中文摘要:

      目的 建立一种基于化学比色原理的方法评价食品安全快速检测产品的质量。方法 采用一般指标和技术指标相结合评价亚硝酸盐快检试剂产品, 确定质量评价的具体指标。结果 10家公司产品的一般指标均不能满足要求, 有待改善; 1家公司产品的原理不同于KJ201704《食品中亚硝酸盐的快速检测盐酸萘乙二胺法》; 4家公司产品的色阶卡与实际颜色不符; 1家公司产品的检出限、与参比方法比较及假阴性率不符合要求。结论 该方法较为全面地反映快速检测产品质量的优劣, 为合理验证和评价食品快速检测产品质量提供依据。

英文摘要:

      Objective To establish a method for evaluating the quality of food safety rapid inspection products based on the principle of chemical colorimetry. Methods The nitrite rapid test reagent product was evaluated by combining the general indicators and the technical indicators to determine the specific index of the quality evaluation. Results The general indicators of the 10 companies' products could not meet the requirements and needed to be improved, the principle of 1 company's products was different from KJ201704 Rapid determination of nitrite in food by naphthalene ethylenediamine hydrochloride method, the color scale cards of the products of 4 companies did not match the actual colors, and the detection limit, the comparison with the reference method and the false negative rate of 1 company's products did not meet the requirements. Conculusion The method comprehensively reflects the quality of the rapid detection product quality, and provides a basis for rationally verifying and evaluating the quality of the food rapid detection product.
