Extended Preservation Method:

1. Fish can be kept fresh by cabbage: take a cabbage with roots, dig up the cabbage heart, then put the fish meat in the dish, wrap the fish tightly with vegetable leaves and vegetable gangs, and then tie the vegetables with a rope and put them in a cool place.

2. The preservation of loaches can be washed with water first, put into a bag that does not leak, and then fill the bag with some water and put it in the freezer of the refrigerator, so that the loaches are in a state of hibernation, and the loaches can be stored for a long time, and the loaches will not die.

3. The preservation of crabs can be put in containers such as large-mouth urns or pottery jars, spread a layer of mud on the bottom, put in an appropriate amount of water, and then put the crabs in and move them to a cool place, and you can properly feed some sesame seeds or eggs with rice wine.

4. The preservation of shrimp can be cleaned first, then blanched with boiling water, and then put in the refrigerator.

1. The freezing time of marine fish and seafood is generally about 1 day.

2. If the shrimp and crab are alive, they can be stored for about 3-5 days, and if they have died, the significance of cryopreservation is not great, because the taste and meat quality of the shrimp and crab will decline after death. Mussel shellfish can be frozen for about 1 week.

3. Most of the seafood is high protein, and the protein decomposition and ripeness are very fast, if it is fresh seafood, it will not survive long after leaving the water, and it will generally die after a long time, and it is particularly easy to deteriorate and rot after death, exuding a foul smell; Dried seafood can be stored for a long time as long as it is stored properly, but if it is not stored properly, it may cause resurgence, mildew, insects and other phenomena after a long time.

1. For fresh seafood, it can generally be stored for one day in summer, and it will be longer in winter, about three days, if it is dried seafood, the storage time is relatively long.

2. Many times, seafood will be stored in foam boxes, but the temperature control effect of many foam boxes is not good, once it exceeds 4 degrees Celsius.

The storage time will be greatly reduced.

3. If you want to keep it fresh, do a good job of controlling the temperature between 0 and 2 degrees Celsius, and if conditions permit, you can put some crushed ice or frozen ice glue in the foam box.

As far as fresh fish is concerned, before putting it in the refrigerator, it is necessary to do some processing, remove the internal organs and scales, wash it, cut it into pieces, and pack it in a plastic bag, so as to avoid the spread of the fishy smell of fresh fish. The frozen fish can be stored directly in the freezer, and it is best to be quick-frozen, but it should be noted that after the frozen fish is thawed, it is not suitable for long-term storage in the refrigerator.

For the storage of shrimp, the shrimp should be washed with water, put into a metal utensil, injected with cold water, and put into the freezer to freeze; After freezing, take it out, leave it at room temperature for a while, and pour out the frozen shrimp pieces; After packaging in a plastic bag, it is advisable to store it in the freezer.

Generally, seafood can be stored in the refrigerator for a long time, but cooked fish food can not be stored in the refrigerator for too long, which will affect the taste, and at the same time, it must be sealed before being put in the refrigerator, otherwise the refrigerator will be full of odors.
