| Abstract: | This paper established a high performance liquid chromatography method for simultaneous detection of seven synthetic colorants in milk-containing beverages.Gradient elution was performed with ammonium acetate-(methanol+acetonitrile)as mobile phase,and solid phase extraction column was used for sample pretreatment.The recovery rate of 7 pigments in milk-containing beverage was 91.4%~107.5%,and the repeatability was all<5%.The method has simple pretreatment,good accuracy and repeatability,and can be used for simultaneous detection of 7 pigments. |
