Crabs unfit for raw food

Special formula

Crabs generally feed on animal carcasses or humus, so the body surface, gills and gastrointestinal tract of crabs are covered with all kinds of bacteria and sludge. Crabs often carry cysts of paragonimiasis and Vibrio parahaemolyticus. If it is not disinfected at high temperature, paragonimiasis will cause lung injury after entering the human body. If Vibrio parahaemolyticus invades human body in large quantities, infectious poisoning will occur, which is manifested as intestinal inflammation, edema, congestion and other symptoms. Therefore, crabs should be steamed and cooked thoroughly, and generally heated for more than 30 minutes after boiling to play a disinfection role. Health maintenance

Pay attention to the four clean-ups when eating crabs. First, clean the crab's stomach. Crab stomach, commonly known as crab urine bag, is a triangular bone bag in the center of the front edge of the back shell, which contains dirty sand; Second, we should eliminate the crab intestine, that is, a black line from the crab stomach to the crab navel; Third, clear the crab heart, commonly known as hexagonal plate; Fourth, we should remove the crab gills, that is, two rows of soft things like eyebrows that grow in the crab abdomen, commonly known as crab eyebrows. These parts are dirty and have no edible value. Don't chew them indiscriminately to avoid food poisoning.

Method for preserving live crabs

Remember that river crabs can't go into the water. Eriocheir sinensis can't get wet. Just put it in a container and cover it with a wet towel.

Try to choose crabs with green shells. Crabs with yellow shells are not very fresh and have a short storage time. Tie it with a rope and put it in the pot. The lid of the pot is tilted a little for air and put in the refrigerator. My experience is that it won't take more than three days, because after a long time, crabs will lose weight and consume nutrition. I hope it works for you.

Just put the crabs in the refrigerator with a freezer. Crabs can't be put in the refrigerator. They can be stored in containers in the shade for 5-8 days.

Live sea crabs can be tied up directly and frozen in the freezer, which can be kept for several months. This is how the seafood in the New Year is preserved.

The correct way for hairy crabs is to put them on the dry ground like that, but in a place with a little higher humidity, such as next to the kitchen sink. It is enough to put them in water for 5 minutes every two days or so. Crabs feel sorry for each other.
