BUREAU OF INDIAN STANDARDS MANAK BHAVAN, 9 ‘BAHADUR SHAH ZAFAR MARG

Food Additives Sectional Committee, FAD 8
This-Indian Standard (First Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by the Food Additives Sectional Committee had been approved by the Food and Agriculture Division Council.
Gelatin is widely used in the food processing industry as a stabilizer, gelling agent, emulsifying agent and a crystallization inhibitor. It is also permitted as a food additive under the PFA Rules, 1955.
This standard was first published in 1970 to guide the indigenous manufacturers in making their product conform to international specifications. Considerable assistance was derived from the Pharmacopoeia of India, 1966 and the British Standard on sampling and testing gelatins in the preparation of the stan-dard. This standard is”being revised to update and align with the JECFA specification for gelatin specifically with regards to the limits for heavy metal contaminants and methods of test.
h the preparation of this standard, due consideration has been given to the Prevention of Food Adulteration Act, 1954 and the Rules, 1955 framed thereunder. Due consideration has also been given to the Standard of Weights and Measures (Packaged Commodities) Rules, 1977. However, this standard is subject to restrictions imposed under these, wherever applicable.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with 1S2: 1960 ‘Rules for rounding off numerical values (revised)’. The-number of significant places retained in the rounded off value should be the same as that of the specified va[ue in this standard.
GELATIN, FOOD GRADE — SPECIFICATION
This standard prescribes requirements and methods of sampling and test for gelatin, food grade which is also known as edible gelatin.
The following standards contain provisions which through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated “below:

Gelatin is a protein produced-by partial hydrolysis of collagen derived from skin, tendons, ligaments and bones of animals.
4.1.1 Gelatin shall be in the form of sheets, flakes, shreds or coarse to fine powder, faint yellow or amber in colour, the shade varying in depth according to particle size.
4.1.2 Itshall have a slight bouillon like odour. It is stable in air when dry, but is susceptible to microbial decomposition when moist or in solution.
Gelatin is practically insoluble in cold water but shall swell -and soften when immersed in it, gradually absorbing from 5 to 10 times its own weight of water. It is soluble in hot water; mixture of hot water and glycerin forming a jelly on cooling; and in acetic acid (approximately 5 N).
Gelatin is practically insoluble in alcohol (95 percent), in chloroform, solvent ether and fixed and volatile oils.
4.2.2 Precipitate Formation
To a solution of gelatin (1 in 100) add trinitrophenol TS or a solution of potassium bichromate (1in 15previously mixed with about one-fourth its volume of dilute hydrochloric acid, a yellow precipitate shall be formed.
To a sohtion of gelatin ( 1 in 100) add mercuric nitrate solution; a white precipitate shall be formed which develops a brick red colour on warming.
4.2.3 Development of Turbidity
To a solution (1 in 5 000) add tannic acid TS; the solutkm becomes turbid.
4.2.4 When heated with soda lime, ammonia is evolved.
4.3 The product shall also conform to the requirements given in Table 1.
4.4 The product shall be processe~ packed, stored and distributed under hygienic conditions in licensed premises (see IS 2491).
5 PACKING, STORAGE AND MARKING
The product shall be filled in ghiss containers or any other containers wjth as little airspace as possible. The containers shall be such as to preclude contamination of the contents with metals or other impurities.
The product shall be stored in a cool and dry place so as to avoid excessive exposure to heat.
