味精是一种广泛使用的鲜味剂,主要成份是麸酸钠。测定麸酸钠的主要方法是旋光计法,具有快速、准确的优点,但此方法离不开旋光仪。在实验室缺乏旋光仪的条件下,也可以用酸度计法来测定。我们在多次实验对照中摸索此方法一些关键步骤,从而获得准确的实验结果。现具体介绍如下:1
MSG is a widely used flavor agent, the main ingredient is sodium glutamate. The main method for the determination of sodium glutamate is the polarimeter, which has the advantages of rapid and accurate, but this method can not be separated from the polarimeter. In the absence of a polarimeter in the laboratory, acidometry can also be used to determine. We have explored some of the key steps of this method in numerous experimental controls to get accurate experimental results. Specific introduction is as follows: 1
