecrease the average molecular weight of starch with-out affecting the structural characteristics of the prod-uct (Kervinen et al 1984 Pan et al 1998) Thestructural characteristics of maize products have beenrelated to calciumndashstarch interaction during gelatinisa-tion studies and processing (Tovar et al 2004 Cortes-Gomez et al 2005) Robles et al (1988) and Mendezet al (2006) found that the calciumndashstarch interactionafter nixtamalisation causes an increase in the gelatini-sation temperature and enthalpy of starch Thechanges that are produced in the starch granules maybe evaluated through rheological functional and tex-tural properties of the final products (Robles et al1988 Mondragon et al 2004 Mendez et al 2006)The effect of alkalinity and calcium concentration onthe physicochemical and functional properties on theextruded and nixtamalised flour has been evaluated inprevious studies (Zazueta-Morales et al 2002 Mora-Rochın et al 2010 Aguayo-Rojas et al 2012)Although Ca(OH)2 has been used traditionally othercombined or individual compounds with or withoutcalcium have been studied in nixtamalisation (Robleset al 1988 Maya et al 2010) Ruiz-Gutierrez et al(2011) reported that white maize nixtamalisation withcalcium lactate [C6H10O6Ca] resulted in tortillas withgood colour and texture The use of C6H10O6Ca fornixtamalisation or extrusion in blue maize has notbeen reported and it can represent an advantagebecause it produces near-neutral pH values whichwould minimise the degradation of antioxidants(Brouillard 1982 Rein 2005) and less damage in thestarch improving the physical and chemical propertiesof masa tortilla and related products The novel con-tribution of this investigation allows the researcher toevaluate the effect of the calcium lactate on the physi-cal properties on the blue maize flour that had notresearched before The aim of this study was to evalu-ate the effect of Ca(OH)2 and C6H10O6Ca concentra-tions on the functional and physical properties ofextruded and nixtamalised blue maize flours
Materials and methods
Materials
Blue maize (Zea mays L) from Babicora ChihuahuaMexico was used Calcium hydroxide [Ca(OH)2] andcalcium lactate [C6H10O6Ca] were used as the calciumsources Proximal analysis was performed for maizecharacterisation Test weight (Method 14-40 AACC
2000) and flotation index (Salinas et al 1992) werealso determined
Extrusion process
Blue maize kernel was milled in a hammer mill (Pulvexmodel 200 Mexico) with a 5-mm sieve to obtain 2- to3-mm grits and fine powder Lots (850 g) of milled bluemaize were mixed separately with different concentra-tions of Ca(OH)2 (01 02 and 03) andC6H10O6Ca (03 06 and 09) Then each lot wasmoisturised with water to reach a moisture content of30 A lot without added calcium was prepared simi-larly to serve as a control (EF control) Each lot waspacked in a polyethylene bag stored for 14 h at 4 degCand then extruded in a single-screw extruder (CINVE-STAV-IPN Queretaro Mexico) The extruder had abarrel (length 428 mm diameter 25 mm) with threeindependent electrically heated zones Screw compres-sion ratio was 11 die diameter was 4 mm and thesystem was operated under a 30-Hz speed screw and aconstant feed rate (30 g min1) which was kept con-stant Processing temperatures in the different zones(feed compression and die) were kept constant at50 degC 70 degC and 80 degC respectively During eachexperimental run the extruder was operated at a steadystate for each condition set This condition was moni-tored and controlled with constant amperage Theextrudate samples were collected and dried at 45 degC for48 h in forced-air convection oven until a moisturecontent of 009 to 011 g kg1 dm (dry matter) wasachieved These extrudates were ground sieved(08 mm) and packed in hermetically sealed plastic bagsand stored in the dark at 4 degC until analysis
Nixtamalisation process
One-kilogram lots of blue maize were nixtamalisedusing two different calcium solutions One lot wascooked in a solution of 1 Ca(OH)2 and the other wascooked in a solution of 295 C6H10O6Ca in a 13maizesolution ratio at 90 degC for 40 min followed by15 h of steeping The cooking liquor (nejayote) wasdiscarded and the cooked grain (nixtamal) was washedtwice with water to remove excess Ca(OH)2 orC6H10O6Ca The nixtamal was ground in a stone mill(FUMASA Mexico) and dried using a flash dryer withan input temperature of 295 degC and an output tempera-ture of 90 degC The dehydrated flours were groundsieved (08 mm) and packed in hermetically sealed plas-tic bags and stored in the dark at 4 degC until analysis

pHThe pH value was determined by the standard AACC(2000) method using a pH meter (Corning PinnacleCorning Inc New York) calibrated with standardbuffers The analysis was carried out in triplicate
Functional properties of blue maize flours
Expansion indexThe expansion index (EI) was calculated for 20 sam-ples by dividing the average diameter of the extrudedproducts by the internal diameter of the extruder dienozzle (Balandran-Quintana et al 1998 Zazueta-Morales et al 2002)
Bulk densityBulk density (BD) was determined by pouring theground extrudate (4060 mesh) into a cylindricalcontainer scraping off excess extrudate and dividingthe net weight of the powder by the volume of thecontainer (Moreyra amp Peleg 1981) Bulk density wasexpressed in kilograms per litre (kg L1) The analysiswas done in triplicate and mean values were reported
Water absorption and water solubility indexesThe water absorption index (WAI) and water solubil-ity index (WSI) were determined in triplicate followingthe procedures described by Anderson et al (1969)and were expressed as percentage The methods mea-sure the quantity of water incorporated in the flourand also the soluble solids dissolved in water at 30 degCSamples were weighed (25 g) into plastic tubes andmixed with 30 mL of distilled water The samples weremanually shaken the slurries were centrifuged for10 min at 3200 g (Thermo IEC model CL3-R USA)and the supernatant was decanted into preweighedporcelain capsules Capsules were dried for 24 h at105 degC and weighed The gel remaining in the tubesafter decanting the supernatant was weighed The ratiobetween gel-forming solids and soluble solids was mea-sured as grams of water per gram of flour
Physical properties of blue maize flours
Thermal properties of blue maize extruded floursThe gelatinisation temperature and enthalpy of starchgelatinisation were determined by differential scanningcalorimetry following the method described by Ruiz-Gutierrez et al (2011) Two milligrams of flour wasplaced in a pan with 20 lL of distilled water The panwas sealed hermetically an empty pan was used as areference The calorimeter from TA Instruments (Q-200Crawley UK) with a program of 30 degC to 110 degC and
a temperature ramp of 5 degC min1 was used The ther-mograms obtained were analysed with Universal Analy-sis software (TA Instruments Crawley UK) Thestarch gelatinisation onset temperature (To) peak tem-perature (Tp) and end temperature (Te) were obtainedfrom the thermograms The gelatinisation enthalpy(DHg) was obtained by integrating the area under thecurve Each determination was done in duplicate
Pasting properties of the extruded floursThe apparent viscosity of the flours was measuredaccording to the method described by Zazueta-Morales et al (2002) using a Rapid Visco Analyser(RVA SUPER 4 Newport Scientific Sydney Austra-lia) Flour sample suspensions were prepared by weigh-ing 4 g of extrudates milled and dried (50 2 degC 12h) with 475 to 85 moisture content into an RVAcanister and individually adjusting each sample to thetotal weight of 28 g using distilled water The rotatingpaddles were held at 50 degC for 2 min to stabilise thetemperature and ensure uniform dispersion thenheated to 92 degC at 56 degC min1 which was held con-stant for 5 min then cooled to 50 degC at the same rateand finally held at 50 degC for 1 min The viscosity at92 degC (V92) minimum viscosity (MinV or lowest vis-cosity at the end of heating constant period at 92 degC)and final viscosity (FinV or maximum viscosityattained during cooling to or holding at 50 degC) wererecorded The total setback viscosity (final minus mini-mum viscosity) was calculated from these parametervalues The viscosity with RVA was obtained in RVUunits (1 RVU = 10 centipoises) Two determinations ofeach treatment were performed
Scanning electron microscopyFlour samples with particle sizes lt015 mm and mois-ture content of 1 were stuck to stubs and coatedwith a gold layer in a high vacuum using a Dentonvacuum evaporator (Desk II) set to a pressure of7031 9 102 kg cm2 The samples were examinedusing a scanning electron microscope (JSM-5800LVJEOL Akishima Japan) equipped with a secondaryelectron detector at an acceleration rate of 10 kV
Statistical analysis
The results were analysed by nested ANOVA wherefactor A was the calcium source [Ca(OH)2 andC6H10O6Ca] and factor B that was nested in A wasthe concentration of each calcium source [01 02and 03 for Ca(OH)2 and 03 06 and 09 forC6H10O6Ca] In addition a contrast analysis of themean differences between the results for EF and NFwas performed Significance was defined as P lt 005using SAS software version 92 (2007) (SAS InstituteInc Cary NC)

Results and discussion
Blue maize characterisation
The proximate composition of blue maize is showedin Table 1 The pH test weight and the flotationindex were 587 7333 272 kg hL1 and 9466 057 kg hL1 respectively which were higher thanthose of other genotypes such as the white and yel-low hybrids (Gutierrez-Uribe et al 2010) Theseproperties are related to endosperm texture Betranet al (2000) indicated that most of blue maizegenotypes possess a floury endosperm that requiresless cooking time
Expansion index
The EI of the extruded blue maize (Table 2) was notaffected (P gt 005) by the calcium source or concentra-tion However the EI of the EF prepared without acalcium source was greater and significantly differentfrom that of the extruded prepared with either calciumsource thus a lower calcium concentration resulted ina higher EI The EI values for extruded flours indicateto some extent the starch damage caused by the extru-sion process which could result in sticky masa andtortilla with certain hardness degree but with
application perhaps for the elaboration of maizesnacks Zazueta-Morales et al (2002) and Martınez-Bustos et al (1998) reported similar EI results formaize extrudates The decrease in the EI can be attrib-uted to the damage in the starch molecules caused byCa(OH)2 Kervinen et al (1984) reported that bothacid and alkaline treatments during the extrusion pro-cess significantly decreased the molecular weight of thestarch decreasing its expansion The starchndashcalciumcomplexes restrict the extent of the flash-off of internalmoisture after the extrudate emerges from the die(Zazueta-Morales et al 2002) because the calciumions electrostatically bind to the OH groups of thestarch making the molecule more compact (Camire ampClydesdale 1981)
Bulk density
Despite that the BD values are similar some significantdifferences can be seen (Table 2) Contrast analysisrevealed that the BD for EF was slightly increased ascalcium hydroxide concentration increases NF withboth calcium sources showed similar BD values to theEF with added calcium being different to the EF con-trol which showed the lowest BD value Thus higherconcentration of Ca(OH)2 induced an increase in theBD values This effect can be related to the EI obtainedwhere a high EI results in a low BD of the EF preparedwithout calcium source These results are similar tothose reported by Martınez-Bustos et al (1998) andZazueta-Morales et al (2001) for maize instant floursMost BD values for EF match the values obtained forNF suggesting that EF could be used for tortillas(slightly harder) as well as for maize snacks production

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

characteristics of blue maize flour have been reported(Cortes-Gomez et al 2005 Del Pozo-Insfran et al2007 Aguayo-Rojas et al 2012) However the use ofother calcium sources that generate less alkaline solu-tions for processing blue maize has not reported Pre-vious studies have shown that less alkaline conditionsdecrease the average molecular weight of starch with-out affecting the structural characteristics of the prod-uct (Kervinen et al 1984 Pan et al 1998) Thestructural characteristics of maize products have beenrelated to calciumndashstarch interaction during gelatinisa-tion studies and processing (Tovar et al 2004 Cortes-Gomez et al 2005) Robles et al (1988) and Mendezet al (2006) found that the calciumndashstarch interactionafter nixtamalisation causes an increase in the gelatini-sation temperature and enthalpy of starch Thechanges that are produced in the starch granules maybe evaluated through rheological functional and tex-tural properties of the final products (Robles et al1988 Mondragon et al 2004 Mendez et al 2006)The effect of alkalinity and calcium concentration onthe physicochemical and functional properties on theextruded and nixtamalised flour has been evaluated inprevious studies (Zazueta-Morales et al 2002 Mora-Rochın et al 2010 Aguayo-Rojas et al 2012)Although Ca(OH)2 has been used traditionally othercombined or individual compounds with or withoutcalcium have been studied in nixtamalisation (Robleset al 1988 Maya et al 2010) Ruiz-Gutierrez et al(2011) reported that white maize nixtamalisation withcalcium lactate [C6H10O6Ca] resulted in tortillas withgood colour and texture The use of C6H10O6Ca fornixtamalisation or extrusion in blue maize has notbeen reported and it can represent an advantagebecause it produces near-neutral pH values whichwould minimise the degradation of antioxidants(Brouillard 1982 Rein 2005) and less damage in thestarch improving the physical and chemical propertiesof masa tortilla and related products The novel con-tribution of this investigation allows the researcher toevaluate the effect of the calcium lactate on the physi-cal properties on the blue maize flour that had notresearched before The aim of this study was to evalu-ate the effect of Ca(OH)2 and C6H10O6Ca concentra-tions on the functional and physical properties ofextruded and nixtamalised blue maize flours
Materials and methods
Materials
Blue maize (Zea mays L) from Babicora ChihuahuaMexico was used Calcium hydroxide [Ca(OH)2] andcalcium lactate [C6H10O6Ca] were used as the calciumsources Proximal analysis was performed for maizecharacterisation Test weight (Method 14-40 AACC
2000) and flotation index (Salinas et al 1992) werealso determined
Extrusion process
Blue maize kernel was milled in a hammer mill (Pulvexmodel 200 Mexico) with a 5-mm sieve to obtain 2- to3-mm grits and fine powder Lots (850 g) of milled bluemaize were mixed separately with different concentra-tions of Ca(OH)2 (01 02 and 03) andC6H10O6Ca (03 06 and 09) Then each lot wasmoisturised with water to reach a moisture content of30 A lot without added calcium was prepared simi-larly to serve as a control (EF control) Each lot waspacked in a polyethylene bag stored for 14 h at 4 degCand then extruded in a single-screw extruder (CINVE-STAV-IPN Queretaro Mexico) The extruder had abarrel (length 428 mm diameter 25 mm) with threeindependent electrically heated zones Screw compres-sion ratio was 11 die diameter was 4 mm and thesystem was operated under a 30-Hz speed screw and aconstant feed rate (30 g min1) which was kept con-stant Processing temperatures in the different zones(feed compression and die) were kept constant at50 degC 70 degC and 80 degC respectively During eachexperimental run the extruder was operated at a steadystate for each condition set This condition was moni-tored and controlled with constant amperage Theextrudate samples were collected and dried at 45 degC for48 h in forced-air convection oven until a moisturecontent of 009 to 011 g kg1 dm (dry matter) wasachieved These extrudates were ground sieved(08 mm) and packed in hermetically sealed plastic bagsand stored in the dark at 4 degC until analysis
Nixtamalisation process
One-kilogram lots of blue maize were nixtamalisedusing two different calcium solutions One lot wascooked in a solution of 1 Ca(OH)2 and the other wascooked in a solution of 295 C6H10O6Ca in a 13maizesolution ratio at 90 degC for 40 min followed by15 h of steeping The cooking liquor (nejayote) wasdiscarded and the cooked grain (nixtamal) was washedtwice with water to remove excess Ca(OH)2 orC6H10O6Ca The nixtamal was ground in a stone mill(FUMASA Mexico) and dried using a flash dryer withan input temperature of 295 degC and an output tempera-ture of 90 degC The dehydrated flours were groundsieved (08 mm) and packed in hermetically sealed plas-tic bags and stored in the dark at 4 degC until analysis

(1998) methods 95002 96052 92039 96209 and92303 respectively
pHThe pH value was determined by the standard AACC(2000) method using a pH meter (Corning PinnacleCorning Inc New York) calibrated with standardbuffers The analysis was carried out in triplicate
Functional properties of blue maize flours
Expansion indexThe expansion index (EI) was calculated for 20 sam-ples by dividing the average diameter of the extrudedproducts by the internal diameter of the extruder dienozzle (Balandran-Quintana et al 1998 Zazueta-Morales et al 2002)
Bulk densityBulk density (BD) was determined by pouring theground extrudate (4060 mesh) into a cylindricalcontainer scraping off excess extrudate and dividingthe net weight of the powder by the volume of thecontainer (Moreyra amp Peleg 1981) Bulk density wasexpressed in kilograms per litre (kg L1) The analysiswas done in triplicate and mean values were reported
Water absorption and water solubility indexesThe water absorption index (WAI) and water solubil-ity index (WSI) were determined in triplicate followingthe procedures described by Anderson et al (1969)and were expressed as percentage The methods mea-sure the quantity of water incorporated in the flourand also the soluble solids dissolved in water at 30 degCSamples were weighed (25 g) into plastic tubes andmixed with 30 mL of distilled water The samples weremanually shaken the slurries were centrifuged for10 min at 3200 g (Thermo IEC model CL3-R USA)and the supernatant was decanted into preweighedporcelain capsules Capsules were dried for 24 h at105 degC and weighed The gel remaining in the tubesafter decanting the supernatant was weighed The ratiobetween gel-forming solids and soluble solids was mea-sured as grams of water per gram of flour
Physical properties of blue maize flours
Thermal properties of blue maize extruded floursThe gelatinisation temperature and enthalpy of starchgelatinisation were determined by differential scanningcalorimetry following the method described by Ruiz-Gutierrez et al (2011) Two milligrams of flour wasplaced in a pan with 20 lL of distilled water The panwas sealed hermetically an empty pan was used as areference The calorimeter from TA Instruments (Q-200Crawley UK) with a program of 30 degC to 110 degC and
a temperature ramp of 5 degC min1 was used The ther-mograms obtained were analysed with Universal Analy-sis software (TA Instruments Crawley UK) Thestarch gelatinisation onset temperature (To) peak tem-perature (Tp) and end temperature (Te) were obtainedfrom the thermograms The gelatinisation enthalpy(DHg) was obtained by integrating the area under thecurve Each determination was done in duplicate
Pasting properties of the extruded floursThe apparent viscosity of the flours was measuredaccording to the method described by Zazueta-Morales et al (2002) using a Rapid Visco Analyser(RVA SUPER 4 Newport Scientific Sydney Austra-lia) Flour sample suspensions were prepared by weigh-ing 4 g of extrudates milled and dried (50 2 degC 12h) with 475 to 85 moisture content into an RVAcanister and individually adjusting each sample to thetotal weight of 28 g using distilled water The rotatingpaddles were held at 50 degC for 2 min to stabilise thetemperature and ensure uniform dispersion thenheated to 92 degC at 56 degC min1 which was held con-stant for 5 min then cooled to 50 degC at the same rateand finally held at 50 degC for 1 min The viscosity at92 degC (V92) minimum viscosity (MinV or lowest vis-cosity at the end of heating constant period at 92 degC)and final viscosity (FinV or maximum viscosityattained during cooling to or holding at 50 degC) wererecorded The total setback viscosity (final minus mini-mum viscosity) was calculated from these parametervalues The viscosity with RVA was obtained in RVUunits (1 RVU = 10 centipoises) Two determinations ofeach treatment were performed
Scanning electron microscopyFlour samples with particle sizes lt015 mm and mois-ture content of 1 were stuck to stubs and coatedwith a gold layer in a high vacuum using a Dentonvacuum evaporator (Desk II) set to a pressure of7031 9 102 kg cm2 The samples were examinedusing a scanning electron microscope (JSM-5800LVJEOL Akishima Japan) equipped with a secondaryelectron detector at an acceleration rate of 10 kV
Statistical analysis
The results were analysed by nested ANOVA wherefactor A was the calcium source [Ca(OH)2 andC6H10O6Ca] and factor B that was nested in A wasthe concentration of each calcium source [01 02and 03 for Ca(OH)2 and 03 06 and 09 forC6H10O6Ca] In addition a contrast analysis of themean differences between the results for EF and NFwas performed Significance was defined as P lt 005using SAS software version 92 (2007) (SAS InstituteInc Cary NC)

Results and discussion
Blue maize characterisation
The proximate composition of blue maize is showedin Table 1 The pH test weight and the flotationindex were 587 7333 272 kg hL1 and 9466 057 kg hL1 respectively which were higher thanthose of other genotypes such as the white and yel-low hybrids (Gutierrez-Uribe et al 2010) Theseproperties are related to endosperm texture Betranet al (2000) indicated that most of blue maizegenotypes possess a floury endosperm that requiresless cooking time
Expansion index
The EI of the extruded blue maize (Table 2) was notaffected (P gt 005) by the calcium source or concentra-tion However the EI of the EF prepared without acalcium source was greater and significantly differentfrom that of the extruded prepared with either calciumsource thus a lower calcium concentration resulted ina higher EI The EI values for extruded flours indicateto some extent the starch damage caused by the extru-sion process which could result in sticky masa andtortilla with certain hardness degree but with
application perhaps for the elaboration of maizesnacks Zazueta-Morales et al (2002) and Martınez-Bustos et al (1998) reported similar EI results formaize extrudates The decrease in the EI can be attrib-uted to the damage in the starch molecules caused byCa(OH)2 Kervinen et al (1984) reported that bothacid and alkaline treatments during the extrusion pro-cess significantly decreased the molecular weight of thestarch decreasing its expansion The starchndashcalciumcomplexes restrict the extent of the flash-off of internalmoisture after the extrudate emerges from the die(Zazueta-Morales et al 2002) because the calciumions electrostatically bind to the OH groups of thestarch making the molecule more compact (Camire ampClydesdale 1981)
Bulk density
Despite that the BD values are similar some significantdifferences can be seen (Table 2) Contrast analysisrevealed that the BD for EF was slightly increased ascalcium hydroxide concentration increases NF withboth calcium sources showed similar BD values to theEF with added calcium being different to the EF con-trol which showed the lowest BD value Thus higherconcentration of Ca(OH)2 induced an increase in theBD values This effect can be related to the EI obtainedwhere a high EI results in a low BD of the EF preparedwithout calcium source These results are similar tothose reported by Martınez-Bustos et al (1998) andZazueta-Morales et al (2001) for maize instant floursMost BD values for EF match the values obtained forNF suggesting that EF could be used for tortillas(slightly harder) as well as for maize snacks production
Water absorption index
The WAI of the blue maize EF (Table 2) was affected(P lt 005) by both calcium sources and their

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

(1998) methods 95002 96052 92039 96209 and92303 respectively
pHThe pH value was determined by the standard AACC(2000) method using a pH meter (Corning PinnacleCorning Inc New York) calibrated with standardbuffers The analysis was carried out in triplicate
Functional properties of blue maize flours
Expansion indexThe expansion index (EI) was calculated for 20 sam-ples by dividing the average diameter of the extrudedproducts by the internal diameter of the extruder dienozzle (Balandran-Quintana et al 1998 Zazueta-Morales et al 2002)
Bulk densityBulk density (BD) was determined by pouring theground extrudate (4060 mesh) into a cylindricalcontainer scraping off excess extrudate and dividingthe net weight of the powder by the volume of thecontainer (Moreyra amp Peleg 1981) Bulk density wasexpressed in kilograms per litre (kg L1) The analysiswas done in triplicate and mean values were reported
Water absorption and water solubility indexesThe water absorption index (WAI) and water solubil-ity index (WSI) were determined in triplicate followingthe procedures described by Anderson et al (1969)and were expressed as percentage The methods mea-sure the quantity of water incorporated in the flourand also the soluble solids dissolved in water at 30 degCSamples were weighed (25 g) into plastic tubes andmixed with 30 mL of distilled water The samples weremanually shaken the slurries were centrifuged for10 min at 3200 g (Thermo IEC model CL3-R USA)and the supernatant was decanted into preweighedporcelain capsules Capsules were dried for 24 h at105 degC and weighed The gel remaining in the tubesafter decanting the supernatant was weighed The ratiobetween gel-forming solids and soluble solids was mea-sured as grams of water per gram of flour
Physical properties of blue maize flours
Thermal properties of blue maize extruded floursThe gelatinisation temperature and enthalpy of starchgelatinisation were determined by differential scanningcalorimetry following the method described by Ruiz-Gutierrez et al (2011) Two milligrams of flour wasplaced in a pan with 20 lL of distilled water The panwas sealed hermetically an empty pan was used as areference The calorimeter from TA Instruments (Q-200Crawley UK) with a program of 30 degC to 110 degC and
a temperature ramp of 5 degC min1 was used The ther-mograms obtained were analysed with Universal Analy-sis software (TA Instruments Crawley UK) Thestarch gelatinisation onset temperature (To) peak tem-perature (Tp) and end temperature (Te) were obtainedfrom the thermograms The gelatinisation enthalpy(DHg) was obtained by integrating the area under thecurve Each determination was done in duplicate
Pasting properties of the extruded floursThe apparent viscosity of the flours was measuredaccording to the method described by Zazueta-Morales et al (2002) using a Rapid Visco Analyser(RVA SUPER 4 Newport Scientific Sydney Austra-lia) Flour sample suspensions were prepared by weigh-ing 4 g of extrudates milled and dried (50 2 degC 12h) with 475 to 85 moisture content into an RVAcanister and individually adjusting each sample to thetotal weight of 28 g using distilled water The rotatingpaddles were held at 50 degC for 2 min to stabilise thetemperature and ensure uniform dispersion thenheated to 92 degC at 56 degC min1 which was held con-stant for 5 min then cooled to 50 degC at the same rateand finally held at 50 degC for 1 min The viscosity at92 degC (V92) minimum viscosity (MinV or lowest vis-cosity at the end of heating constant period at 92 degC)and final viscosity (FinV or maximum viscosityattained during cooling to or holding at 50 degC) wererecorded The total setback viscosity (final minus mini-mum viscosity) was calculated from these parametervalues The viscosity with RVA was obtained in RVUunits (1 RVU = 10 centipoises) Two determinations ofeach treatment were performed
Scanning electron microscopyFlour samples with particle sizes lt015 mm and mois-ture content of 1 were stuck to stubs and coatedwith a gold layer in a high vacuum using a Dentonvacuum evaporator (Desk II) set to a pressure of7031 9 102 kg cm2 The samples were examinedusing a scanning electron microscope (JSM-5800LVJEOL Akishima Japan) equipped with a secondaryelectron detector at an acceleration rate of 10 kV
Statistical analysis
The results were analysed by nested ANOVA wherefactor A was the calcium source [Ca(OH)2 andC6H10O6Ca] and factor B that was nested in A wasthe concentration of each calcium source [01 02and 03 for Ca(OH)2 and 03 06 and 09 forC6H10O6Ca] In addition a contrast analysis of themean differences between the results for EF and NFwas performed Significance was defined as P lt 005using SAS software version 92 (2007) (SAS InstituteInc Cary NC)

Results and discussion
Blue maize characterisation
The proximate composition of blue maize is showedin Table 1 The pH test weight and the flotationindex were 587 7333 272 kg hL1 and 9466 057 kg hL1 respectively which were higher thanthose of other genotypes such as the white and yel-low hybrids (Gutierrez-Uribe et al 2010) Theseproperties are related to endosperm texture Betranet al (2000) indicated that most of blue maizegenotypes possess a floury endosperm that requiresless cooking time
Expansion index
The EI of the extruded blue maize (Table 2) was notaffected (P gt 005) by the calcium source or concentra-tion However the EI of the EF prepared without acalcium source was greater and significantly differentfrom that of the extruded prepared with either calciumsource thus a lower calcium concentration resulted ina higher EI The EI values for extruded flours indicateto some extent the starch damage caused by the extru-sion process which could result in sticky masa andtortilla with certain hardness degree but with
application perhaps for the elaboration of maizesnacks Zazueta-Morales et al (2002) and Martınez-Bustos et al (1998) reported similar EI results formaize extrudates The decrease in the EI can be attrib-uted to the damage in the starch molecules caused byCa(OH)2 Kervinen et al (1984) reported that bothacid and alkaline treatments during the extrusion pro-cess significantly decreased the molecular weight of thestarch decreasing its expansion The starchndashcalciumcomplexes restrict the extent of the flash-off of internalmoisture after the extrudate emerges from the die(Zazueta-Morales et al 2002) because the calciumions electrostatically bind to the OH groups of thestarch making the molecule more compact (Camire ampClydesdale 1981)
Bulk density
Despite that the BD values are similar some significantdifferences can be seen (Table 2) Contrast analysisrevealed that the BD for EF was slightly increased ascalcium hydroxide concentration increases NF withboth calcium sources showed similar BD values to theEF with added calcium being different to the EF con-trol which showed the lowest BD value Thus higherconcentration of Ca(OH)2 induced an increase in theBD values This effect can be related to the EI obtainedwhere a high EI results in a low BD of the EF preparedwithout calcium source These results are similar tothose reported by Martınez-Bustos et al (1998) andZazueta-Morales et al (2001) for maize instant floursMost BD values for EF match the values obtained forNF suggesting that EF could be used for tortillas(slightly harder) as well as for maize snacks production

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

Results and discussion
Blue maize characterisation
The proximate composition of blue maize is showedin Table 1 The pH test weight and the flotationindex were 587 7333 272 kg hL1 and 9466 057 kg hL1 respectively which were higher thanthose of other genotypes such as the white and yel-low hybrids (Gutierrez-Uribe et al 2010) Theseproperties are related to endosperm texture Betranet al (2000) indicated that most of blue maizegenotypes possess a floury endosperm that requiresless cooking time
Expansion index
The EI of the extruded blue maize (Table 2) was notaffected (P gt 005) by the calcium source or concentra-tion However the EI of the EF prepared without acalcium source was greater and significantly differentfrom that of the extruded prepared with either calciumsource thus a lower calcium concentration resulted ina higher EI The EI values for extruded flours indicateto some extent the starch damage caused by the extru-sion process which could result in sticky masa andtortilla with certain hardness degree but with
application perhaps for the elaboration of maizesnacks Zazueta-Morales et al (2002) and Martınez-Bustos et al (1998) reported similar EI results formaize extrudates The decrease in the EI can be attrib-uted to the damage in the starch molecules caused byCa(OH)2 Kervinen et al (1984) reported that bothacid and alkaline treatments during the extrusion pro-cess significantly decreased the molecular weight of thestarch decreasing its expansion The starchndashcalciumcomplexes restrict the extent of the flash-off of internalmoisture after the extrudate emerges from the die(Zazueta-Morales et al 2002) because the calciumions electrostatically bind to the OH groups of thestarch making the molecule more compact (Camire ampClydesdale 1981)
Bulk density
Despite that the BD values are similar some significantdifferences can be seen (Table 2) Contrast analysisrevealed that the BD for EF was slightly increased ascalcium hydroxide concentration increases NF withboth calcium sources showed similar BD values to theEF with added calcium being different to the EF con-trol which showed the lowest BD value Thus higherconcentration of Ca(OH)2 induced an increase in theBD values This effect can be related to the EI obtainedwhere a high EI results in a low BD of the EF preparedwithout calcium source These results are similar tothose reported by Martınez-Bustos et al (1998) andZazueta-Morales et al (2001) for maize instant floursMost BD values for EF match the values obtained forNF suggesting that EF could be used for tortillas(slightly harder) as well as for maize snacks production

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

concentrations The WAI decreased as the calciumconcentration increased (P lt 005) The highest WAIvalue for EF with calcium lactate was obtained for03 whereas the EF control exhibited the lowestWAI compared with EF calcium added Similar resultshave been reported by Zazueta-Morales et al (2002)for maize extrudates The NFs prepared using eithercalcium source displayed lower WAI and the NF withC6H10O6Ca exhibited the lowest WAI The highest val-ues of WAI in the EF can be attributed to starch dam-age caused by the extrusion cooking which could leadto cohesive and sticky masa yielding tortillas slightlyhard (Mensah-Agyapong amp Horner (1992) but withprobable applications for maize snacks
Water solubility index
The WSI of blue maize extruded flours for both cal-cium sources (Table 2) was not significantly affectedfor the different concentrations However both flourswere different (P lt 005) from the EF control TheWSI decreased slightly when the calcium concentrationof either calcium source was increased The sameobservation was reported by Arambula et al (1998)for extruded blue maize This effect could be attributedto the added Ca(OH)2-forming complexes with thestarch causing starch swelling and therefore decreasingthe WSI
Thermal properties
Table 3 shows that the starch gelatinisation tempera-tures (To Tp and Te) and gelatinisation enthalpy(DHg) values of the EFs prepared with both calciumsources at different calcium concentrations were notdifferent (P gt 005) This result is most likely due tothe strong effects of the extrusion process on the starchmolecules resulting in lower gelatinisation enthalpyvalues Similar findings were reported by Mondragonet al (2004) for nixtamalisation with different Ca(OH)2 concentrations they found no significant effectson the thermal properties of the flours
The gelatinisation enthalpy values of the NFs weresignificantly different from those of the EFs whichhad the lowest values These low gelatinisationenthalpy values indicate that there is a large amountof gelatinised starch in the EFs therefore less energyis required to gelatinise the rest of the starch (Mon-dragon et al 2004) The differences in gelatinisationenthalpy between EFs and NFs are shown in Figure 1

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

for EF The EF exhibited MinV values similar to thatof the control and different (P lt 005) from that ofboth NFs Moreover the MinV values of the two NFswere not significantly different and showed the lowestMinV values which were similar to that obtained forraw blue maize
The final viscosity (FinV) is inversely related to thedegree of starch gelatinisation Therefore processedflour that contains gelatinised starch does not developan increased viscosity whereas unprocessed flour thatcontains mainly native starches develops viscosity toits maximum capacity In this study the FinV(Table 3) was affected (P lt 005) by both calciumsources and their concentrations The FinV values of
EF increased as Ca(OH)2 concentration increasedwhereas increasing the C6H10O6Ca concentrationcaused the FinV values to decrease (Fig 2) Similarresults were reported by Mensah-Agyapong amp Horner(1992) and Zazueta-Morales et al (2002) for maizeextrusion with Ca(OH)2 This phenomenon was attrib-uted to the formation of complexes of the starch com-ponents with the calcium from the lime (Robles et al1988 Islam amp Azemi 1994 San Martın-Martınezet al 2003) For the EF prepared with C6H10O6Cathe FinV values decreased with increasing calciumsource concentration (Fig 2) most likely due to thelow ionisation of C6H10O6Ca compared with that ofCa(OH)2 which did not promote the release of Ca2+

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

ions limiting their interaction with the starch and con-sequently affecting viscosity The control EF had ahigher FinV (Fig 2) than the other EFs most likelydue to the pH effect (Table 2) of the two calciumsources on the EFs The FinV value of the NFs washigher than that of the EFs (Fig 2) The NF preparedwith C6H10O6Ca had a higher FinV value than the NFprepared with Ca(OH)2 because of less damaged starchgranules FinV value trends in the maximum peaksbetween nixtamalised and EF indicate differences inthe extent of the damage to the starch (Fig 2) It sug-gests that EF could produce cohesive and slightlysticky masa and tortillas with some degree of tough-ness Similar finding was reported by Mensah-Agya-pong amp Horner (1992)
Scanning electron microscopy
The scanning electron micrographs revealed that theEF with Ca(OH)2 and C6H10O6Ca at different
concentrations contained starch granules showingcomplete loss of structure (Fig 3) The damage thatoccurred during the extrusion process was notable inthe large numbers of flattened and sheared granulesSimilar results have been reported for corn semolina(Mercier et al 1979) corn grits (Gomez amp Aguilera1984) and corn meal extrudates (Martınez-Bustoset al 1998) These results are due to starch dextrini-sation which is the principal mechanism of starchfragmentation during the extrusion process (Gomez ampAguilera 1984) The same type of starch damage wasobserved in the control EF (Fig 3g) In contrast theNFs exhibited less damaged starch granules withspherical and polygonal shapes (Figs 3hi) Thesemorphological results were confirmed by the obtainedDHg values (Table 3) The damage to the starch byextrusion cooking process can be related with thedevelopment of cohesive and slightly adhesive masawhich could be used to obtain tortillas with somedegree of toughness suitable for snacks

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Conclusions
The use of C6H10O6Ca as an alternative source to limein extrusion and nixtamalisation of blue maize effec-tively improved the rheological properties of instantmaize flours The extrusion process severely damagedthe starch compared with nixtamalisation reducing theeffects of calcium sources on the flourrsquos physical andfunctional properties The WAI and pasting propertiesof the extruded flours were influenced by the calciumsources and their concentrations The pasting propertiesof NFs were higher than those of EFs indicating thedamaging effect of the extrusion process on the starchmolecules which was confirmed by the thermal andmicroscopic analyses NF prepared with C6H10O6Cahad higher viscosity than NF prepared with Ca(OH)2Extrusion with 03 and nixtamalisation at 295 ofC6H10O6Ca yielded high WAI value and the bestrheological properties in blue maize flour respectivelyindicating for rheological properties less damagedstarch and high viscosity values This could be relatedto the degree of cooking cohesiveness of the dough andchewiness of the final tortilla product suggesting thatthese flours could be used for the manufacture of snacksor tortillas with adequate quality characteristics Addi-tional studies are needed to evaluate the application ofthe blue corn flours in the development of maize prod-ucts costs and environmental benefits

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44

Summary The effects of red cactus pear encapsulation by spray drying using soluble fiber 21
were evaluated Cactus pear juice was mixed with 15 225 or 30 soluble fiber and 22
dried at 160 180 or 200degC The juice showed high levels of polyphenols quercetin 23
kaempferol isoharmetin betacyanins betaxanthins and antioxidant activity Increased 24
soluble fiber significantly increased pH aw water solubility index L and b Polyphenols 25
and betacyanins decrease significantly as soluble fiber increased and drying temperature 26
increased respectively Encapsulation at 160ordmC and 225 soluble fiber yielded good 27
physical properties and a higher content of bioactive compounds Microscopy analyses 28
showed capsules with a spherical shape These forms of capsules were affected by the 29
soluble fiber concentration added found more collapsed capsules when less soluble fiber 30
was added The soluble fiber utilized to encapsulate cactus pears resulted in a powder with 31
good properties that could be used as an ingredient in the food industry 32

Introduction 36
The consumer preference for tasty and healthy food products has increased in recent years 37
(1) a trend that has promoted the development of functional food In Mexico there are 38
numerous native fruits that could be considered as functional foods Among these is the 39
cactus pear which belongs to the Cactaceae family and has a diversity of forms and colors 40
Recent studies have shown that the cactus pear contains components that have beneficial 41
health effects for consumers as the flavonoids quercetin kaempferol and isoharmetin in 42
yellow and red cactus pear cultivars (2) indicating that they can delay the effects of 43
oxidative damage by stabilizing free radicals (3) Further other reports suggest that the 44
