| Abstract: | Sunset yellow was detected with spectrophotometry,and the λmax was determined.The result showed that the λmax of Sunset yellow was 482 nm,the linear regression equation is y=33.055x+0.0024,r=0.9998,the content of Sunset yellow in the beverage was 0.06418 mg/mL,With good and high accuracy,the relatives standard deviation was 0.15%,and the recovery of standard addition for sunset yellow in beverage ranges from 96.83% to 101.56%.The method was applicable to analysis content of sunset yellow in food industry,especially on beverage. |
