Abstract:

The presence of conjugated trienoic acids were found in the purified fish oil from the Japanese sardine by an analysis of high performance liquid chromatography equipped with a photodiode-array detector. Gas chromatography-mass spectrometry indicated that main conjugated trienoic acids were those of 16:3, 20:5, and 22:6. Conjugated trienoic acid of 16:3 was identified as a cyclopropanoid acid with conjugated triene by NMR analysis. All conjugated trienoic acids were formed by heat treatment during the deodorization of fish oil, but not found after de-gumming, alkaline refining, and bleaching. Conjugated trienoic acids of 16:3, 20:5, and 22:6 originated from 16:4n-1, 20:5n-3 (EPA), and 22:6n-3 (DHA) in the fish oil during the heat treatment for deodorization.
