Abstract/OtherAbstract:
|
The content of <italic>trans</italic> fat in foods is most commonly determined by summing the levels of individual <italic>trans</italic> fatty acids (FA), analyzed as FA methyl esters (FAME) by gas chromatography. Current Official Methods of the American Oil Chemists' Society (AOCS) enable quantitation of total <italic>trans</italic> fat in foods but were not designed for the determination of <italic>trans</italic> FA isomeric compositions. In the present study, the content of <italic>trans</italic> fat in 32 representative fast food samples ranged from 0.1 - 3.1 grams per serving, as determined according to AOCS Official Method Ce 1j 07. Further analysis of FAME using the 200 m SLB IL111 ionic liquid column yielded quantitative results of total, <italic>trans</italic>, saturated and <italic>cis</italic> unsaturated fat that were comparable to those of Method Ce 1j 07, and also allowed for the complementary determination of individual <italic>trans</italic> 18:1, <italic>trans</italic> 18:2 and <italic>trans</italic> 18:3 FA isomeric compositions under conditions suitable for routine sample analysis. |
