摘　　要：色素分为合成色素和天然色素。与天然色素相比较,合成色素具有成本低、稳定性好和着色能力强的特点,普遍应用于食品加工中。因此,对合成色素进行研究至关重要。本文参考《食品安全国家标准 食品中合成着色剂的测定》(GB 5009.35—2023),利用高效液相色谱法测定食品中喹啉黄、柠檬黄和日落黄。结果表明,3种物质的分离度高,线性关系良好,加标回收率在95.65%~105.29%,相对标准偏差为0.21%~0.27%。同时,此方法也适用于11种合成色素的测定。Pigment is divided into synthetic pigment and natural pigment.Compared with natural pigments,synthetic pigments have the characteristics of low cost,good stability and strong coloring ability,and are widely used in food processing.Therefore,it is very important to study the synthetic pigment.With reference to GB 5009.35—2023,HPLC was used to determine quinoline yellow,lemon yellow and sunset yellow in food.The results showed that the separation degree of the three substances was high and the linear relationship was good.The recoveries were 95.65%~105.29%and the relative standard deviations were 0.21%~0.27%.The method is also suitable for the determination of 11 kinds of synthetic pigments.
