I. Composition
The main component of monosodium glutamate is sodium glutamate, which is also the trade name and general name of sodium glutamate. It is also called flavor powder, flavor element, sodium glutamate and sodium glutamate. It is a flavor agent.
It can stimulate taste buds and increase the flavor of food, especially meat and vegetables, and is often added to soup and meat products. It has little direct nutritional value to human body, but the glutamic acid it provides can be combined with blood ammonia to detoxify, which is used to treat patients with hepatic coma in clinic. Glutamate has two acidic groups, and monosodium glutamate is delicious.
Second, the nutritional value
Monosodium glutamate has important physiological functions in the body. Glutamate is not an essential amino acid for human body, but it participates in many metabolic processes, so it has high nutritional value. In human body, glutamic acid can combine with blood ammonia to produce glutamine, which can relieve the toxic effect of ammonia produced in tissue metabolism and can be used as an auxiliary drug to treat liver diseases. Glutamate is also involved in brain protein metabolism and glucose metabolism, which is beneficial to improve and maintain brain function.
Extended data
Glutamate is widely distributed in animals and plants and is a natural nutrient in food. After eating glutamic acid, 96% is absorbed by the body, and the rest is excreted with urine after oxidation. Although glutamic acid is not an essential amino acid for human body, it can transfer amino groups with ketoacids in nitrogen metabolism and synthesize other amino acids.
Glutamate can reduce toxins in the blood. When liver function is damaged, the ammonia content in blood increases, causing serious nitrogen metabolism disorder and leading to hepatic coma. Glutamate can interact with ammonia and reduce the ammonia content in blood.
In addition, brain tissue can only oxidize glutamic acid, but not other amino acids. Glutamine can play an energy role in brain tissue when glucose supply is insufficient, so glutamic acid is necessary to improve and maintain brain function. In addition, it can be used to prevent hepatic coma and epilepsy in medicine, and can also be used as a brain nutrient.
