The mean content of CLA in fat isolated from the yoghurts examined ranged from 0.41% to 0.43% of the total fatty acid composition, whereas in fat extracted from the bioyoghurts under study it ranged from 0.41% to 0.44%. Investigations demonstrated that in commercial yoghurts and bioyoghurts analysed the content of cis9trans11 C18:2 acid (CLA) and the total content of trans isomers of C18:1 acid were alike. Determinations were carried out with the method of gas chromatography using a 100-m capillary column with CP Sil 88 phase. The research was aimed at comparing contents of cis9trans11 C18:2 acid (CLA) and trans isomers of C18:1 acid in commercial yoghurts and bioyoghurts as well as acquiring information whether CLA concentration in yoghurts and bioyoghurts differs from that in the initial material.
