1, refrigerator preservation of crabs, crabs are fresh aquatic products, out of the water after the preservation of a shorter period of time, the number of purchases can be eaten in about 3 days of time to save the crabs is relatively simple: choose vigorous crabs, the crab's feet and pincers bundled up to reduce the physical exertion of the crabs, and then placed in the refrigerator freezer, covered with a wet towel to save can be. When you eat them every day, pick the less energetic ones first, and keep the more energetic ones.

2, plastic buckets/pots to save crabs, prepare a 30-50 cm high plastic buckets or pots, because the inner wall of plastic buckets/pots is smooth and not easy to escape. Put the crabs into it, and then add water to half the height of the crab's body - mainly moisturizing, can not bury all the crabs, if the water is too deep the crabs will lack of oxygen and suffocate and die. Buckets/pots do not need to be covered, using this method of preserving crabs, hairy crabs can be preserved for more than 5 days when the temperature is not too high.

Cooked crabs that are not eaten in full can be packed into clean, airtight containers and put into the refrigerator in the cooked food section for cold storage and should be eaten as soon as possible. Whole cooked crabs should be stored in the refrigerator for a maximum of 1 to 2 days because internal organs such as crab intestines and other internal organs are highly susceptible to bacteria, and long term storage for consumption will pose a potential safety hazard. If you want to store it for a longer period of time, pick out the crab meat and crab yolk separately, put them into a clean airtight container, and then put them into the freezer for more than 1 month. Be reminded to always reheat when eating.
