食用盐中硫酸根含量品质波动与氯化钠含量品质波动的关系研究

目的探讨食用盐中硫酸根含量品质波动和氯化钠含量品质波动之间的变化关系,从多方面考察食用盐的均匀性。方法选取市场上比较普遍的、具有代表性的不同种类食用盐产品,采用国家标准检验方法,对批量盐产品的硫酸根含量和氯化钠含量进行检测,通过统计方法计算出硫酸根含量的品质波动和氯化钠含量的品质波动。结果发现硫酸根含量的品质波动和氯化钠含量的品质波动这2个参数在表示不同盐产品的均匀性时呈现一致性。结论硫酸根含量的品质波动也可以作为考察盐产品的均匀性的指标,这对抽样检验的代表性和生产过程中品质波动的考察有指导意义。

Relationship between quality fluctuation of sulfate content and quality fluctuation of sodium chloride content

Objective To investigate the relationship between quality fluctuation of sulfate content and quality fluctuation of sodium chloride content for investigating the uniformity of edible salt products. Methods Different raw materials and familiar edible salt products were selected as the research objects. The sulfate content and sodium chloride content were tested by national standard analytical method. Quality fluctuation of sulfate content and sodium chloride content were expressed as the standard deviation by calculating the data of sulfate content and sodium chloride content. Results The quality fluctuation of sulfate content and the quality fluctuation of sodium chloride content showed consistency in the uniformity of different salt products. Conclusions The quality fluctuation of the sulfate content can also be used as an index to evaluate the uniformity of the edible salt products.
