Fatty acid composition of transesterified cod liver oil and plam olein using immobilized Rhizomucar miehei lipase in organic solvents

Abstract

The investigation of the effect of different oil blend ratios and organic solvents on transesterification were studied. Palm olein originally was lacking in linolenic acid, EPA and DHA, was found to contain these fatty acids after transesterification with cod liver oil. Diethyl ether (log P 0.85), hexane (log P 3.5) and isooctane (log P 4.52) were used as different media for transesterification of palm olein: cod liver oil ( 1: 1) blend. The results indicated that diethyl ether and hexane were found as the better organic solvents since they produced a significant increment of DHA composition after transesterification.
