摘要
苏丹红I-D_5作为食品中非法添加物分析用内标试剂,为食品中非法添加物的分析检验提供了可靠依据,对于规范苏丹红I的使用,避免其在食品、调味品和化妆品中的非法添加有着重要作用。根据苏丹红I的化学纯度分析检测标准GB/T 19681-2005《高效液相色谱法通则:食品中苏丹红染料的检测方法高效液相色谱法》操作规程,利用高效液相色谱仪,采用外标法,建立标准曲线,优化了苏丹红I-D_5的化学纯度分析方法。并对整个测试过程中各不确定度进行了评估,确定了不确定度的主要来源,最终得到合成不确定度为3%,扩展不确定度为6%。
As internal standard reagent for illegal additives in food analysis,Sudan I-D_5 provides a reliable basis for the analysis of the illegal additives in food inspection. It plays an important role for the standardization of the usage of Sudan I,as well as avoiding the illegal add in food,spices and cosmetics. According to the operating process of standard GB / T 19681-2005 Chemical purity of Sudan I-D_5. The method for the determination of Sudan dyes in foods High performance liquid chromatography. High performance liquid chromatography（ HPLC） has been established for detecting the chemical purity of Sudan I-D_5. Contents has been quantified with external standard method and the the standard curve has been established.Uncertainty component was evaluated and composed,main source of uncertainties were obtained. Synthetic uncertainty was 3%,the expanded uncertainty was 6%.
