中文摘要:

      近年来, 随着人们生活水平的提高, 食品安全问题日渐成为社会热点话题, 与此同时, 食品安全检测技术也成为了分析工作者关注的重点。其中电位滴定法由于操作简便, 特异性好, 且容易自动化, 而被广泛应用于食品分析领域。本文简单介绍了电位滴定法的原理和装置组成, 重点讨论了其在食品中碘、二氧化硫残留量、过氧化值、酸价、维生素C、脂肪酸值等的测定中的应用, 以期为电位滴定法在食品安全领域中的应用提供一定参考, 并促进自动电位滴定仪在国标方法中的应用。

英文摘要:

      In recent years, with the improvement of people's living standards, food safety issues have become a hot topic in society. At the same time, food safety testing technology has also become the focus of attention of analysts. Among them, potentiometric titration is widely used in the field of food analysis due to its simple operation, good specificity, and easy automation. This article briefly introduced the principle and device composition of potentiometric titration, and focused on its application in the determination of iodine, sulfur dioxide residue, peroxide value, acid value, vitamin C, and fatty acid value in food. It provides a certain reference for the application of potentiometric titration in the field of food safety, and promotes the application of automatic potentiometric titration in the national standard method.
