Stepwise Discriminant Analysis of Free Fatty Acid Profiles for Identifying Sources of Lipolytic Enzymes in Rancid Butter

Abstract

Stepwise discriminant analysis techniques, when applied to quantitative data for individual free fatty acids, were useful for characterization of lipolytic enzymes in experimental and commercial rancid butters. Specificities of lipases and esterases for major free fatty acids were determinative for categorization of enzyme types. Lipolytic enzymes in separator slime were heterogeneous. © 1983, American Dairy Science Association. All rights reserved.
