食品中亚硝酸盐的测定目前多采用盐酸萘乙二胺法,所用显色剂是液体,配制、应用较为繁杂且易失效.我们应用一种固体显色剂,在没有沉淀蛋白和去除脂肪的情况下,对疑为亚硝酸盐中毒的样品进行定性测定,目视观察能快速、准确地得出结果,并可根据反应时颜色的变化及气体产生情况估计出大致含量,及时救治中毒患者.本方法操作简单,重现性好,固体试剂携带应用方便,不易失效. The determination of nitrite in food is based on the method of naphthalene ethylenediamine hydrochloride, the developer is liquid, and the application is complicated and easy to use.We use a solid color reagent without precipitation of protein and fat Under the circumstance, the qualitative determination of the sample suspected of nitrite poisoning can be quickly and accurately obtained by visual observation, and the approximate content can be estimated according to the change of the color of the reaction and the gas production, so as to timely treat and treat the poisoned patients. The method has the advantages of simple operation and good reproducibility, and the solid reagent is easy to carry and easy to carry and is not easy to be invalidated.
