What Is Glutamic Acid?

Glutamic acid, also known as glutamic acid, is an acidic amino acid. The molecule contains two carboxyl groups and the chemical name is -aminoglutaric acid. Glutamate was discovered by Rissomson in 1856. It is a colorless crystal with an umami taste, slightly soluble in water, and soluble in hydrochloric acid solution. Glutamate is abundantly present in cereal proteins, and it is also abundant in animal brains. Glutamic acid plays an important role in the process of protein metabolism in organisms, and participates in many important chemical reactions in animals, plants and microorganisms. MSG contains a small amount of glutamic acid. ^[1]

Glutamate is mainly used in medicine

This product is an amino acid drug. In severe hepatitis or liver insufficiency, the liver fails to convert the link from ammonia to urea, resulting in an increase in blood ammonia and encephalopathy symptoms. The intake of glutamic acid is beneficial to reduce and eliminate blood ammonia, thereby improving the symptoms of encephalopathy.

Indication

1. Used as an adjuvant for the treatment of hepatic encephalopathy.

2. Used as an adjunct to the treatment of certain mental and nervous system diseases.

3. For the symptoms of insufficient gastric acid or hypoacidity.

Adverse reactions

Facial flushing symptoms can occur about 20 minutes after taking the medicine. ^[5]

Any food should be eaten in moderation, not for the better, and excessive consumption is naturally not healthy. From February 16 to 25, 1987, at the 19th meeting of the Joint Committee of Experts on Food Additives of the Food and Agriculture Organization of the United Nations Food and Agriculture Organization and the World Health Organization in The Hague, The Netherlands, based on the results of comprehensive evaluation of various toxicological experiments of MSG, As a flavor enhancer, monosodium glutamate is safe to eat. It has announced the cancellation of the limit on the consumption of monosodium glutamate, confirming that monosodium glutamate is a safe and reliable food additive. In terms of nutritional value, monosodium glutamate is a monosodium salt of glutamic acid, which is one of the amino acids that make up proteins. It is an important nutrient for humans and animals and has special physiological effects.

According to the 1975 American Dictionary of Nutrition and Food Technology, MSG 25 mg / kg body weight was consumed on an empty stomach, and symptoms such as headache, sweating, nausea, soft body, thirst, cheek flushing, and abdominal pain occurred after 25-35 minutes. However, these symptoms usually disappear within a few hours, so do not eat MSG on an empty stomach. Decomposed substances of glutamic acid and sodium glutamate contain very strong mutant substances. If vegetable oil and MSG are mixed together and heated for about 20 minutes, the mutant substances will increase further. Therefore, MSG should not be added during high-temperature cooking during cooking, but should be added at the end of cooking for seasoning.
