Production process:
Glutamate is produced from sugar or starch. Then glutamic acid is extracted by isoelectric point crystallization precipitation, ion exchange or zinc salt refining, and then sodium glutamate crystal, commonly known as monosodium glutamate, is made by decoloration, iron removal, evaporation and crystallization, and its main components are glutamic acid and salt.
When monosodium glutamate is heated at 100℃ for half an hour, only 0.3% of sodium glutamate generates sodium pyroglutamate, which has little effect on human body.
MSG was discovered in 1909 by Japan Ajisen (Ajisen) Company and applied for a patent. The appearance of pure monosodium glutamate is white crystalline powder.
Monosodium glutamate has no direct nutritional value to human body, but it can increase the flavor of food, arouse people's appetite and help improve the digestibility of food. ? Sodium glutamate, the main component of monosodium glutamate, also has the function of treating chronic hepatitis, hepatic coma, neurasthenia, epilepsy, gastric acid deficiency and other diseases.
