Hairy crabs always like to eat the rotting carcasses of animals and plants, so they contain a lot of bacteria and viruses. Therefore, after the crab dies, the microorganisms will reproduce in time, so it is easy to deteriorate. Therefore, after the crab dies, the microbial content rises rapidly, which is the main reason why the dead crab can't eat. And even if it is just dead, it is recommended not to eat more after high temperature treatment.

Hairy crabs are unique fresh water products in China. Their contents of free amino acids and nitrogen-containing compounds are high, and their meat quality is loose, which provides favorable conditions for microbial growth. Moreover, all Eriocheir sinensis grow in river water, and their living environment is suitable for microbial growth, which leads to a high total number of colonies in and out of fresh Eriocheir sinensis. Because crabs are different from fish. If they are fish, they can still be eaten as long as the meat is not spoiled. But for crabs, they are omnivorous animals.

Preservation method of hairy crabs

If the crab is not in a hurry to eat after it is bought, first put it under the tap to let the crab absorb some water, and then put it in the freezer of the refrigerator. Remember that it is the freezer, not the freezer. The temperature of the freezer is set at about 5 C. Because the crab is in a low temperature environment, it will reduce its metabolism and be in a dormant state, so that it can avoid the physical consumption of the crab and prolong its life.

After putting it away, cover the crab with a wet towel. The function of covering the wet towel is because crabs like wet environment, which can keep moisture. In this way, crabs can be kept alive for about 15 days, but the towels must be kept moist, but it is recommended that crabs eat fresh ones.
