摘要
目的：探讨高效液相色谱同时测定食品中苯甲酸、山梨酸和糖精钠的方法。方法：样品经去蛋白、调节酸碱度、超声提取、过滤等处理，采用HPLC测定。结果：方法的检出限均为1．0mg/kg；相对标准偏差为0.84％～1.20％；平均回收率为92．1％～97．9％。结论：方法准确可靠、简便快速、易于掌握、便于推广。
Objective： To discuss a method of detection for benzoic acid, sorbic acid and saccharin sodium salt in foods by HPLC. Methods：The food samples were deproteinized, adjusted pH, ultrasonic extracted, filtered and analyzed by HPLC. Results： The detection limits were 1.0 mg/kg. The relative standard deviation range of samples added standard substance was 0. 84% - 1.20%. The average recovery rate was 92. 1%- 97.9%. Conclusion：The method is simple, rapid, reliable and accurate. So that, it is suitable for wide - range application.
