高效液相色谱法同时测定食品中5种添加剂

目的：建立反相高效液相色谱法同时测定食品中5种添加剂的检测技术。方法：利用反相高效色谱法同时检测谈料、酱菜以及发酵性豆制品中5种添加剂含量。结果：本方法测定食品中5种添加剂，溶液浓度范围在0.5～50mg／L线性关系良好，相关系数均达0．999；乙酰磺胺酸钾、苯甲酸、脱氢乙酸、山梨酸、糖精钠最小检出浓度分别为0.062，O．074，0．066，0．037，0．105mg／L；标准偏差均小于5．0％；饮料、酱菜和发酵性豆制品中添加剂的回收率为96.8％～101．6％。结论：方法快速简便，用于实际样品检测，结果令人满意。

Simulaneous dertermination of five kinds of additives in food by RP-HPLC

Objective:To set up a method for simulaneous determination of five additives in food.Methods:The high-effect chromatography making use of opposition checks drink pickle at the same time and the bean product fermenting was used for determining by 5 kinds of additives contents.Results:Solution concentration range depended on 0.5~50 mg/L lineaity,relation fine,the relevance modulus amounted to 0.999 without exception.The soursulfan acet ophenetidin ilamide potassium,benzoic acid,dehydro aectic acid,sorbic acid,saccharin sodium minium inspects up out tickness being 0.062,0.074,0.066,0.370,0.105 mg/L.The standard deviation was smaller than 5.0%.The additive hit back rate was 96.8% in drink pickle and the nature bean product fermenting 101.6%.Conclusion:This method is simple and rapid to achieve satisfactory results.
