Let's take a look
……
<h1 class="pgc-h-arrow-right" Data-track="30" What is > oyster sauce made of? </h1>
In essence, oyster sauce is a condiment made from oysters (oysters) as raw materials, and is added to dishes (soups) to enhance the umami taste. From the perspective of the limitation of the national standard, oyster sauce is a condiment made by using the juice after oyster cooking for concentration or directly enzymatic digestion of oyster meat, and then adding salt, sugar, starch or some other raw materials and additives.
If the quality of oyster sauce is relatively high, it will contain a certain amount of amino acids, mineral zinc, taurine and other nutrients, adding dishes can not only properly supplement nutrition, but also enhance the taste.
<h1 class="pgc-h-arrow-right" data-track="88" > oyster sauce really causes cancer? </h1>
There are two main claims on the Internet that oyster sauce causes cancer, is there any scientific basis for it? Let's make it clear one by one...
I. The "carcinogenic threat" of unreasonable storage of oyster sauce
Oyster sauce contains more than 18 kinds of amino acids, a variety of mineral trace elements, esters, organic acids and other substances. If the oyster sauce is stored at room temperature for a long time after the lid is opened, it is easy to decompose oxidation, increase the pollution of harmful microorganisms, and it is easy to deteriorate.
Therefore, after the oyster sauce is opened, the reasonable storage method is to put it in the refrigerator (0-4 ° C) for refrigeration, if it is stored at room temperature for a long time (especially in the kitchen with a higher temperature), it will undoubtedly increase the risk of its decay and mildew, then it is possible to produce harmful substances such as aflatoxin and increase the risk of carcinogenicity.
Therefore, when buying oyster sauce, try to choose a small bottle of oyster sauce, shorten the storage time, and be sure to refrigerate it after opening the lid, and eat it as soon as possible.
Second, the "carcinogenic threat of sodium glutamate" in oyster sauce
Internet rumors that "oyster sauce contains a certain amount of sodium glutamate, sodium glutamate when heated will produce sodium pyroglutamate, and sodium pyroglutamate is a carcinogen, so once oyster sauce is heated, it will cause cancer", then, is this statement true?
Like monosodium glutamate and chicken essence, oyster sauce also contains a certain amount of sodium glutamate (fresh substance), sodium glutamate when heated to more than 120 ° C, it is indeed possible to produce sodium pyroglutamate, but this substance does not cause cancer to the body, but after heating will lose its umami taste.
Because of this, we recommend that you add fresh condiments before starting the pot, which can meet the needs of umami and do not produce rumored harmful substances.
<h1 class="pgc-h-arrow-right" data-track="89" > what to look out for when buying oyster sauce? </h1>
1. Purchase through formal channels
Relatively speaking, choosing formal channels and purchasing condiments such as oyster sauce produced by well-known brand manufacturers has a higher safety factor of the product, and some small workshops produce and processed foods that are prone to safety risks.
2, pay attention to the content of oyster juice
When buying oyster sauce, you can pay attention to the oyster juice content on the label, although the national standard does not mandate that the manufacturer must label the oyster sauce content, but if this "amount" exists, it proves that this oyster sauce is still very high-quality and can be prioritized. As the name suggests, the higher the content of oyster juice in oyster sauce, the better its quality (tends to be pristine).
3. Pay attention to the date and ingredient list
First, the closer the purchase date to the production date of the product, the higher its freshness and better quality.
Second, pay attention to the ingredient list of food, make it clear that the order of raw materials in the ingredient list is sorted according to the actual amount of addition, if the oyster sauce is not ranked first and second in the ingredient list, you need to seriously consider the quality of this oyster sauce.
Sum up
When people use oyster sauce on a daily basis
Be careful
Try to add as much as possible
Refrigerate after opening the lid
Oyster sauce is delicious
But it is also a "salty big household"
Everyone must eat in limited quantities
Add oyster sauce at the same time
Also reduce the amount of soy sauce and salt added
As for the statement that "oyster sauce causes cancer"
Don't take it lightly
Be sure to look at it scientifically
Do not believe in rumors, do not spread rumors, do not create rumors
