According to the national standard GB 5009.35-2023,11 kinds of synthetic colorants in wine were detected by using liquid chromatograph(DAD detector).Through experimental study,it was found that different concentrations of extraction solvent,sample solution,eluent,complex solution and filter membrane type would have a great impact on the recovery rate of colorant.The key control points affecting the accuracy of colorant were found through experiments,and the most suitable reagents and filter membranes were analyzed and screened to ensure the accuracy of results.
