Drinks and Carbonated Beverages Sectional Committee, FAD 14

FOREWORD

This Indian Standard ( Second Revision) was adopted by the Bureau of Indian Standards, after thedraft finalized by the Drinks and Carbonated Beverages Sectional Committee had been approved bythe Food and Agriculture Division Council.

In a tropical country like India, the carbonated beverages industry has an important place. Thequality of a carbonated beverage depends on the quality of the various ingredients that go in itsmanufacture - water. acidulants, sweetening agents. emulsifiers and stabilizers, flavour,colour and carbon dioxide being the most important ones. The hygienic conditions of the unitsproducing carbonated beverages also need vigilant control to safeguard public health.

This standard was originally issued in 1963 and then revised in 1973, in which maximum permissiblelimits of thole ingredients which in excess could adversely affect human health were specified.

In this second revision, the scope of this standard has been widened to include beverages for dieteticpurposes, containing electrolyte mixtures, flavoured and sweetened carbonated water with fruit juice,fruit pulp and fruit concentrates, keeping in view the existing trade practices. Several requirementson ingredients have been updated in order to bring the standard in line with existing regulatoryrequirements and manufacturing practices.

In view of the different varieties of carbonated beverages produced in the country, it has not beenpossible to include in the standard the exact or even the range of proportions of different ingredientsrequired for the different varieties of the carbonated beverages.

In the preparation of this standard, due consideration has been given to the provisions of thePrevention of Food Adulteration Act, 1954 and the rules framed thereunder. This standard issubject to the restrictions imposed under these, wherever applicable.

For the purpose of deciding whether a particular requirement of this standard is complied with, thefinal value. observed or calculated, expressing the result of a test or analysis, shall be rounded off inaccordance with IS 2 : 1960 'Rules for rounding off numerical values (revised )'. The number ofsignificant places retained in the rounded off value should be the lame as that of the specified valuein this standard.

METHOD OF MEASURINGGAS VOLUME

c-i APPARATUS

C-l.1 The apparatus consists of 8 pressure gaugebaving a,. bollow spike witb holes in its side. Thebottle' is insetted from the side into the slot providedin tbe neck of the carbon dioxide tester and is securedin place by tightening with a tbreaded system. Thepressure gauge is inserted until tbe needle pointtoucbes the crown cork. There is • sniff valve ontbe gauge stem wbich is kept closed until tbe needlepoint of tbe pressure gauge is forced tbrough thecrown cork. The reading is noted on the gauge.

C-Z PROCEDURE

C-Z.! Clamp tbe bottle in the frame oftbe gas volumetester. Pierce tbe crown cork but do not sbake thebottle. Sniff off the top gas quickly until the gaugereading drops to zero. Make certain to close the valvetbe instant the needle touches zero in the pressuregauge. Shake tbe bottle vigorously until tbe gaugegives a reading tballdditioftll sblking does notchange. Record the pressure. Note the temperatureand record it. Obtain the volume of gas fromTable 2 of IS 2346 : 1973.
