OBJECTIVES: Industrially produced trans fatty acid (iTFA) have adverse health effects and thus their consumption should be limited. The aim of this study was to determine and compare the iTFA content in frequently consumed food products by young adults from the Serbian and Slovenian market with supposedly elevated iTFA content in 2015. At the time of this study, there was no recommended limit of iTFA in both countries, and reduction of iTFA in foods was on voluntary basis. METHODS: We determined iTFA content in food products, 19 from the Serbian and 22 from the Slovenian market, blinded and analysed in the same analytical run. Contents of fatty acids (FA) methyl esters were analysed by capillary gas chromatography with a flame ionisation detector. Heptadecanoic acid was used as internal standard. Individual FA along with TFA were expressed as percentages of total measured FA. The amount of each FA in the sample was then calculated from the response factor and the transformation factor of the FA from the FA methyl ester content. RESULTS: Elaidic acid (C18:1t) was found as the most abundant TFA in analysed products, ranging from 0.52 g/100 g of total FA in chocolate candy up to 60.4 g/100 g in a salami from Serbian market. In Slovenian products, the values for elaidic acid were lower, 0.04-3.95 g/100 g of total FA, except in one type of wafers (24.3 g/100 g). CONCLUSIONS: The majority of analysed products from the Serbian and three from Slovenian market exceeded the recommended WHO and EU limit of 2% iTFA of total fat in foods. Samples of frequently consumed salami, wafers, tea biscuits, and snacks were identified as products with potentially higher burden of iTFA in diets of young adults in Serbia.

AIM: The purpose of our study was to determine the content of trans fatty acids in early human breast milk as an indicator of dietary exposure in a sample of Roma breast-feeding women and in a sample of women from the general Czech population. METHODS: We collected samples of early human milk from 43 Prague women from the general population and 21 Roma women. After lipid extraction, the fatty acids were converted into methyl esters (FAMEs). Finally, gas chromatography with flame ionization detector (GC-FID) analysis on a CP-Sil 88 column was used to determine C18:1 trans monoenic fatty acid levels and total trans isomers fatty acid levels in human milk. RESULTS: A significantly higher content of C18:1 trans fatty acid isomers was detected in human milk fat from Roma mothers than in women of the general population (2.73 vs. 2.09%, p < 0.05). Both groups monitored did not differ in the representation of total fatty acid trans isomers. Differences in the frequency of consumption of certain TFA sources (butter, fried crisps) were established. CONCLUSIONS: The study proved a higher fatty acid trans isomers content in Roma breast-feeding mothers in the Czech Republic, and this is probably related to their bad eating habits. (c) 2007 S.
