If oysters are soaked in water and stored directly at room temperature, they can generally be stored for about 1-2 days. If they are soaked in water and then placed in the refrigerator, they can survive for about a week at most. , because the refrigerated environment can inhibit the growth of bacteria to a certain extent and is more suitable for the living environment of oysters, so the storage time will be relatively long. Do not wash the oysters with fresh water when they are dehydrated. If there is no ice in the trunk of the car, the normal time is 8 hours under constant temperature. If the temperature exceeds 30 degrees, the oysters will open in 5 hours. If they are placed in a fresh-keeping container, It can be kept for 3 to 5 days at a temperature of about minus 8 degrees. Points to note when raising oysters temporarily: 1. Never soak oysters in fresh water or seal them in airtight plastic bags, because oysters live in salt water. For oysters arriving by air, it is best to place the oysters on special dry ice in a cool place for 3 to 4 days. 2. If the purchased oysters do not need to be stored for a long time and will be eaten soon, then put a shallow layer of water, or you can directly cover the surface with a piece of wet cloth to keep the oysters moist. If you need to preserve oysters for a longer period of time, it is recommended to add more water and soak them in water, which can extend their storage time. 3. Can oysters be soaked in tap water? If the bought oysters are to be eaten immediately, you can soak them in tap water for a few hours to spit out the sediment; if they need to be stored for a few days before eating, it is recommended to store them in light salt water or sea water, suitable for salt. The temperature is 10%-25%, and the temperature is controlled at 4-6 degrees Celsius, which is more in line with its living environment and can extend its storage time. Oysters will become thinner and thinner because oysters no longer eat after being harvested. To maintain their freshness, oysters must consume their own stored energy. In other words, the longer they are on the shore, the "thinner" the oysters will be. If they are more than 1 week old, they will become thinner. thin. Therefore, oysters should not be stored for too long. The sooner you eat them, the better.
