Abstract： High performance liquid chromatography was used to determine the fast green FCF of artificial synthetic pigments in food. Four different pretreatment conditions were compared， including direct extraction method， liquid-liquid extraction method， polyamide powder adsorption method and solid phase extraction method. Prepare different matrices such as wine， candy， and candied fruit for determination， analyze the accuracy and precision of the measurement results， and combine the convenience and economic benefits of the method to determine the optimal pretreatment method for various matrices.

Keywords： fast green FCF; high performance liquid chromatography; pretreatment; food
