| Abstract: | Objective To investigate the content of trans fatty acid in food by using gas chromatography. Methods The contents of trans fairy acid in several kinds of fat products were determinated and analysed by using gas chromatography. Results The trans - and cis - fatty acids were separated with each other, and the result showed that the contents of trans fatty acid were 9.9% - 14.3% in butter and 12.8% in cream. Conclusion Gas chromatography has the advantages of simplicity, repeatability and sensitivity, and it can be used for detecting trans fatty acids in food in many laboratories. |
