STUDY OF QUALITY TESTING OF MILK POWDER IN STERLING AGRO INDUSTRIES LIMITED – NOVA

Quality assurance of food items is very important parameter of acceptability of as per food safety standards at international level. This study is focused on testing of various milk powders produced at Sterling Agro Industries Limited, Gwalior (India). In this paper, we have presented and analyzed various tests of milk powder for quality control. We performed fat percentage test, moisture percentage test, acidity test, bulk density test, sediment test and maltose test. We observed through standard quality assurance test that in dairy whitener fat was found 6.8% (in ideal case it is upto 20% max.), the moisture contents were found 3.53% (in ideal case it is between 3-4%), acidity test was found 80% successful, bulk density was found 0.625 g/cm3 (in ideal case it is 0.44-0.88 g/cm3), sediment test was found 92% successful (2% A-grade, 90 % B-grade, and 8% rejected) and, maltose test was found 98% successful. Germer centrifuge was used to determine the fat content of the sample, Precisa moisture balance was used to determine moisture content of the sample. Sediment tester was used to determine the sediments in the sample.
