Abstract: 【Objective】 To detect cynuthrin residues in Chinese cabbages from markets of Aksu region, and evaluate the fast kit for cynuthrin.【Methods】 The reference method, industry standard NY / T 761-2008 and the rapid kit for pyrethroid were used to determine cynuthrin residues in Chinese cabbages. The rapid kit was evaluated according to "technical specification for evaluation of rapid detection methods of food".【Results】 None of cynuthrin residues was detected in all samples by the GC method. According to test results in different spiked levels for cynuthrin by the fast test kit, the sensitivity of the kit was 75%, and specificity for pyrethroid pesticide residues was 100%. Compared with the instructions, the false negative rate was 25%, the rate of false positive was 0, and the detection limit concentration was 0.4 mg/kg. 【Conclusion】 Cynuthrin residues in Chinese cabbage sold in Aksu region was lower than the maximum residue limit allowed. The fast kit can be used in rapid screening of cynuthrin residue in Chinese cabbage.

Key words: Chinese cabbage; cynuthrin residue; rapid kit; evaluation

摘要： 【目的】 检测阿克苏市市场中大白菜氟氯氰菊酯农药残留, 进行菊酯快检试剂盒在大白菜氟氯氰菊酯农药残留中适用性评估。【方法】 采用行业标准NY/T 761-2008参比方法和菊酯快检试剂盒对阿克苏市售大白菜中氟氯氰菊酯进行测定,并对菊酯快检试剂盒根据《食品快速检测方法评价技术规范》在大白菜中适用性进行评估。【结果】 所得大白菜样品经气相色谱测定,均未检出氟氯氰菊酯。根据不同加标水平检测结果分析,实验所用快检试剂盒的灵敏度75%,其对菊酯类农残具有特异性100%,其假阴性率25%,假阳性率0,试剂盒检出限为0.4 mg/kg。【结论】 阿克苏市售大白菜氟氯氰菊酯残留均低于 《食品安全国家标准食品中农药最大残留限量》中限量要求,所用试剂盒适用于大白菜中氟氯氰菊酯残留的快速筛查。
