Modification of goat milk fat triglycerides by immobilized lipase
No full textThe lipid fraction of goat milk was subjected to transesterification using
a commercially available immobilized lipase to decrease the amount of
short- and medium-chain fatty acids (C4–C14) by enrichment of the
reaction mixture with long-chain (C18:1 and C18:2) fatty acids. Aliquots
were taken during transesterification at different reaction times and analyzed
for triglycerides and their fatty acid components. The gas chromatographic
analyses of triglycerides (previously isolated by thin-layer
chromatography) showed that at 6 h reaction under the experimental
conditions led to the greatest reduction of the low molecular weight
triglycerides (C22–C38) and concomitantly to the greatest increase in the
higher molecular weight triglycerides (C48–C54). These changes correlated
with the variations observed in the fatty acids of the triglyceride
fraction
