通常采用旋光法和中和法〔１〕来测定味精中麸氨酸钠的含量。经过实验探索，我们应用原子吸收分光光度法可间接地测定味精中麸氨酸钠含量，操作简便，重现性好，能检出０．１０ｍｇ麸氨酸钠，取得满意效果。现报告如下。原理氨基酸在碱性条件下能定量地从磷酸铜沉淀中络合... Usually using optical rotation and neutralization method [1] to determine the content of sodium glutamate in MSG. After experimental exploration, we can determine the content of sodium glutamate in MSG indirectly by atomic absorption spectrophotometry. It is simple, reproducible and can detect 0.10mg sodium glutamate with satisfactory results. The report is as follows. Principle Amino acids can be complexly complexed from copper phosphate precipitates under alkaline conditions ...
