The origin of "MSG symptoms"

Eating MSG is very common in our country. Almost every household uses MSG for cooking, and chefs in restaurants cannot lack it. When cooking and making soup, just add it A small amount goes a long way to boosting the umami flavor. But in the 1980s, the so-called "Chinese restaurant disease" started in the world. People who eat Chinese food have symptoms such as headache, numb face, thirst, gastrointestinal discomfort, etc. Later, it is said that this is due to the MSG in Chinese dishes. Therefore, there is a saying that "MSG symptoms" are caused, so that some Western restaurants have signs saying "This restaurant does not use MSG" and so on, which has caused an international controversy.

The true identity of MSG:

MSG is a white crystal, also known as sodium glutamate, and its chemical name is L-glutamic acid monosodium monohydrate Compound, the English abbreviation is MSG. MSG is extracted from soy protein, wheat gluten or other protein-rich substances, and is also made from starch fermentation. MSG is a condiment and a nutritional supplement. It can be directly absorbed by the human body after eating and becomes a basic component of human cells. The national standards of the People's Republic of China stipulate that if the product name is monosodium glutamate or monosodium glutamate, its sodium glutamate content should be above 99%.

The production process of MSG:

Currently, my country mostly uses fermentation to produce MSG. First, various grains must be made into starch, then the starch must be saccharified, and bacteria must be added for fermentation. Glutamic acid is then processed through isoelectric crystallization, cooling and separation, neutralization, iron removal, decolorization, crystallization, separation, and drying to produce highly pure sodium glutamate, that is, monosodium glutamate.

How MSG produces "umami":

The important function of MSG is that it can produce "umami". There are specialized amino acid receptors in the human taste organ. When MSG is eaten by people, the amino acid receptors located on the taste buds of the tongue can make people feel the delicious umami taste. What are the effects of eating MSG on the human body?

MSG is a safe and beneficial condiment. People can consume it as they like. The United Nations Committee on Food, Agriculture and Food Additives Regulations has already decided to cancel the consumption of MSG***.

From March 17 to 22, 1987, the 19th session of the Food Additive Regulations Committee of the United Nations and World Health Organization held in The Hague, Netherlands, resolved to cancel the daily intake of 6 to 7.5 grams of monosodium glutamate (MSG). Food safety regulations. This decision means that MSG, as a food flavor enhancer, can be consumed to the extent of one's liking without any problem. After collecting a large amount of literature and experimental data, the U.S. Food and Drug Administration proposed that "under the current usage and consumption methods, long-term consumption of MSG will not cause any harm to the human body."

After decades of animal biochemical physiology research and extensive customer surveys, experts from various countries have put forward a large amount of scientific evidence to prove that MSG is one of the important nutrients needed by the human body and is present in human food and As a natural substance of the human body, MSG can be completely digested and absorbed by the human body and undergo normal biochemical metabolism.

my country’s food additive hygiene standards stipulate that MSG can be used in all types of food as a freshness enhancer. Its maximum consumption is based on normal production needs, and there is no need to propose daily allowable intake standards. The China Academy of Traditional Chinese Medicine has conducted long-term toxicity tests on Chinese MSG products, once again proving that MSG is safe.
