摘要
目的:建立腌菜、渍菜中诱惑红的反相高效液相色谱测定方法,利用该法与柠檬黄、胭脂红、日落黄等色素同时测定。方法:腌菜、渍菜中诱惑红用聚酰胺粉(200目)纯化,经Eclipse plus C18色谱柱分离,紫外检测器检测,波长254 nm。结果:本方法在1.44-14.4μg/ml范围线性良好,r=0.9999,平均加标回收率为93.3%-93.8%,RSD〈2.1%,诱惑红检出限为0.08μg/ml。结论:本法操作简便、灵敏、准确,适用于腌菜、渍菜中诱惑红、柠檬黄、胭脂红、日落黄等色素的同时检测。
Objective:The content of allura red in salted and pickled vegetables was determined by a reverse phase-high performance liquid chromatography method,which could be used to determine the conent of Tartrazine,Ponceau 4R,and Sunset yellow in salted and pickled vegetables simultaneously.Methods:Allura red in salted and pickled vegetables was purified through polyamide powder(200 mesh),then separated by a Zorbax Eclipse plus C18 column(4.6×250 mm,5 μm).The determination was made by a ultraviolet detector at 254 nm wavelength.Results:A good linear relationship was obtained at the range of 1.44-14.4 μg/ml,r=0.9999.The average recovery ranged from 93.3% to 93.8%,and the RSD was less than 2.1%.The detection limit of allura red was 0.08 μg/ml.Conclusion:The method is simple,highly sensitive and accurate,and could be used to determine the content of Allura red together with Tartrazine,Ponceau 4R,and Sunset yellow in salted and pickled vegetables.
