Chicken essence, monosodium glutamate eaten too much is harmful to people.

Chicken essence contains sodium glutamate with the highest solubility under the condition of 70℃~90℃. When heated above 120 ℃, sodium glutamate in chicken essence will become coked monosodium glutamate, not only lose the fresh taste, but also a certain degree of toxicity. Children who ingest it for a long time can easily lead to a dulled sense of taste.

Too much MSG can lead to excessive sodium intake, which can lead to edema, elevated blood pressure and other diseases. Once the body sodium intake is too much, will lead to the body osmotic pressure increases, blood volume increases, resulting in increased burden on the heart. It will hinder the body's absorption of calcium, magnesium and other minerals. In particular, the combination of glutamic acid and zinc in the blood can not be absorbed and utilized by the body, which will indirectly lead to zinc deficiency.

Monosodium glutamate (MSG) can generate monosodium pyroglutamate (monosodium pyroglutamate) when heated at high temperatures for long periods of time, which is believed to be carcinogenic and unhelpful to the human body. Excessive use of MSG is also thought to lead to: retinal damage and thus cause vision loss; inhibit nerve function and thus affect the development of children.

Expanded Information

Monosodium glutamate (MSG) is only a flavor enhancer in our dishes, and can be consumed in moderation when we feel a loss of appetite. The World Health Organization's intake of MSG is 120 mg/kg of body weight per adult per day, so it would be best not to exceed 6 grams for a 50 kg person.

No MSG in marinades and coleslaw. Because as soon as you put MSG, it tends to coat the surface of the food, preventing other flavors from penetrating into the food, so it tastes like a single, dull flavor presented only by MSG.

Chicken essence and monosodium glutamate are appropriate in the dishes out of the pot put, when the temperature at 90 ℃ up and down, chicken essence of monosodium glutamate can not only be fully dissolved, but also highlight its unique fresh flavor. Chicken essence is highly hygroscopic and more susceptible to microbial contamination than MSG, so it should be stored in sealed bottles to avoid moisture. It should not be stored for a long time after opening the lid, and should be covered tightly after each use.
