Abstract:
Milk quality control tests are designed to ensure that milk products meet accepted standards for chemical composition and purity as well as levels of different micro-organisms. To assess the quality of the different milk brands available in Tirupati, Andhra Pradesh. Using questionnaire, information was elicited among the local people, to know the highly preferred milk sample; 9 more samples of varied brands were selected for the present study. Microbial, organoleptic and physiochemical parameters tests were carried out in all the 10 samples. Majority of the consumers preferred M7 (40%) milk sample. The microbial quality assessment reveals that 50% samples recognized as good and the remaining is fair quality. The organoleptic assessment of samples indicate that the M3, M7 and M10 milk were in the category of good and the remaining samples were satisfactory. The colour and pH observed was in the normal condition. There was a slight variation observed the acidity and SNF levels of the collected milk samples. A majority of the milk samples have the normal COB and CLF reading except some milk samples. This indicates that the adulteration of milk with water is the reasons.
