Abstract: A method for simultaneously determining sorbic acid, benzoic acid and saccharin sodium in processed fishery product was established. A satisfying pretreatment method was developed by using ferrocyanic cyano-potassium and acetic acid zinc as precipitating agents. The overall detection limits of the three compounds are 0.5 mg/kg, and the average recovery is in the range of 92.7%~106.5%.

Key words: processed fishery product, sorbic acid, benzoic acid, saccharin sodium, high performance liquid chromatography
