| 摘 要： | 研究了用氯化铵、尿素、氨基磺酸三种试剂处理明胶中的亚硝酸根,并对试剂的用量、反应温度、反应时间、生产成本进行了比较。结果表明,用氨基磺酸处理明胶中的亚硝酸根,用量少,在室温下就能发生反应,而且反应迅速,生产成本低,从而建立了一种处理亚硝酸盐的新方法,并用国标法对处理后的明胶中亚硝酸根的含量进行检测。

| Abstract: | We has studied some methods to process nitrite such as using by ammonium,urea and sulfamic acid.The results have been compared about the quant,the reaction time,the temperature and cost.It showed that sulfamic acid could process the nitrite quickly,simply and high efficiency.It has been used to determine nitrite of edible gelatin by national standard. |
