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 %.
