A Study on Triglyceride Composition of Plastic Fats

Triglyceride compositions of beef fat, lard and palm oil were studied by oxidation-fraction-GLC. 1) Saturated and unsaturated fatty acids were randomly distributed in beef fat and lard, but non-randomly in palm oil. Most fatty acids of S3, S2U, SU2 and U3 were randomly distributed in each triglyceride fraction. 2) Lauric acid and myristic acid content was high in S3. Palmitic acid content of beef fat and lard increased, but stearic acid content decreased with unsaturated fatty acyl group as S3
