Recently, Xiao Jiu discovered that many people in his relatives were reposting an article titled "Can't Eat! The temperature exceeds 100 ℃, MSG will produce carcinogens-sodium pyroglutamate. I wanted my mother to calm down. When I asked for confirmation, she didn't expect her hands to be so fast that she threw away the MSG at home early.
It seems that Benjiu's hand speed is still not as fast as "rumors"! In order not to let this news confuse more people, Xiao Jiu is coming to refute the rumors again!
Rumor 1: MSG is synthetic and toxic
Usually stir-fry and stew, put a little MSG in, the taste will really become fresh. In order to let people eliminate their grievances about MSG, some businesses still use slogans such as "natural" and "no additives" to attract consumers to buy. So, how does the umami taste of MSG come from?
MSG's scientific name is sodium glutamate, which is the sodium salt of glutamate . Many proteins contain glutamate, but the glutamate bound to the macromolecular protein has no umami taste. Only by disintegrating protein, freeing glutamate, and then stimulating specific taste receptors on the taste buds of the tongue, can umami taste be produced.
The discovery of umami taste dates back to 1909. At that time, a Japanese company discovered that sodium glutamate produced by the action of microbes using corn, wheat and other grain raw materials can make food show umami taste. Applied for a patent. In other words, MSG is not synthesized, but produced by microbial fermentation. The starch in the food material is converted into glucose, and the glutamate-producing bacteria is used as a fermentation tool to produce glutamate through fermentation, and then synthesize sodium glutamate to obtain monosodium glutamate.
Because monosodium glutamate is a cheap food additive, many people have a "trust crisis" in monosodium glutamate, thinking that it is chemically synthesized and harmful to humans. This is a rumor, don't believe it.
Rumor 2: Over 100°C, MSG produces carcinogen "sodium pyroglutamate"
As a commonly used condiment, MSG has long been studied by scientists, so the world The Health Organization, the U.S. Food and Drug Administration, and the Chinese Dietary Guidelines all classify MSG as the "safest" category.
Then, how did the rumor that "MSG produces carcinogen sodium pyroglutamate" over 100°C? It turned out that experiments proved that sodium glutamate in MSG may indeed produce sodium pyroglutamate when heated to above 120°C. But sodium pyroglutamate is not a legendary carcinogen. So far, there is no scientific evidence that sodium pyroglutamate can cause cancer.
MSG is very fresh, but not everyone can eat it.
MSG can enhance the umami taste of food, but it is not suitable for everyone. For example, children, the elderly, people with high blood pressure, diabetes, etc. should eat less or no MSG.
Because MSG contains more sodium components, on the one hand, a high-sodium diet will affect the growth and development of children; on the other hand, a high-sodium diet can easily lead to high blood pressure, and may also increase the risk of type 2 diabetes and coronary heart disease. Risk of illness. Therefore, you should put less MSG. When consuming MSG, reduce the amount of salt and soy sauce.
Can MSG be eaten? can! Teach you to eat correctly
Some people say that MSG is good for the body, some people say that MSG is not edible, everyone is trapped, can you still eat MSG? Of course you can eat it, but you have to learn to eat it correctly.
One is to use salty but not sweet . The umami taste of MSG can only be displayed in savory dishes. If MSG is added to sweet dishes, not only can it not increase the freshness, but it will inhibit the original taste of sweetness and produce a peculiar smell.
The second is to put it just before the pot. The instructions on the MSG package all say "Recommend to put it out of the pan". This is because if MSG is put in advance, sodium glutamate will be converted into sodium pyroglutamate, which will make the food lose its flavor.
Three is no more than 1.8 grams per day. In 2017, the European Food Safety Agency released the latest evaluation report on the food additives glutamate and glutamate: The safe intake of glutamate (and its salts) for humans is 30 mg per kilogram of body weight per day. In other words, for a 60 kg adult, it is equivalent to no more than 1.8 grams per day.
In those years, the rumors about MSG, MSG said "I don't remember this pot." After reading this article on the rectification of MSG, ask your parents to pick up the discarded MSG!
