Abstract

Pooled milk samples of Surti buffalo were collected weekly during August 2019 to March 2020 and analyzed for its selected minerals content as well as distribution pattern between soluble and colloidal phases, salt balance, Koestler number and alcohol stability. Fractionation of milk was carried out by rennet coagulation. Contents of Ca, Mg, P and citrate in the milk samples were 175.42, 19.06, 116.84 and 195.77 mg/100 mL, respectively, while those in soluble form were 38.19, 10.24, 39.63 and 164.93 mg/100 mL, respectively. Total and soluble chloride content in the Surti buffalo milk were 113 and 110 mg/100 mL, respectively. The Koestler's number for Surti buffalo milk was less than 3 (2.24±0.19), which corresponds to a milk of normal status. Calcium to phosphorus ratio (Ca:P) and salt balance (Calcium + Magnesium)/ (Citrate + Phosphate) were found to be 1.51±0.16 and 0.62±0.03, respectively. Pooled milk samples of Surti buffalo showed negative results to the alcohol stability test for 66 to 72% v/v alcohol concentration, but not for 75% v/v alcohol concentration.
