摘  要:
建立了毛细管柱气相色谱法同时测定酱腌菜中山梨酸、脱氢乙酸、苯甲酸的方法。样品经盐酸酸化后,乙醚提取,经HP-FFAP(30.00 m×0.32 mm×0.25μm)毛细管柱分离后,采用火焰离子化检测器(FID)检测酱腌菜样品中山梨酸、脱氢乙酸、苯甲酸的含量。结果表明,山梨酸、脱氢乙酸、苯甲酸含量分别在5.0~400 mg/L线性良好(r>0.999),平均回收率为87.6%~97.7%,RSD(n=5)在0.8%~3.7%。该方法快速、准确,适用于同时测定酱腌菜样品中山梨酸、脱氢乙酸、苯甲酸的含量。

摘  要:
A method based on capillary gas chromatography was developed to detect sorbic acid, dehydroacetic acid and benzoic acid in pickled vegetables. After being acidified, samples were extracted with ether, separated on a capillary column(HP-FFAP, 30.00 m×0.32 mm×0.25 μm)and detected with a flame ionization detector(FID). The result showed that the linear range was 5.0-400.0 mg/L and the linear correlation coefficients of sorbic acid, dehydroacetic acid and benzoic acid were greater than 0.999. The recoveries ranged from 87.6% to 97.7% with RSD(n=5) of 0.8%-3.7%. This method was stable, rapid and repeatable to detect the sorbic acid,dehydroacetic acid and benzoic acid in pickled vegetables.
