Abstract: It is well accepted fact that milk is the most precious liquid food in the nature. The importance of this ‘almost an ideal food’ in human diet doesn’t need any emphasis. In India, more than 80 percent of the milk produced is marketed by unorganized sectors and less than 20 percent by the organized sector. Many of producers did not follow appropriate milking and subsequent handling practices which detoriates the quality of milk. These makes necessary to check the quality of milk sold loose. The quality of milk can be tested by assessing its microbial quality and physico-chemicals parameters, along with sensory attributes.
The area selected for study was Dapoli and villages around Dapoli, viz. from Mauje Dapoli, Jalgaon, Gavhe, Gimhavne and Kherdi. The research was carried out in three distinct season’s viz. summer from April to June, Monsoon from July to August and winter from November to December. Six samples were collected from each vendor in each season that is 30 samples were collected in each season. The samples were analyzed for physico-chemical, microbial and sensory attributes with respect to the seasonal impact on it.
In present study, it was observed that in winter season showed highest percent fat and percent total solid, while in rainy percent acidity, percent ash and E. coli count was higher. The summer season showed highest DMC and SPC count. Dapoli showed highest E. coli count i.e. 46.93 cfu/ml. Highest DMC and SPC was observed in Jalgaon i.e. 93.72 x 105 cfu/ml and 28.57 x 105 cfu/ml, respectively. Highest specific gravity and percent acidity was observed in Gavhe i.e. 1.0276 and 0.16 percent. Samples from Gimhnave showed highest fat, total solids and ash i.e. 5.75 percent, 13.96 percent and 0.58 percent, respectively. In organoleptic test, the result was based on sensory evaluation and scoring system. Highest mean scores for flavour, consistency and general appearance was given to samples from Gimhavne i.e. 8.11, 8.25 and 8.31, respectively.
