One of the sodium salts - sodium glutamate is used as a condiment, and the commodities are monosodium glutamate and monosodium glutamate.
For pharmaceuticals, food additives, nutritional fortifiers
For biochemical research, medicinally for hepatic coma, preventing epilepsy, reducing ketonuria and ketosis.
Salt substitutes, nutritional supplements, umami agents (mainly used for meat, soups and poultry, etc.). It can also be used as a preventer for the crystallization of magnesium ammonium phosphate in canned shrimp, crab and other aquatic products. The dosage is 0.3% to 1.6%. According to my country's GB2760-96 regulations, it can be used as spice.
L-glutamic acid is mainly used in the production of monosodium glutamate, spices, and as salt substitutes, nutritional supplements and biochemical reagents. L-glutamic acid itself can be used as a drug, participating in the metabolism of protein and sugar in the brain, and promoting the oxidation process. This product combines with ammonia in the body to form non-toxic glutamine, which reduces blood ammonia and relieves the symptoms of hepatic coma. It is mainly used to treat hepatic coma and severe hepatic insufficiency, but the curative effect is not very satisfactory; combined with antiepileptic drugs, it can still treat petit mal seizures and psychomotor seizures. Racemic glutamic acid is used in the production of medicines and also as biochemical reagents.
