Quality Assurance of Marketed Raw Milk in Bhopal city, MP, India

摘要

The study was conducted to evaluate physicochemical and bacteriological quality of raw milk in Bhopal city (M.P) India. Milk samples were collected randomly encompassing whole city from milk vendors and milk vending shops for two consecutive years i.e. 2009-2010. The physicochemical parameters include Temperature, pH, Titrable acidity, Density and Conductivity, Additionally microbiological evaluation were based on Standard plate Count and Coliform counts. The results for milk vendors showed Temperature 18.19C, pH 6.61, Titrable acidity 0.183%, density 1.024g/ml, Conductivity 3.39 ms/cm and SPC 6.13-0.083 Ccfu/ml and Coliform count 4.01-0.1413 cfu/ml. furthermore the values of sample for milk vending shops were Temperature 13.6C, pH 6.34, Titrable acidity 0.181% , Density 1.026 g/ml, Conductivity 3.64 ms/cm, and SPC 6.37-0.085 Ccfu/ml and Coliform count 4.01-0.180cfu/ml. statistical analysis of data revealed that there is significant difference between sample of different sources at 5% significance level.
