摘要
国标检测食品中的纽甜前处理较为复杂,简化处理过程,研究不同基质中该试验方法的纽甜含量测定。结果表明,通过乙腈提取,流动相为0.02 mol/L乙酸铵∶乙腈=65∶35,二极管检测器,于波长218 nm处该检验方法回收率为87%~107%,方法检出限为0.2 mg/kg。
GB in the detection of food in the neotame before the treatment is more complex. This experiment simplified the process and studieed the determination of the neotame of the experimental method in different matrices. The results showed that the recoveries were 87%~107% at wave longth 218 nm,the detection limit was 0.2 mg/kg by acetonitrile extraction and mobile phase was 0.02 mol/L ammonium acetate and acetonitrile(65∶35),under the high performance liquid chromatography.
