Dairy Products and Equipment Sectional Committee, FAD 19

FOREWORD
This Indian Standard (Fifth Revision) was adopted by the Bureau of Indian Standards, after the draft finalized
by the Dairy Products and Equipment Sectional Committee had been approved by the Food and Agriculture
Division Council.
Milk-cereal based complementary foods are mainly intended to accustom the infant’s digestive tract to solid foods.
Nutritionally, this category of foods serves as an important source of calories to meet the energy requirements
due to increased physical activity of infant. Beginning with the introduction of cereals after six months of age,
the intake is slowly increased so that by 8 months of age and onwards, nearly half of the total intake is from milk
and remaining from cereals and a variety of other foods. With such a feeding practice, milk almost completely
meets the protein requirements, while cereals and/or other foods meet the energy and satiety requirements of the
infant.
Under the Infant Milk Substitutes, Feeding Bottles and Infant Foods (Regulation of Production, Supply and
Distribution) Act, 1992, various types of foods for infants being marketed in our country have been placed under
the following two categories:
a) Infant milk substitutes, and
b) Infant foods.
‘Infant milk substitute’ means any food being marketed or otherwise represented as partial or total replacement for
mother’s milk, whereas ‘Infant Food’ means any food being marketed or otherwise represented as a complement
to mother’s milk to meet the growing nutritional needs of the infant after the age of six months and up to the age
of two years.
This standard covers the requirements for milk-cereal based complementary foods and a separate standard,
namely, IS 11536 : 2022 ‘Processed cereal based complementary foods for infants — Specification (third revision)’
exists which covers the requirements for processed cereal based complementary foods.
This standard was first published in 1960 and subsequesntly revised in 1969, 1985, 1997 and then in 2007 to
update the chemical and microbiological requirements and recommendatory list of sources of vitamin compounds
and minerals salts; and to include list of permitted food additives.
A scheme for labelling environment friendly products known as ECO-Mark was also introduced in the fourth
revision at the instance of the Ministry of Environment and Forests, Government of India. The ECO-Mark shall be
administered by the Bureau of Indian Standards (BIS) under the BIS Act, 2016 as per the Resolution No. 71 dated
20 February 1991 and No. 425 dated 28 October 1992 published in the Gazette of the Government of India. For
a product to be eligible for marking with the ECO-Mark, it shall also carry the Standard Mark of BIS for quality
besides meeting additional environment friendly (EF) requirements given in the standard, which are based on the
Gazette Notification No. GSR 624 (E) dated 6 September 1995 for labelling beverages, infant foods and processed
fruits and vegetable products as Environment Friendly Products, published in the Gazette of the Government of
India.
Amendments were later issued to IS 1656 : 2007 in November 2012 and November 2014.
This fifth revision has been brought out to harmonize the requirements of milk-cereal based complementary foods
with the Food Safety and Standards (Foods for Infant Nutrition) Regulations, 2020. Major changes include:
a) Product description has been updated;
b) List of permitted optional ingredients has been updated;
c) List of permitted food additives as well as their levels have been updated;
d) Referred test methods have been updated;
e) Chemical and microbiological requirements have been updated; and
f) Labelling clause has been modified.

(Continued from second cover)

In the formulation of this standard, due consideration has been given to the provisions of the Food Safety and
Standards Act, 2006 and the Rules and Regulations framed thereunder; Infant Milk Substitutes, Feeding Bottles
and Infant Foods (Regulation of Production, Supply and Distribution) Act, 1992 and Rules 1993 and the Legal
Metrology (Packaged Commodities) Rules, 2011. However, this standard is subject to the restrictions imposed
under these, wherever applicable.
The composition of the Committee responsible for formulation of the standard is given in Annex E.
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
IS 2 : 2022 ‘Rules for rounding off numerical values ( second revision )’. The number of significant places retained
in the rounded off value should be the same as that of the specified value in this standard.
