How is your oyster sauce preserved? Recently, discussions on the Internet about "should I put oyster sauce in the refrigerator" have been on the hot search.
When a netizen was checking the condiments at home, he opened the bottle and found that the oyster sauce was moldy and covered with hair.
Many people have bought oyster sauce without reading the instructions carefully. On the packaging of oyster sauce, it is generally stated that "should be stored in refrigeration after opening" !
Someone has just cooked and put a lot of dishes, but I don’t know the result, but it is moldy...
Why does oyster sauce mold at room temperature?
Oyster sauce is used by more and more families as a condiment. As for the reason why oyster sauce is moldy, it depends on its composition.
In addition to oyster sauce, these should also be stored in the refrigerator!
China Agricultural University Food Biotechnology PhD Liu Jingjing published an article in Popular Science China in 2021, reminding that these condiments should be stored in the refrigerator after opening the lid:
1. Fermented condiments
such as fermented bean curd , Tempeh, soy sauce, fish sauce and shrimp paste, etc., these condiments will be introduced into the production process in the current production process, and the subsequent preservation treatment can not completely kill the contained microorganisms, so they can still maintain the biological active.
With the extension of shelf life and the change of room temperature, the microorganisms in condiments will increase by geometric orders, and the products will gradually show irreversible deterioration.
2. Condiments containing eggs, milk, fruits and vegetables
such as mayonnaise , salad dressing, tomato sauce, peanut butter, chili sauce, etc. The higher the storage temperature or the longer the storage time of such condiments Longer, the more serious the degree of non-enzymatic browning.
They also usually contain high fats, which are prone to fat oxidation during storage. When a hala taste is produced, the generated aldehydes, ketones and acids will destroy fat-soluble vitamins .
