Determination of Sodium Glutamate in Chicken Powder by Amino Acid Autoanalyzer

本文利用氨基酸自动分析仪测定鸡粉调味料中谷氨酸钠的含量,测得鸡粉调味料谷氨酸钠含量达0.27-0.32 g/g。该方法自动化程度高,重现性和准确度都较好,样品前处理简便易操作,经处理后直接上机分析,排出了其他物质的干扰,能够快速、准确地测出鸡粉中谷氨酸钠的含量。通过不同样品和相同样品两种加标方式,测得回收率可达到99.41-103.66%,方法精密度为0.39%。

This paper determined the content of sodium glutamate in chicken powder by amino acid autoanalyzer.The monosodium glutamate content in chicken powder was up to 0.27-0.32 g/g.This method had high degree of automation,reproducibility and accuracy.It was also easily operated with good reproducibility.Sample preparation was simple and direct.Its recovery can achieve 99.41-103.66% and the precision was 0.39 %.
