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
