A study on microbial flora and quality of raw and pasteurized milk from Hyderabad Telangana state, India

Abstract

The present study is to investigate the presence of microbial flora and its quality in raw and pasteurized milk. The milk samples were collected from two different locations in Hyderabad region. A total number of twenty samples were studied including two popular brands of pasteurized milk from dairy out lets. The samples were examined for enumeration of microbial flora on TPC (Total Plate Count) and TCC (Total Coliform Count). The range of TPC and TCC are 1.5x108 to 1.25 x 107 CFU/ml respectively. Purity of pasteurized milk is good in nature. In the present work, preliminary investigations were carried out to ascertain the physicochemical characteristics and nutritional values of various milk samples. Ten raw milk samples and ten pasteurized milk samples from different places of Hyderabad were examined, for a period of six months and analyzed for microbial quality and microbial flora. Pasteurization ensures the quality of milk is up to their required standards.
