The rates of incorporation into triolein of eight free fatty acids [palmitic acid (16 : 0), linoleic acid (18 : 2), α-linolenic acid (18 : 3), γ-linolenic acid (18 : 3), octadecatetraenoic acid (18 : 4), arachidonic acid (20 : 4), icosapentaenoic acid (20 : 5) and docosahexaenoic acid (22 : 6)] by acidolysis were determined. Lipase TOYO (Chromobacterium viscosum) and Lipozyme (Mucor miehei) both as immobilized lipase were used for the reactions. Lipase TOYO incorporated each free fatty acid into triolein at more than 22%. Lipozyme incorporated each free fatty acid at above 15%, and showed especially high activity toward icosapentaenoic acid. These two lipases were thus concluded applicable to the acidolysis of fat with unsaturated fatty acids.
