2. Thaw at low temperature. Put the prepared brackish water in the refrigerator for about 30 minutes. Put the blue crabs in cold brackish water, and put them in an air-conditioned room or a cool place until the blue crabs regain their vitality.
The best way to preserve live blue crabs is 1. Cold storage is a common method to preserve live blue crabs. Generally, the blue crab is soaked in light salt water for about 5 minutes, then put in the refrigerator and covered with a wet towel. It can be stored in cold storage for about 3 days. If it is too long, the blue crab will freeze to death.
2. If the culture time in light salt water is long, the blue crab can be cultured in light salt water. Put the blue crab in a deep bucket, add a little light salt water to ensure that it does not pass through the mouth of the blue crab, loosen the lanyard of the blue crab, and put some food such as apple cores in the bucket, which can be cultured for about 1 week.
Can the blue crab still eat when it freezes to death? Yes
If the blue crab is frozen to death, the temperature of the blue crab is always below zero, and the bacteria grow slowly in this environment, which has certain antibacterial effect. Therefore, the blue crab can still be eaten after freezing to death, but it should be noted that the blue crab cannot be taken out and thawed before being put back.
Do frozen crabs need to be thawed? Yes
Frozen crabs need to be thawed before eating. After freezing, the water in the crab turns into ice. If cooked directly without thawing, there will be a great difference in maturity between the outside and the inside of the crab, which will lead to the aging of the outer meat of the crab and affect the taste.
