| 摘 要： | 基于酸性条件下,亚硝酸盐与对氨基苯磺酸反应生成有色螯合物,以α-萘胺为显色剂,建立了一种简易快速、易于基层单位使用的有效测定食品中微量亚硝酸盐含量的方法。分别对实验条件的波长、酸度、温度、显色剂用量、显色时间进行优化,取得了最优的实验条件参数,对食品中香肠、腊肉和肉脯样品里的亚硝酸盐含量进行加标回收测定检验,回收率可达98%以上。

| Abstract: | Under acid condition,nitrite and amino acid will produce a mixture—α-naphthylamine.Taking α-naphthylamine as the color development reagent,the author set up a fast and easy method for establishment unit to measure the amount of nitrite in food effectively.The paper had the optimal parametor after comparing the wavelength,acid,temperature,reagent under experimental condition.The recovery is 98% after the determination test of the nitrite in sausage,bacon and preserved fruit. |
