Like seasonings often used in daily life, oyster sauce is extracted from oysters, and sugar comes from sugar cane and sugar beet. There are many sources of salt, including sea salt, lake salt, well salt and rock salt. But the above sources are all natural. Although synthetic food additives should be added in the production process, they basically meet the standards of human health food. Let's talk about it mainly. Very controversial. Now in people's minds, there are a lot of chicken essence and monosodium glutamate that people don't eat at home and don't prepare in the kitchen. The main component of monosodium glutamate is sodium glutamate. It was first invented by a Japanese chemist and is called "flavor essence". Extract from kelp. As a delicious substance and flavoring agent, it is used to flavor dishes. In China in 1930s, factories were established and mass-produced.
More than 20 years ago, everyone prepared a pack of monosodium glutamate in the kitchen at home, and put a little when cooking to make the dishes delicious. However, in recent years, with the improvement of people's living standards, health awareness has been continuously improved, and eating chicken essence or monosodium glutamate is considered harmful to health. So what's the difference between the two? How to use it in daily life? Although monosodium glutamate was first extracted from food, it was later obtained by biological fermentation for popularization and mass production. Glutamate is an essential amino acid for human body. It is widely found in all kinds of foods, and its function is refreshing, so it is safe. Since it is safe, why do some people have doubts that eating monosodium glutamate will affect their health? In fact, eating in moderation will not do harm to health, but it is just excessive.
This is because if sodium glutamate is eaten in the stomach, it will react with gastric acid to produce glutamic acid and sodium chloride. Sodium chloride is also the salt we often eat. Eating too much monosodium glutamate means eating too much salt. Excessive salt in the human body will lead to a series of chronic diseases such as hypertension. There is also a criticism of monosodium glutamate, that is, after adding monosodium glutamate to food and heating it at a high temperature of 120 or more, it will produce "sodium pyroglutamate", which is said to be a carcinogen. However, after various experiments, there is no evidence that sodium pyroglutamate is harmful to human health. Therefore, it is proved that monosodium glutamate is a safe condiment. As long as we pay attention to the correct use method: 1, put monosodium glutamate after cooking, otherwise it will lose its flavor due to high temperature. 2. The dosage should be controlled within the amount of salt, and the amount of salt should be reduced appropriately. 3, cold dishes, meat and eggs, mushrooms, no monosodium glutamate; Dishes with vinegar and sugar don't need monosodium glutamate.
The main component of chicken essence is monosodium glutamate. Because of the addition of nucleotides, it tastes like chicken. Or use nucleotides instead of chicken powder. According to the industry standard of chicken essence seasoning, the overall components of chicken essence are: sodium glutamate, nucleotide, salt, sugar chicken powder, starch, spices, essence, preservative and so on. Chicken essence is more widely used than monosodium glutamate in terms of usage. Almost all dishes are ok, as long as you like. And there is no strict requirement on the dosage, just because it contains 10% salt, the dosage of chicken essence should be reduced as appropriate. In fact, this is also a worrying "invisible salt" hazard. Conclusion MSG is safe and safe to eat. Relatively speaking, chicken essence is more harmful than monosodium glutamate. After all, more chemical additives were added. In fact, the greater harm lies in being abused by cooking.
After people tasted the sweetness of cooking with monosodium glutamate, they soon became dependent. All problems in dishes and cooking are solved with monosodium glutamate seasoning. Seasonings such as monosodium glutamate are regarded as a panacea to save the taste, which leads to excessive use. Not only is the taste spoiled, but it tastes bad without monosodium glutamate. It is also found that eating too much will make you thirsty and easily lead to a series of diseases. In fact, it is not only the problem of monosodium glutamate, but also the "sodium" in many seasonings used for cooking. That is, salt, the result of long-term excessive consumption. Therefore, although cooking is delicious, it should not be overdone, with all kinds of seasonings. Everything should be moderate.
