Production & Post Harvest ScenarioProduction & Post Harvest Scenario•Agriculture contributes about 14.5% of GDP, employees 52% workforce and sustains approx over 60% of the population •India ranks second in world in production of fruits and vegetables•Post harvest losses are 3-18% amounting to Rs. 45000 crores•Low level of processing of fruits and vegetables at only 3.5% .•Food processing is employment intensive, creates 1.8 jobs directly and 6.4 indirectly for every Rs. 10 lakh investment
Better PH Management-Higher Value Addition-Lower losses
IntroductionIntroduction• The primary processing treats the produce for
changing its from as little as possible.• Can be safely transported to long distance
for fresh consumption • Safely stored as a raw material for value
added products.• Due to higher moisture the physiological
changes keep continuing even after harvest hence primary processing covers wide range of unit operations
• Proper primary processing results in volume reduction for storage and transport and hence substantially reduces the post harvest losses.
Primary Processing OperationsPrimary Processing Operations
Post harvest management aiding Value addition and Secondary agriculture.
•Pre-harvest Instruments•Curing after harvest, •Pre-cooling before storage, •Ripening•Peeling, •Decorticating, •Dehydration and •Pulping
Maturity IndicatorsMaturity Indicators
• To ensure sensory quality like flavour, colour, aroma and texture and nutritional quality of the fruit.
• To ensure an adequate post harvest shelf life of the fruit.
• To facilitate scheduling of the harvest and packing operations.
Maturity Indicating InstrumentsMaturity Indicating Instruments
•Electromagnetic Technologies The electromagnetic spectrum from longest to shortest wavelengths, radiowave, microwave, ultraviolet, visible light, infrared, X-ray and gamma-ray radiation.•Wave propagationSonic and ultrasonic waves can be transmitted, reflected, refracted or diffracted as they interact with the material.•Electrical conductivityThe concentration of volatiles within a fruit or vegetable increases as it ripens and their release to the surrounding atmosphere is responsible for the product's pleasing aroma.

Method of Determining Maturity of Method of Determining Maturity of Mango in Tree Mango in Tree
• Eating quality and postharvest shelf life of ripe mango depends on its maturity at harvest
• Change of peel color and total soluble solids (TSS) are indicative parameters to measure maturity of mango.
• A maturity index was defined based on TSS and colour values.
• The model was developed to predict maturity using colourimeter
• Colour and maturity index chart were also developed to determine maturity
• This technique can be employed to sort the mangoes at export port, big mandies and in processing plant.
CapacityAbout 100 mangoes per hour
Fruit Saving GadgetsFruit Saving Gadgets
After plucking from tree, fruit is thrown in the trough of fruit saver and collected in a box/container.
The fruits are graded on size basis at appropriate places. Smallest grade fruit is collected first and largest grade is collected in last
Pre Cooling of Fruits & VegetablesPre Cooling of Fruits & Vegetables
In addition to removal of field heat from commodities, pre-cooling also reduces bruise damage from vibration during transit and removes contaminants and microbial load on the fruit. Methods of pre-cooling •Cold air (room cooling, forced air cooling) •Cold water (hydro cooling) •Direct contact with ice (contact icing), •Evaporation of the water from produce (evaporative cooling, vacuum cooling) •Some fungicides can also be mixed with the water used in hydro cooling to prolong the shelf life
CIPHET Tomato GraderCIPHET Tomato Grader• The tomatoes roll down the pipes due to
gravity and fall immediately wherever they find the space of their diameter.
• Grades 3: 25-40 mm, 40-55 mm, 55-70 mm and > 70 mm
• The collector is inclined at 10° so that the tomatoes slide directly in crates.
• The important feature of grader is its ability to adjust the gap between the pipes and inclination of grading table and hopper.
• It can also be used for other round fruits and vegetables.
Capacity: of 325 kg/hr Overall grading efficiency: 66%.Cost: Rs.25000.00
Banana-Comb (Hand) CutterBanana-Comb (Hand) Cutter
It is an useful to de-stem the comb from the banana bunch. It replaces the use of sickle, which was much labor and time consuming. It is safe for human and banana hands and can be used for faster work. 100 to 120 banana bunches can be de-handed per hour. Saves 10 to 15 banana-fingers per bunch (i. e. 2 to 8 % reduction in cutting losses of banana fruits)
•Higher aril extraction capacity; around 5.0 quintal per hour Higher aril extraction capacity; around 5.0 quintal per hour •Aril extraction/separation efficiency is in the range of 90-94%Aril extraction/separation efficiency is in the range of 90-94%•Mechanical damage received by arils is only 1-2%Mechanical damage received by arils is only 1-2%

Capacity 10 kg/h
Aloe Vera Gel ExtractorAloe Vera Gel Extractor•Aloe vara gel should be extracted within 6 hours and processing must be completed within 36 hours.•An inner clear gel that contains 99% water and rest made of glucomannans, amino acids, lipids, sterols, vitamins etc.•The equipment capacity 200-225kg gel/h (900-1000 leaves/h) for motorised and 100kg gel/h (400-450 leaves/h) for manual machine. •The extracted gel is clean and without any physical damage.
Litchi PeelerLitchi Peeler• CIPHET Litchi peeler capacity of
60 kg/h. • Consists of two stainless steel
rollers rotating at differential speed in opposite direction with SS spikes on one roller and knurled surface on other.
• As the fruit approaches to the spikes, it pierces the peel of fruit and due to circular motion makes a cut on the peel.
• Peel is separated from the fruit due to shear developed by differential speed and knurled surface,
• The optimum peeling efficiency of the machine was about 96% with less than 4% loss of pulp.

Future PotentialFuture Potential
• Need to develop proper process protocols for primary processing and also develop crop specific machines
• Processing of fruits and vegetables to the stage of dehy, puree or pulp is a primary processing industry and need to be established in production catchment.
• There should be flexibility in operations – a combination of manual and mechanical systems but following proper sanitary and hygienic standards.
• Need to develop standards for primary processed products which in turn will increase value addition and secondary agriculture activities
