1, you can wash it with clear water, put it in a basin and drop a few drops of sesame oil, which can last for a day or two.

2. If it needs to be preserved for a long time, it needs to be boiled in the shell, then the meat is taken out, wrapped in a fresh-keeping bag and frozen in the freezer.

3, preserved in shells, oysters can survive even at ordinary room temperature.

4. Take the meat out and keep it. If the refrigerator has zero-degree fresh-keeping function, it should be able to keep it for about 5 days, and the general refrigeration is 3 days.

If freezing is called chilled, put the oysters in the fresh-keeping box to freeze. Oysters themselves will have soup. Don't pour it out and freeze it together to keep the flavor. In addition, the refrigerator itself is not quick-frozen, so the freezing time should not exceed half a year, otherwise it will affect the taste.

The most commonly used method is freezing in the refrigerator, which is a long-term preservation method. But if you only need to keep it for a day or two, besides freezing, you can also try to wash the bought oysters with water and put a few drops of sesame oil in a basin, so that you can keep it for a day or two.

However, it is best to eat oysters alive after purchase, so that they can absorb rich nutrients and taste more delicious.
