Abstract
The high resolution gas chromatography of fatty acid methyl esters obtained from seven samples of domestic soft type margarines for home use was carried out using glass capillary columns. The content of the cis and trans isomers of linoleic and linolenic acids was determined. The content of the geometrical and positional isomers of oleic acid was obtained by gas-liquid chromatography of the ozonolysis products of the cis and trans monoenoate fractions separated with silver nitrate-impregnated silicic acid thin-layer chromatography. The specific features of the fatty acid composition of the margarines are discussed.
