摘  要:
反式脂肪酸是一类不饱和脂肪酸,来源较为广泛,并对人体健康存在着危害。目前欧洲各国已对其在食品中的含量有一定限制。本文应用气相色谱法对几种市售油脂产品中的反式脂肪酸含量(以反油酸C18:1△9为例)的含量进行了测定分析,并讨论了气相色谱分析中固定相的选择,为反式脂肪酸检测中固定相的选择提供了更多参考。试验结果表明:检出人造黄油中反式油酸含量为9.9%~14.5%,鲜奶油中含量为12.5%。

摘  要:
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.
