IS : 9532 - 1980 Indian Standard SPECIFICATION FOR CHAKKA AND SHRIKHAND

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 18 June 1980, after the draft finalized by the Dairy Products Sectional Committee had been approved by the Agricultural and Food Products Division Council.

0.2 CHAKKA is an indigenous milk product and it refers to the product obtained after draining off the whey from the curd (DAHI) obtained by the lactic fermentation of milk. It is generally prepared by boiling the milk and preparing curd from it by indigenous method. The curd is hung in a muslin cloth to drain off the whey and it is sometimes pressed during the last stages to hasten the process. Practices using absorbents like sand, ash and strawbeds are also followed for quick drainage of whey. Recently the use of centrifuges to remove the whey is also being practised under a patented process.

0.3 CHAKKA is either made from skimmed milk or whole milk of cow or buffalo. It can also be made from reconstituted skimmed milk, recombined milk or standardized milk. The colour of CHAKKA depends on the type of milk used; it is yellowish from cow’s milk and whitish from buffalo’s milk. 0.3.1 CHAKKA forms an important base for the preparation of milk sweet popularly known as SHRIKHAND in the States of Gujarat, Maharashtra and other adjoining areas. It is also used for the preparation of SHRIKHAND VADI ( indigenous toffee ) intended for preservation and extended use.

0.4 SHRIKHAND is an indigenous sweet, made by mixing CHAKKA with sugar and flavouring agents. It is a slightly sourish-sweet product and is generally consumed with meals or as such.

0.5 This standard is expected to help in exercising the necessary quality control in the manufacture of good quality CHAKKA and SHRIKHAND under hygienic conditions.

IS : 9532-i 1980

0.6 While formulating this standard, due consideration has been given to the data collected by the Western Regional Station of the National Dairy Research Institute, Bombay and experience gained by the National Dairy Development Board, Anand, in collaboration with the Baroda District Cooperative Milk Producers’ Union Limited, Baroda, in developing marketing of SHRIKHAND on commercial scale and the relevant Rules prescribed by the Government of India under the Prevention of Food Adulteration Act, 1954. This standard is subject to the restrictions imposed under the Act, wherever applicable.

0.7 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 : 2-1960”. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
