摘　　要：本方法将食品样品酸化后,丙酸盐转化为丙酸,用自动进样顶空气相色谱/FID检测,外标法定量。方法准确、简便、快速,可同时连续检测大量样品,能满足快速检测进出口食品中丙酸盐的需要。In this paper, after the sample was acidifyed, propionate was transformed into propanoic acid. The propanoic acid was determinated by Headspace and Auto Injection Gas Chromatography Outstandard quantification. This method was simple and exact. It could continuously determine a great deal of samples at the same time. The method could satisfy the demand on the determination of propanoic acid in import and export food.
