1 How to preserve live crabs If crabs are not in a hurry to eat after they are bought, the first step is to put them under the tap and let them suck some water. Then put it in the freezer. The temperature of the refrigerator is set at about 5℃. Because the crab will reduce its metabolism in a low temperature environment and be in a dormant state, it can avoid the physical consumption of the crab and prolong its life. After putting it away, we covered the crab with a wet towel. The function of covering wet towel is because crabs like wet environment and can keep moisture.

2. Preservation method of cooked crabs: air-cool the steamed crabs, put them in fresh-keeping bags after air-cooling, and then put them in the freezer of the refrigerator for freezing, or they can be preserved for a long time. Take it out and steam it when you want to eat it, but it is not recommended that you leave it for too long, because it will affect the taste of crabs and lose their delicious taste.
