Hairy crabs are best kept in the refrigerator. The freezing layer temperature of the refrigerator will be relatively low, which is easy to freeze the hairy crabs to death, which will directly affect the consumption of hairy crabs. When live hairy crabs are put into the refrigerator, they should be put into the refrigerator freezer, which can be stored for more than three to five days. Hairy crabs are fresh aquatic products, which can be stored for a short time after leaving the water, and the purchased quantity can be eaten in about three days. If it's a dead hairy crab, don't eat it. It's easy to be poisoned.
Hairy crab is a kind of river crab. The scientific name of river crab is Eriocheir sinensis. From Liaoning and Henan to the Pearl River in the north of China, it is widely distributed along the long coastline. Among them, the hairy crabs produced by Taihu hairy crabs, Gaoyou hairy crabs and Yangcheng hairy crabs in the lower reaches of the Yangtze River are the top grade. The output of the Yangtze River system is the largest and the taste is the most delicious. Generally speaking, hairy crab refers to the Chinese mitten crab of the Yangtze River system. Now introduced to the Great Lakes, hairy crabs have been cultivated. In the past, hairy crabs produced seedlings in the coastal waters of the Yangtze River Estuary. After growing into young crabs, they migrated against the Yangtze River and grew in the branches of lakes, rivers and ports in the lower reaches of the Yangtze River. The name of hairy crab comes from Wu dialect.
If the hairy crab is used within one and a half days, it can be washed or cut into two sections, put it into a plastic bag, tie the mouth of the bag tightly, and store it in a place with low temperature in the refrigerator. If it is frozen, the hairy crab must be cooked, cooled to room temperature, packaged in a fresh-keeping bag, tied tightly at the mouth of the bag, and placed in the freezer for 1 month.
