Title: Determination of Sorbic Acid and Benzoic Acid in Foods Using Multi-sample Simultaneous Extraction-gas Chromatography
Abstract: A novel method for determination of sorbic acid and benzoic acid in food was developed using multi-sample simultaneous extraction-gas chromatography.The samples and standard series solution were extracted simultaneously,with a mixture of ethyl acetate and hexane(1+1) as extraction solvent.The contents of sorbic acid and benzoic acid were measured by SE-30 wide caliber capillary.In the selected conditions,the detection limit for sorbic acid and benzoic acid was 1 mg/kg,the linear range was 25-500 mg/kg,the recoveries was 93.2-102.4% and the RSD was 1.9-4.1%.The method was simple,rapid,easy control and low-cost.It can be used for the rapid quantitative analysis of batch sample.
