| Abstract: | Selecting undecanoic acid as an internal standard, preservatives including dehydroacetic acid, sorbic acid and benzoic acid in food were quantified by capillary column gas chromatography .The recovery rate of added standards was 96% ～ 104% .The CV between the sample determinations were small: dehydroacetic acid was 0.71%, sorbic acid 0.62 % and benzoic acid 0.82 %. This method is simple, rapid and accurate. |
