Because seafood itself is a food with heavy smell, it is easy to rot overnight, and many bacteria will breed after overnight, and seafood will also degrade at this time.

Seafood, also known as seafood, easily produces protein degradation products overnight, including fish, shrimp, crab, shellfish, mollusks and other categories. Although marine life such as kelp is often cooked into food, seafood is mainly for animals, and most edible marine life can be called seafood. In a narrow sense, only fresh seafood can be called seafood. Seafood can be divided into live seafood, chilled seafood, frozen seafood and dried seafood.

Fresh-keeping method of seafood

1, most marine fish are frozen, so they should be frozen in the refrigerator. Don't put them in the freezer after thawing.

2. If it is fresh fish, it is necessary to remove the scales and internal organs of the fresh fish, wash and drain them, then cut them into small pieces, wrap them in fresh-keeping bags or tin foil to prevent the fishy smell from spreading, and finally put them in the freezer of the refrigerator for preservation.

3. mussel seafood should be washed with clear water first, then put a basin of clear water and a spoonful of salt in it, soak for 2 hours, spit out the sediment and put it in the refrigerator for refrigeration.

4. If it is shrimp, you can wash the shrimp with clean water and put it in a metal basin, then put water in the basin, finally put it in a freezer, freeze it into pieces, take it out and leave it for a while, then pour out the frozen shrimp pieces, seal them with fresh-keeping bags, and then put them in a refrigerator for frozen preservation.
