苹果中啶虫脒残留量快检测定及方法评估

为评估苹果中啶虫脒残留快检试剂盒的适应性,本文以阿克苏市市售苹果为检测样品,以《水果、蔬菜中啶虫脒残留的测定液相色谱-串联质谱法》(GB/T 23584—2009)为参比方法,根据《食品快速检测方法评价技术规范》对快检试剂盒进行了评估.结果表明,试剂盒1的灵敏度为100％,特异性为66.67％,假阴性率为0,假阳性率为...

Rapid Determination and Method Evaluation of Acetamiprid Residues in Apples

In order to evaluate the adaptability of the rapid detection kit for acetamiprid residues in apples, the rapid detection kit was evaluated according to the technical specification for the evaluation of rapid detection methods in food,taking apples sold in GB/T 23584—2009 as the reference method. the rapid detection kit was evaluated according to the Technical Specification for Evaluation of Rapid Detection Methods in Food. The results showed that the sensitivity of kit 1 was 100%, the specificity was 66.67%, the false negative rate was 0, the false positive rate was 33.33%, the difference was 8.1,the relative accuracy rate was 80%;the sensitivity of kit 2 was 100%, the specificity was 100%, the false negative rate was 0, the false positive rate was 0, the significant difference was 0, and the relative accuracy was 100%;the sensitivity of kit 3 was 100%, the specificity was 50%, the false negative rate was 0, the false positive rate was 50%, the difference was 8.1, the relative accuracy rate was 80%.
