摘要:A new detergent method using Babcock's test bottle for estimating fat content in milk products was investigated. The volume each component in the detergent reagent, consisting of Tween 80, sodium salicylate, and amyl alcohol, to be added to milk and ice cream was determined, the fat content obtained being compared with those obtained by the detergent method already reported and Rose-Gottlieb's method. The fat content in milk products estimated by this method was the same as that obtained by the Rose-Gottlieb's method.
