Research and application of a rapid detection kit for the determination of anion synthetic detergent residue on the surface of tableware

目的研制用于餐饮具中阴离子合成洗涤剂快速检测的试剂盒。方法餐具经过冲洗后,采用三氯甲烷萃取,有机相通过与标准色阶卡目视比色快速判读待测餐饮具中阴离子合成洗涤剂的残留。结果所研发的快检试剂盒检验结果与实验室方法一致,灵敏度为100%、特异性为100%、假阴性率为0%和假阳性率为0%。符合食品快速检测方法评价技术规范要求。试剂盒在室温条件下,储存3个月性能稳定。结论研制的快检试剂盒可用于餐饮具中阴离子合成洗涤的快速检测,适合于现场快检。

Objective To develop a rapid detection kit for the determination of anion synthetic detergent residue on the surface of dinner and drinking set. Methods The surface of the dishes was washed by the distilled water, and then the sample liquid was extracted by trichloromethane. The anion synthetic detergent residue value was tested by visual colorimetry card. Results The test results of the kit were consistent with the results of available national standard method. The sensitivity of the rapid detection kit was 100%, the specificity of the kit was 100%. The false negative rate was 0% and the false positive rate was 0%. The kit could meet the technical specifications of the performance specification requirements. The kit maintained stable within 3 months when stored at room temperature. Conclusion The quick detection kit can be used for the quick detection of anion synthesis washing in tableware, and is suitable for the quick detection on site.
