MSG is a type of seasoning, the main component of which is sodium glutamate. It refers to sodium glutamate crystals that are fermented and purified from grain.
Production process:
Use sugar or starch raw materials to produce glutamic acid. Then glutamic acid is extracted through isoelectric point crystallization precipitation, ion exchange or zinc salt refining, and then through decolorization, deironization, evaporation, crystallization and other processes to produce sodium glutamate crystals, commonly known as monosodium glutamate, its main component is Glutamic acid and table salt.
When MSG is heated at 100°C for half an hour, only 0.3% of sodium glutamate will produce sodium pyroglutamate, which has little effect on the human body.
MSG was discovered and patented by the Japanese Ajinomoto Company in 1909. Pure MSG appears as a white crystalline powder.
MSG has no direct nutritional value to the human body, but it can increase the flavor of food, arouse people's appetite, and help improve the human body's digestibility of food. ?The main component of MSG, sodium glutamate, also has the effect of treating chronic hepatitis, hepatic coma, neurasthenia, epilepsy, achlorhydria and other diseases.
