��It is generally more reasonable to add it just before or after the pot is started. Generally, the concentration of MSG used is about 0.2-0.5%. my country is currently one of the world’s largest producers and consumers of MSG, and Japan is the world’s largest consumer of MSG. After decades of research and experiments, it has been proven that MSG is one of the important nutrients needed by the human body. It is a natural substance that exists in human food and the human body itself. The human body can completely digest and absorb MSG and carry out normal metabolism after ingestion. Therefore, the 19th Food Additive Regulations Committee Meeting of the Food and Agriculture Organization of the United Nations and the World Health Organization held in the Netherlands in 1987 decided to cancel the restriction on MSG in food. In addition to the above-mentioned medicinal and flavoring uses, sodium glutamate can be used as an organic synthesis intermediate in industry. However, in the world’s annual output of more than 200,000 tons, other uses account for a very small proportion.
4.Sodium glutamate is used as a complexing agent for electroless plating.
