1, feed with clear water. If the bought oysters are still alive, they can be raised, put in clean water, and then put in a dry and normal temperature environment, which can be kept for about a week without deterioration.

2, the fresh-keeping box is fresh. 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. The refrigerator freezes. If you open all the oysters, you can put them in the freezer of the refrigerator. The temperature should be set at about 4~5 degrees, and it should not be too high. Otherwise, oysters will breed a lot of bacteria, thus accelerating decay and deterioration.

4, sesame oil preservation. If the oysters are still fresh, you can wash them with clear water first, then put them into the basin, and then drop a few drops of sesame oil into the basin, so that they can be kept for about two days without deterioration, but you should eat them as soon as possible.

5. pay attention. When buying oysters, don't buy too many at a time, so as not to eat them all at once and cause waste. After all, oysters are not easy to keep fresh. If they smell fishy, or the oyster meat changes color, it means that the oyster is not fresh and not suitable for eating.
