高氯酸滴定法测定掺杂味精中谷氨酸钠的含量

Determination of MSG in adulterated Weijing with perchloric acid titration method

高氯酸滴定法替代旋光法,能够有效地排除蔗糖、淀粉等这些具有旋光性或水不溶性物质的干扰,准确、方便地测出掺杂味精中谷氨酸钠的含量。

Instead of rotatary method,in this paper perchloric acid titration was chosen to determine MSG content in adulterated Weijing.The method was accurate and convenient,and able to exclude disturbance from rotatary and insoluble matters such as sugar and starch.
