Modifications in Richmond formula for calculating Solids-not-fat/Total solids percent in cows’ milk in Gujarat State

Abstract

SNF/TS percent in cows’milk, collected from five dairy plants of Gujarat state were estimated using both volumetric and gravimetric method. Separate modified Richmond formulae for calculating SNF/TS have been proposed for each dairy plant. The equations worked out for individual dairy plant reflects region specificity in composition of milk.The correction factor ranged from 0.57 to 1.24 in one equation and 0.42 to 1.11 in the second to match with the results obtained by gravimetric method.
