What is the nutritional value of monosodium glutamate?

1. MSG 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; 2. 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. Common name: monosodium glutamate (C5H8NO4Na) is light and sour. Efficacy: nourishing, appetizing and helping digestion. Suitable for patients with neurasthenia, cerebral hypoplasia and schizophrenia; It is suitable for patients with hepatic coma and severe liver dysfunction to taste monosodium glutamate. Suitable for patients with gastric ulcer and insufficient gastric juice; Suitable for people with mental retardation and memory loss after cerebral hemorrhage; Suitable for minor episodes and psychomotor authors; Suitable for people with poor appetite and loss of appetite; Suitable for eating when vegetables or soup are about to be cooked. Avoid eating and cooking for a long time after adding msg. In the weekly quality report of CCTV- news channel on June 7, 2007, nutrition expert Wu said that the main component of monosodium glutamate was sodium glutamate, clarifying that "monosodium glutamate has absolutely no harm to human health". The chemical name of monosodium glutamate is also called sodium glutamate, which is an amino acid and the final decomposition product of protein. In strong alkali solution, disodium glutamate can be produced, and the umami taste is gone. If the water solution is heated to 120℃, some sodium glutamate can be dehydrated to produce sodium pyroglutamate, which is even worse. According to research; Monosodium glutamate can stimulate people's appetite, improve the absorption ability of other foods, and has a certain nourishing effect on the human body. Because monosodium glutamate contains a lot of glutamic acid, which is an amino acid needed by human body, 96% of which can be absorbed by human body and form protein in human tissues. It can also combine with blood ammonia to form glutamine which is harmless to the body and alleviate the toxic effect of ammonia produced in the process of tissue metabolism. It can also participate in brain protein metabolism and glucose metabolism, promote the oxidation process, and play a good role in the normal activities of the central nervous system. Therefore, it is reported that it is used to prevent hepatic coma, taking 3 grams of monosodium glutamate each time, 1 three times a day; To prevent and treat minor seizures, adults take 2g daily, and children take 1g daily, three times a day; Cerebral hypoplasia, take L ~ 1.5g daily and 1.5g three times a day. Monosodium glutamate is a widely used condiment, which can be decomposed into glutamic acid and tyrosine after ingestion, which is beneficial to human health.
