摘要
目的：应用高效液相色谱-质谱联用技术测定蛋类食品及蛋制品中的苏丹红四号。方法：用固相萃取法对样品提取液进行净化处理，利用液相色谱-质谱联用仪分析苏丹红四号。结果：该方法相对标准偏差在1．21％-2．56％之间，回收率在88．0％-96．3％之间，线性相关系数r〉0．9993。结论：本方法准确可靠，可应用于蛋类食品及蛋制品中苏丹红四号的测定。
Objective： To determine sudan Ⅳ in egg products by high performance liquid chromatography mass spectrometry. Methods： A method for determination of sudaniv in egg products by reverse phase high performance liquid chromatography was developed. Solid - phase extaction was used to purify the subject of the experiment. Results： The relative standard deviations were 1.21% -2. 56% and the recoveries were 88.0% - 96. 3%. The correlation coefficients for the linear equation was 0. 9993 - 1. 0000. Conclusion. The method is accurate. It had been applied to the determination of sudan IV in egg products.
