Seafood can't be preserved or eaten raw. If it is eaten raw and cold, you can wash it and soak it in vinegar for 10 minute, then add other condiments. Aquatic seafood, unlike meat, contains many low-temperature resistant bacteria, and protein decomposes very quickly. If it is kept in the refrigerator for a long time, the bacterial content of shrimp will increase, and protein will be partially denatured, producing amine substances, which will not reach the taste, flavor and safety of live shrimp in any case, and it is certainly not suitable for boiling. But chilled shrimps can be fried or fried at high temperature, and they can also be delicious.
If the seafood has been cooked thoroughly at high temperature, you just need to put it in the refrigerator immediately and eat it after the next meal is heated. If the seafood is not fully heated but dead, it should be put into the cold room, thawed before the next meal, and then thoroughly heated and cooked. Don't crave the fresh taste. Because the protein of seafood is delicate in texture and decomposes quickly, you should eat it within one day after taking it home, and it is not advisable to store it for a long time.
