A Rapid Silica Gel Method for Measuring Total Free Fatty Acids in Milk

Abstract

Analyses for free fatty acids resulting from lipolytic activity in milk have been, in general, either too time consuming or inaccurate, or both. In the past, considerable attention has been given to methods involving solvent extraction of the fat and free fatty acids followed by titration of the extract. The main disadvantage of these methods is that the water-soluble fatty acids are only partially recovered More recently, chromatographic analyses have been applied to measure the total free fatty acids in saponified milk fat
