公司介绍
A method for the determination of quinoline yellow in wine, candy and chocolate by SPE - HPLC was developed. The samples were extracted by water and 70% methanol aqueous solution, and the extracted solution was purified by polyamide solid phase extraction column. The C18 column was used for gradient elution with 0.02 mol/L ammonium acetate solution and methanol as mobile phase. The content of quinoline yellow in wine, candy and chocolate was determined by HPLC. In the range of 5.0 ~ 100.0mg/L, the linear correlation coefficient was greater than 0.999 9. The detection limit of this method was 2.5 mg/L for wine, 2.5 mg/kg for candy and 2.5 mg/kg for chocolate. The average recoveries of the samples were 83.2% ~ 92.2%, and the relative standard deviations of the determination results were all less than 4.4%(n=6).
