Aunt Zhou's family bought a bottle of oyster sauce last year, because of this sentence, no one eats oyster sauce when it grows hair. Aunt Zhou saw an article from the Internet, where the experts said to eat less oyster sauce and other condiments, eat more will cause cancer, and oyster sauce inside a little oyster oysters, are spices out of the umami taste, long-term eating more will produce chemical effects in the body, Aunt Zhou listened to the heart of the drum, did not dare to eat oyster sauce, after using a few times, it was placed in a corner of the stove, until moldy before throwing it away.
Oyster sauce is a condiment used to freshen up, but many people do not eat it, is it really carcinogenic?

Although oyster sauce has an oil word in its name, it has nothing to do with oil. Oyster sauce actually refers to the concentrated juice formed by boiling oyster soup, which has certain nutritional value. Oyster sauce contains oyster sauce (oysters, water, table salt), water, sugar, and sodium glutamate and other substances, of which sodium glutamate is the source of oyster sauce umami, but also the source of "carcinogenic" discussion, sodium glutamate is also the main component of monosodium glutamate.
Sodium glutamate is found in many natural foods, including tomatoes, corn, and kelp. Modern technology in order to mass production, generally with starch, molasses and other fermentation after the formation of sodium glutamate, this production process is in line with national standards. Sodium glutamate is a safe flavoring agent recognized by many authorities worldwide, including WHO, FDA, CFDA, etc.
It should be reminded that oyster sauce is not completely "harmless", and if used incorrectly, it can also adversely affect health.
<h1 class="pgc-h-arrow-right" data-track="47" > Second, making a mistake with oyster sauce may have a health risk</h1>
Oyster sauce needs to be refrigerated after opening the lid, it is not resistant to high temperatures, and it is easy to deteriorate after opening the lid without refrigeration.
Liu Jingjing, a doctor of food biotechnology at China Agricultural University, explained that because oyster sauce contains sugar, starch, rich trace elements and amino acids, it is easy to undergo oxidative decomposition when stored at room temperature. It provides excellent conditions for the reproduction of microorganisms in the environment, so it is easy to deteriorate, and after the oyster sauce is opened, it must be remembered to refrigerate and preserve.
In addition to oyster sauce, there are many spices used in life that also need to be refrigerated, have you refrigerated these spices?
<h1 class="pgc-h-arrow-right" data-track="38" >3, not just oyster sauce, these spices should also be refrigerated</h1>
Liu Xiaoman, a master's student in social medicine and health management at Shanxi Medical University, pointed out that in our daily life, some seasonings need to be refrigerated, and some can be refrigerated or not.
To be refrigerated:
1. Fermentation condiments
Such as curd milk, tempeh, etc., such fermented products will add certain strains in the production process, and it is impossible to completely sterilize them when they are produced in our hands. Therefore, it is easy to deteriorate in a warm and humid environment, and it needs to be stored at low temperature and eaten as soon as possible.
2. Condiments containing egg milk, fruits and vegetables
Condiments such as salad dressings and ketchup need to be refrigerated after opening. The longer these condiments are stored at room temperature, the more severe the degree of non-enzymatic browning and fat oxidation.
Refrigerated or not refrigerated:
1. Wine and vinegar
These two condiments themselves have the effect of inhibiting the growth of bacteria, so it does not matter if they are not placed in the refrigerator, but pay attention to storing them in a cool and dry place. It should be noted that some wine and vinegar with other ingredients or additives are recommended to be stored in the refrigerator and consumed within 2 months after opening.
2. Soy sauce, kimchi
These foods contain high concentrations of sodium, and it is generally difficult for bacterial microorganisms to multiply, so it does not matter if they are not placed in the refrigerator. Of course, it is also possible to put it if you want to.
In addition to the need for refrigeration of oyster sauce, some points that need to be paid attention to before use, look down together.
<h1 class="pgc-h-arrow-right" data-track="39" >, put oyster sauce, avoid 3 misunderstandings
1. Avoid the use of and part of the seasoning</h1>
Oyster sauce will be fresher when added to the dish, and the taste is more pure. Therefore, when using it, it is not recommended to use it with some spicy and stimulating condiments, such as chili, star anise, soybean paste, etc., which will cover up the umami taste of oyster sauce.
In addition, the function of oyster sauce and condiments such as monosodium glutamate, chicken essence, and soy sauce is repetitive, and after oyster sauce is placed, there is no need to put these condiments.
2. Avoid excessive use
Oyster sauce can enhance the umami taste, but not the more you put it, the better, when stir-frying, you can put about 5ml each time.
3. Avoid heating for a long time
When the oyster sauce is heated to 120 degrees, sodium pyroglutamate is produced, which loses its original umami taste. In this way, the original purpose of adding oyster sauce is lost, so it is generally recommended to add oyster sauce when it is about to come out of the pan to avoid letting it be heated for a long time.
Although oyster sauce is a common condiment in life, I believe that many people do not know much about these knowledge points about oyster sauce. After reading this article, pay attention to changing some bad habits of using oyster sauce! #健康明星计划 #
