摘  要:
我国对各种食品中氯化钠含量有严格的要求,国标方法测定酱卤肉、熟鱼制品及其他一些产品中氯化钠含量较难判断滴定终点。该文采用灰化法对样品进行处理,之后采用间接滴定法测定氯化钠含量。结果表明:此方法回收率最高可达95%,精密度2.05%,与标准方法测定结果之差每100 g不超过0.2 g,符合国标对误差的要求。

摘  要:
Our country has strict requirements for the contents of sodium chloride in various foods,the end point of titration of sodium chloride content is difficult to judge the sauce braised pork,cooked fish products and other products in the determination of the national standard method.The ashing method was used to deal with the samples,and using indirect titration method for the determination of sodium chloride content.The results showed that this method recovery rate up to 95%,a precision of 2.05%,and the standard method for the determination of the difference of each 100 g was less than 0.2 g,which met the national standard requirements for error.
