摘要
本文介绍用高效液相色谱法测定食品中草酸的含量,通过与经典滴定法测定草酸含量比较,实验结果表明:高效液相色谱法测定草酸含量结果准确,重现性好。说明本分析方法有关技术指标满足食品中草酸含量分析测试要求,具有操作简单、快速、易掌握、回收率高等特点,为食品中草酸含量测定提供简便快速的实用方法,并对其进行安全性评价,具有实践意义。
The content of oxalic acid in the food was detected by HPLC chromatography. Comparing with the traditional titration method, the results showed that there were accurate and high repeatability. So the method could meet the requirements of relevant indicators of oxalic acid content in food. Bccause of being easy to operate, fast, apt grasping, high recoveries, the method could practical approach for determination of oxalic acid in food, which has practical meaning for appraisal of security.
