1, frozen in the refrigerator; Wrap the oysters with plastic wrap and put some salt in the refrigerator to keep them fresh. Oysters are usually refrigerated at a constant temperature of 4 to 5 degrees Celsius. If it is high, bacteria will breed, causing oyster meat to rot. If it is low, it will freeze or freeze oysters.

2. Store in a fresh-keeping box; If oysters are left for too long, they will easily deteriorate and their taste will be greatly reduced. You can put oysters in a white foam box and add some ice cubes, which can be kept for about three days without spoilage.

3. Keep it in a container filled with seawater; Oysters can be stored in containers filled with seawater for a long time. When buying, you can ask for sea salt water from the merchants who sell oysters, and pour them into clean containers to preserve oysters after returning home. If there is no seawater, salt water can be used instead, but the shelf life is shortened.
