Abstract

The present study was carried out to assess the quality and safety of cow, goat and buffalo milk by organoleptic tests, physico-chemical properties, proximate estimation and microbiological studies. The milk samples collected from five different regions of Mathura city. Watery consistency was observed in 50, 18 and 42% of cow, goat and buffalo milk samples respectively, whereas thick, ropy or slimy consistency was observed only in 4, 4 and 20% of cow’s milk only. The COB test was positive in 38, 12 and 20% of cow, goat and buffalo samples respectively. The temperature, pH and specific gravity of all samples were lower than normal prescribed range; however, titrable acidity was higher than normal value in all three species. The moisture content was higher but specific gravity was lower however other proximate parameters showed quite variable values than the normal range. Out of the total, 28 and 20% samples of cow and buffalo milk were positive for formalin adulteration, however, there was no adulteration in goat milk. The microbial load of all milk samples was quite higher than normal prescribed limit in terms of DMC, SPC as well as Coliform and Staphylococcus count.
