  • Trans fatty acid content and acid profiles in margarines and selected fatty foods marketed in Slovenia
    Cencič-Kodba, Zdenka
    A selection of margarines and fatty food products were collected on the Slovenian market and their content of trans fatty acids (TFA) and fatty acid composition were determined by gas chromatogrphy ... (GC). In this study, silver-ion chromatography using Ag-Ion SPE was performed to separate trans and cis isomers, and the isomer fractions were then re-analysed. Almost all fried food and bakery food samples included in this study contained trans fat. The level of TFA varied from less than 0.2% to 6.8%. The highest margarine TFA content was 5.2% and 0.3 was the lowest one. The mean TFA content of margarines was 2.2%. The limit of detection for this method is 0.2%. The main trans fatty acids were trans isomers of monounsaturated octadecenoic acid (C18:1).
