FOREWOkD
This Indian Standard wasadopted by the Bureau of Indian Standards, after the draft finalized by the
Food Additives Sectional Committee had beenapprovedby the Food and AgricultureDivisionCouncil.
With the increased production ofprocessed foods, n;lanufacturers have started addinga large Dumber
of substances, generally in small quantities, to improve the appearance, flavour, texture or storage
properties and in some cases to enhance the nutritive values of the processed food. As certain
impurities in these substances have been found to be harmful, it is necessary to have strict quality
control ofthese food additives. A series ofstandards is. therefore, being prepared by the Institution to
cover purity and identification of these substances. These standards would help in checking purity
which requires to be checked at the stage ofmanufacture, for it is extremely difficult (and in many
cases impossible) to detect the impurity once these substances have been added to theprocessedfoods.
Besides, these standards are intended to guide the indigenous manufacturers in making their product
conform to specifications that are accepted by scientists, health authorities and international bodies.
Polyglycero1esters ofinteresterified ricinoleic acids also knownas glyceran ester of condensed castor
oil fatty acids and polyglycerol esters of polycondensed fatty acids from castor oil. These are prepared
by the esterification ofpolyglycerol with condensed castor oil fatty acids.
Polyglycerol esters ofinteresterified ricinoleic acids are being permitted for use as release agents in
bakery industry and in chocolate manufacture.
The major components have the following general structure.

where the average value of-n' is about 3 and R1, R. and R. each maybe hydrogen or a linear conden
sation polymer ofricinoleic acid with itselfas follows:
where the average value of am' isbetween 5and 8.
In the preparationofthis standard the consideration has been given to the provisions of the Prevention
0/Food Adulteration. Act, 19~4 and the Rules framed thereunder and the Standards of Weights and
Measures (PackagedCommodities)Rules, 1977. However, this standard is subject to the restrictions
imposed under these Acts whereverapplicable.
Considerable assistance has been derivedfrom FAO Food and Nutrition Papers No.4 'Specification for
identity and purity ofthickening agents, anticakins agents, antimicrobials, antioxidantsand emulsifiers'
published by the JointFAO/WHO Expert Committee on Food Additives, Rome 1978.
The EEe Directive on the product which is in the draft stage has alsobeen given due consideration and
the requirements ofthis standard are aligned with the draft EEeDirectives.
For the purpose ofdeciding whether a particular requirement of this standard is complied with, the
final value, observed or calculated, expressingthe result ofa test or analysis. shall be rounded oft'in
accordance with IS 2 : 1960'Rules for rounding off numerical values ( revised)'. The number ofsigni
ficant places retained in the rounded off value should be the same as that of the specified value in this
standard.
