中文摘要:

      食盐是人们日常生活中必备的调味品, 氯化钠是食用盐的主要成分, 是食盐咸味的主要来源。作为食盐生产企业必须控制的指标, 氯化钠项目的检测尤为重要, 但是不同产品标准规定的氯化钠的检测方法存在着或多或少的差别, 常用的氯化钠测定方法为计算法, 一个项目涉及到5个项目的检测, 且计算过程繁琐。本研究根据食盐中杂质化合物的不同将食用盐分成几个类型, 将复杂的计算过程列表表示, 使计算过程变得清晰明了。同时汇总了现行食用盐标准中氯化钠含量的测定方法并进行了比较分析, 以期给管理部门、生产企业及检验人员提供更多的参考和思考。

英文摘要:

      Salt is an essential condiment in people's daily life. Sodium chloride is the main ingredient of edible salt and the main source of salt flavor. As an index that must be controlled by salt production enterprises, the detection of sodium chloride project is particularly important. However, there are more or less differences in the detection methods of sodium chloride stipulated by different product standards. The commonly used method for the determination of sodium chloride is the calculation method. One project involves the detection of 5 projects, and the calculation process is tedious. In this study, the edible salt was divided into several types according to the impurity compounds in salt, and the complicated calculation process was presented in the list, making the calculation process clear. At the same time, this paper summarized and compared the determination methods of sodium chloride content in the current edible salt standard, in order to provide more references and considerations for the management department, production enterprises and inspectors.
