The main component of monosodium glutamate is sodium glutamate, which is easily converted into sodium pyroglutamate when it exceeds 120℃, but sodium pyroglutamate is harmless to human body, but it just has no umami taste. Monosodium glutamate will decompose and be destroyed when it is heated to 270℃. Under the cooking temperature of general food, the performance of monosodium glutamate is stable, so there is no need to worry about deterioration and toxicity.

The freshness of monosodium glutamate is extremely high, and it can still be distinguished when it is dissolved in 3000 times of water, but its umami taste can only be shown when it coexists with salt. Therefore, monosodium glutamate should not be put in salt-free dishes (such as beets). Attention should also be paid to temperature and dosage when using monosodium glutamate. The optimum temperature for dissolution is 70℃ ~ 90℃.

When the dishes are acidic or alkaline, monosodium glutamate (such as sweet and sour dishes) should not be used. It is not advisable to put monosodium glutamate in dishes with excellent flavor (such as scallops and ham) or made of high-grade clear soup (such as clear soup swallow).

Comparison with chicken essence

Monosodium glutamate is a delicious substance, the main component of which is sodium glutamate, and its trade name is monosodium glutamate, also known as monosodium glutamate. Generally, monosodium glutamate is extracted and refined by microbial fermentation of rice, corn, wheat, sweet potato and other food crops to obtain sodium glutamate that meets the national standards.

Chicken essence is a compound condiment, and its main components are monosodium glutamate (40%) and salt. In addition, the chicken essence also added fresh-keeping agent nucleotides, chicken extract, starch, puffing agent, essence, pigment and so on.

A small amount of nucleotides can make monosodium glutamate fresh by 20 to 30 times, but a lot of salt and starch are added during production, so the umami taste of chicken essence has not improved much compared with monosodium glutamate, and the dosage is similar in actual use.
