Abstract
A model triglyceride mixture was prepared by the random interesterification of hardened coconut oil. The mixture was analyzed by GC-MS, The fatty acid composition of each triglyceride group having the same total acyl carbon number was determined by the relative intensity distribution of the specific fragment ion containing one of three acyl groups of a triglyceride molecule. Correction of fatty acid composition was made using the correction factor from the GC-MS data of the standard diacid triglyceride.
The fatty acid composition determined as by GC-MS agreed well with that by theoretical calculation according to random distibution of acyl groups and also agreed with that by conventional hydrolysis-GC.
