Abstract: The trans fatty acid is a kind of unsaturated fatty acid,there are very extensive source,and it is extremely harm for health. The content of trans fatty acid in food have already been restricted in some European countries recently. The content of trans fatty acid (take trans -oleic acid C18:1△9 as example) in several kind of fat products has been determinated and analysed using gas chromatography and the choice of the stationary phases in gas chromatography has been discussed. More choices of stationary phases in determining the trans fatty acid was offered. The result shows that the content of trans fatty acid is 9.9%~ 14.5% in butter and 12.5% in cream.

Key words: trans fatty acid, gas chromatography, stationary phases
