Abstract:
There is a great concern about quality of the raw milk sold in market. In present investigation, a total of 120 raw milk samples were collected from various farmers and traders marketed milk in all four administrative blocks of the Indore district (M.P.). On physicochemical examination of milk, the mean values for pH and specific gravity were found to be between 6.5±0.03 to 6.6±0.03, 1.024±0.00 to 1.028±0.00, respectively. The colour of the milk in the Indore district was found to be white in 55 (45.83%) samples, while yellowish white in 65 (54.17%) samples. The smell of milk was found to be sweet in 97 (80.83%) samples, whereas unpleasant in 23 (19.17%) samples. None of the milk samples was found to be positive for sediments in the studied area. Present study revealed that the mean values for milk protein in different milk samples was found to be between 3.17±0.09 to 3.38±0.06, respectively and mean values for fat in various milk samples were found to be 3.50% to 4.06%, respectively. Assessment of raw milk samples for common chemical adulterants revealed that 3 (2.50%) for sugar, 26 (21.67%) for detergent, 34 (28.34%) for common salt and 40 (33.33%) for pond water were found to be positive. None of the samples was found to be adulterated with starch, skim milk powder, glucose, ammonium sulphate, formalin, urea, neutralizer, hydrogen peroxide, cellulose, maltose and boric acid. The overall picture of the adulteration of milk in the Indore district showed that out of total, 65 (54.17%) milk samples were found to be positive for at least one adulterant while 55 (45.83%) were found to be negative for common milk adulterant.
