Oysters are a kind of marine shellfish, which contains a lot of water as well as bacterial microorganisms, so it is easy to die after leaving the sea water. Death and deterioration, preservation time is not long, the general oysters more common preservation method is directly placed in a cool place to save, the specific operation is as follows:

1, will be cleaned up the shell of the oyster, put into the basin.

2, and then put a layer of lightly salted water, the amount of water do not roam over the oysters, to keep wet.

3, or you can also cover the oysters with a layer of wet cloth.

4, and then put the oysters in a cool, ventilated place to save.

5, this method can usually be kept for about 1-2 days.

Note: The oyster shells of fresh oysters are tightly closed, and the mouth of the oyster shells of dead oysters will be cracked, and there will be an odor if not treated in time.

In the refrigerator under cold conditions can be very good inhibition of bacterial reproduction, but also suitable for the growth of oysters, if the oysters will be kept in the refrigerator cold storage, up to one week of survival, cold storage methods are as follows:

1, will buy back the oyster shells washed, into the basin.

2, and then take a piece of wet cloth to cover the basin surface.

3, put the basin into the refrigerator freezer to save.

4, oyster refrigeration is generally 4 to 5 degrees Celsius, to constant temperature, high temperature will breed bacteria, oyster meat will rot, low will freeze or freeze oysters; also can not be arbitrarily turned or mixed with other food shelves, so as not to shorten the preservation of time or string of flavors.

The temperature of the freezer layer of the refrigerator is lower, you can better inhibit the growth of bacteria as well as reproduction, can effectively prolong the preservation of oysters, if the preservation of the better, you can save about a month or so, but oysters to put frozen preservation of the longer the loss of its nutrients will be the more, the taste will also deteriorate. Specific freezing methods are as follows:

1, the oysters clean, into the pot to cook.

2, then remove the oyster shells, leaving oyster meat.

3, put the oyster meat in a plastic bag and keep it in the refrigerator.

4, pay attention to separate from other food storage, to avoid string flavor.

If stored properly, you can continue to eat them.

Already cooked oysters contain a lot of water as well as carbohydrates, so it is easy to breed bacteria and spoilage, it is recommended to wrap it with plastic wrap, and then put it in the refrigerator to keep it in the freezer or put it in a plastic bag and put it in the refrigerator to keep it in the freezer, it will not deteriorate, and you can still continue to eat it after heating it up. If you are afraid to put at room temperature to save, there is a change in flavor, rancidity, then you can not eat, otherwise it may cause a series of gastrointestinal reactions, such as: abdominal pain, diarrhea, nausea, vomiting, etc., once the above discomfort, and the symptoms are more pronounced, it is recommended to go to the hospital to see a doctor under the guidance of the line of symptomatic treatment.
