: chicken essence Vs monosodium glutamate! Who is more nutritious and safe

Many consumers believe that monosodium glutamate is a chemical synthetic substance, which is not only nutritious, but also harmful to the health if eaten frequently. Chicken essence, on the other hand, is made of chicken as the main raw material, which is not only nutritious but also safe. As a result, we can often see that some people are afraid to avoid monosodium glutamate when cooking, but they feel that they can put as much and whenever they want to put chicken essence. In fact, chicken essence is not much different from monosodium glutamate. ?

: Chicken essence contains 4% monosodium glutamate

Although most chicken essence packages say "made from superior fat chicken" and "really superior chicken", it is not a natural condiment mainly made from chicken, chicken bones or its concentrated extract as we imagined. Its main components are monosodium glutamate and sodium glutamate. Among them, monosodium glutamate accounts for about 4% of the total components, and there are also substances such as sugar, chicken or chicken bone powder, spices, inosinic acid, guanylic acid, chicken flavor essence and starch.

The flavor of chicken essence is fresh mainly because of the role of monosodium glutamate. In addition, inosine monophosphate and guanosine monophosphate are both fresh-keeping AIDS, and they also have the effect of seasoning. Moreover, their combination with sodium glutamate can make the umami taste of chicken essence softer, the taste more rounded and full, and the fragrance more intense. As for the realistic chicken flavor in chicken essence, it mainly comes from chicken and chicken bone powder, which are extracted from fresh chicken and chicken bone. The use of chicken flavor essence can also make the "chicken flavor" of chicken essence thicker; The function of starch is to make chicken essence granular or powdery.

: which is more nutritious, chicken essence or monosodium glutamate?

monosodium glutamate is mainly extracted from rice, corn and other grains or molasses by microbial fermentation. Its main component is sodium glutamate, which is a kind of amino acid and the main component of protein. The composition of chicken essence is more complex than monosodium glutamate, and its nutrition is more comprehensive. Besides sodium glutamate, it also contains many vitamins and minerals.

However, chicken essence, no matter how nutritious it is, is only a condiment, which cannot be mentioned in the same breath as chicken. Moreover, according to the investigation of Guangdong Consumer Council, it is found that the content of protein is different among different brands of chicken essence in the market, which is mainly related to the content of chicken powder or chicken bone powder.

: The safety is similar to that of monosodium glutamate

Many people are afraid to eat monosodium glutamate, mainly for fear that it will produce certain carcinogens. However, experts in food additives from the Food and Agriculture Organization of the United Nations and the World Health Organization believe that under normal circumstances, monosodium glutamate is completely safe and safe to eat, just don't heat it above 12℃, otherwise the sodium glutamate in it will lose water and become sodium pyroglutamate, producing carcinogens. Because chicken essence also contains a certain amount of sodium glutamate, its safety is similar to that of monosodium glutamate, and attention should also be paid not to heat it at high temperature for a long time.

In addition, since chicken essence itself contains about 1% salt, if chicken essence is used in cooking and soup, the amount of salt used must be reduced. Chicken essence also contains nucleotides, and the metabolite of nucleotides is uric acid, so gout patients should eat less.
