1, oyster sauce is best stored in cold storage after opening, and oil consumption after opening is easy to mildew and deteriorate at room temperature. Oil consumption is a very common umami seasoning, which is delicious and suitable for cooking all kinds of dishes. However, because edible oil is rich in nutrients, it is easy to oxidize and decompose at room temperature, which leads to its flavor change.

2. Oyster sauce is a delicious condiment. Compared with other condiments, it is easy to deteriorate after opening, especially when stored at room temperature, and it is easy to be moldy. Therefore, the general oil-consuming bottles will be marked with the sign "Please refrigerate after opening", and refrigeration can extend the shelf life of oil consumption.

3. The main components of oyster sauce are water, oyster and starch, and its protein, fat and carbohydrate components are relatively high. These components are easily oxidized and decomposed at room temperature, resulting in thinner texture and weaker flavor. Therefore, it is best to keep it in cold storage after oil consumption.
