| Abstract: | Preservatives including sorbic acid and benzoic acid in food were quantified by capillary column gas chromatography. The recovery of added standards was 97.4%~103.1% . The Residual Standard Deviation were small: sorbic acid 1.435% and benzoic acid 0.53% . This method is simple ,rapid and accurate. |
