Abstract:A method for determination of two artificial synthetic pigments in egg roll (Sunset Yellow and Amaranth) by HPLC was established. the pigments in egg roll After purified was extracted by polyamide, dissolved in water, filtrated and then analyzed by HPLC with a ODS C18 column and the elution of methanol and ammonium acetate (0.02 mol/L). The detection limits, recovery and precision were 0.5 mg/kg, 71.5%~81.4%, and 1.5%~5.9%, respectively.
