Comparison of detection method of fatty acid in edible oils

Hong Zhang

Abstract

Fatty acids in oils were detected by GC-MS.Three methylation methods were compared.The separation effects of DB-5ms and VF-23ms capillary column on 37 mixed fatty acid methyl esters were compared.The results showed that the VF-23ms column had a better separation effect.4% hydrochloric acid methanol method has the best effect of methyl esterification.The research provided a reference for detection of fatty acids in oils by GC-MS.
