摘要
Abstract
In this paper,we report a method that allows the simultaneous determination of 6 preservatives including benzoic acid,sorbic acid,dehydroacetic acid and 3 p-hydroxybenzoates in soya sauce.The preservatives in samples were extracted with 20% methanol,separated on a C18 column using a mobile phase made up of methanol and 1.55 g/L ammonium acetate,and detected with a diode array detector.All six preservative compounds were separated successfully and showed a good linear relationship between their concentrations and peak areas.The mean recovery rates across three spike levels were 89%—103% with a RSD ranging from 1.09% to 2.81%.Our results demonstrate that this method is sensitive,selective,simple,convenient and high-recovery and allows the routine determination and food safety control of soya sauce.关键词
