| Abstract: | The contents of trans fatty acids （ TFA） in twenty samples of chocolate were determined by gas chromatography internal standard method in the present study .The esults showed that the samples with cocoa butter replace as the main raw material TFA content was ND ~4.96%,while the samples with cocoa butter as the main raw material ,the TFA content was ND~0 .844%.The trans C18：1 was the most in TFA in chocolate we tested . |
