Estimation of content and composition of free fatty acids in pig fat


, : Estimation of content and composition of free fatty acids in pig fat. Rivista Italiana delle Sostanze Grasse 71(1): 25-29

An accurate and precise method of estimating the content and composition of free fatty acids (FFA) in pig fat using a modification of the method of de Jong and Badings for isolating FFA in milk, is described. After isolation of FFA on a glass column filled with alumina and election of neutral lipids, FFA are recovered with acidified diethyl ether. FFA are estimated by gas liquid chromatography after hydrochloric acid-methanol methylization.
