摘要: 建立高效液相色谱法检测食品中亮蓝的新方法,初步证实食品中亮蓝主要为3种异构体的混合物。用聚酰胺层析柱净化,高效液相色谱法分离。色谱柱为Inertsil ODS-SP C18 (150mm×4.6mm,5μm),流动相为甲醇-0.02mol/L乙酸铵溶液,检测波长629nm。加标回收率为91.1%~94.7%。

Abstract: A new analytical method was developed for the determination of brilliant blue in food by high performance liquid chromatography (HPLC). It was preliminarily confirmed that the presence of brilliant blue in food was mixtures of its three isomers. Sample extracts were purified by polyamide column chromatography and separated on an Inertsil ODS-SP C18 (150 mm × 4.6 mm, 5 μm) column using a mobile phase made up of methanol and 0.02 mol/L ammonium acetate solution. The detection wavelength was set as 629 nm. The spike recovery rates across three spike levels were in the range of 91.1%-94.7%. The method was simple and accurate.

Key words: brilliant blue isomers, high performance liquid chromatography (HPLC), food
