摘要
目的:建立测定各类食品中阿斯巴甜含量的系统分析方法。方法:对不同类别的食品采用针对性的前处理手段,选择C18柱和甲醇/水流动相作为分离条件,在208 nm波长处进行检测。结果:方法的最低检出限为2 mg/kg,平均回收率为96.0%～98.9%,相对标准偏差为3.0%～6.1%。结论:方法简单快速,能适用于各类成分复杂的食品的定性定量分析。
Objective：To establish the systemic analysis method for determination of aspartame in foods from different categories. Methods： According to different categories of foods, to study and choose respective suited preparation methods of sample, to adopt the separated conditions of the C18 column and methanol/water, and to detect at wavelength 208 nm. Results ：The detection limit of this method was 2 mg/kg, the average recovery from 96. 0% to 98.9%, and RSD from 3.0% to 6. 1%. Conclusion：This method is simple and quick. It can be widely applied to determination of aspartame in different categories of foods.
