General description
诱惑红（E29）时一种单偶氮染料，作为合成着色剂添加到各种饮料、果汁、烘培食品、肉类和糖果产品中。根据指令 94/36/EC 的附件 I，它已被欧盟(EU)注册批准用作食品添加剂。美国食品和药物管理局(FDA)已批准其在食品、药物和化妆品中的使用，作为苋菜红（红 2）和赤藓红（红 3）的替代品。它通常被称为食品红40号和食品、药品和化妆品红40号（FD&C红40号）。
Application
此分析标准品可被用于以下实验：
- 通过UV-Vis分光光度法对诱惑红和酒石黄进行定量分析,这两种染料是从食品样品中通过基于疏水性共晶溶剂（HDES）的液相微萃取(LPME）法提取的
- 使用基于玻璃碳电极(GCE)的伏安电化学传感器对软饮料粉末样品中的诱惑红进行纳摩尔水平的测定，该玻璃碳电极用掺有碳黑颗粒和离子液体1-丁基-3-甲基咪唑四氟硼酸盐的交联壳聚糖膜改性
- 通过反相高效液相色谱(RP-HPLC)联用UV检测器同时分析小熊软糖、口香糖和糖果样品中的日落黄 FCF、诱惑红 Ac、喹啉黄 WS和酒石黄
- 构建基于钴络合物修饰的碳糊电极(CoC/CPE)的电化学传感器，用于循环伏安法测定明胶和药物剂量的对乙酰氨基酚中酒石黄、日落黄和诱惑红的含量
- 通过液相色谱-串联质谱法对18种辣椒粉和六种蜜饯中20种合成染料进行多残留分析
Packaging
