1, the taboo of eating crabs
1, crabs should be eaten alive, and dead crabs should not be eaten.
After death, the rigidity period and autolysis period of Eriocheir sinensis are greatly shortened, and the bacteria in the crab will multiply rapidly and spread into the crab meat, causing vomiting, abdominal pain and diarrhea.
The shell of the fresh crab is bluish-black, with luster, full navel and Bai Jie abdomen. However, the shell of the dying crab is yellow, and the crab's feet are soft, so it is difficult to turn it right.
2, the crab should be steamed and cooked thoroughly, and the raw crab should not be eaten.
Crabs 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. Some people don't get sick because they haven't washed the crabs thoroughly, or because they eat drunken crabs or pickled crabs raw, and they eat germs or parasites in the crabs. Steamed and cooked before eating, there will be no such problem.
3, crabs should be steamed and eaten now, not stored.
If you can't finish eating, the rest must be kept in a clean, cool and ventilated place. When eating, you must return to the pot and cook it thoroughly.
4. Don't chew crabs indiscriminately.
When eating crabs, you should pay attention to four things to remove after opening the lid: remove the crab stomach, that is, the triangular bone packet in the crab lid, eat the crab lid first, scoop out the middle crab stomach with a small spoon, and gently suck the crab yellow wrapped outside. Be careful, don't suck through the stomach of the crab with a triangular cone in the middle, and discard it if there is dirty sand in it; After eating the crab cover, it's the crab's turn. First, cut off the extra crab feet and mouth with scissors. Pick out a hexagonal piece in the middle of the crab with a spoon handle, which is the crab heart part that should be discarded. There is also a crab intestine, that is, a black line from the crab stomach to the crab navel; Crab gills, that is, two rows of soft things like eyebrows growing on crab abdomen, should be removed.
5, eat less, not too much.
Crab meat is cold, and people with spleen and stomach deficiency should pay special attention to avoid abdominal pain and diarrhea.
6. Try to eat less drunk crabs and raw crabs.
Although raw crabs are delicious, in fact, crabs may not only be accompanied by various viruses and bacteria, but also parasitic larvae of paragonimiasis. It is impossible to achieve thorough sterilization and disinfection only by soaking in yellow wine and white wine.
7. Don't eat with tea.
Don't drink tea while eating crabs and within 1 hour after eating crabs. Because boiling water will dilute gastric acid, tea will solidify some components of crab, which is not conducive to digestion and absorption, and may also cause abdominal pain and diarrhea.
8. Don't eat with persimmons.
Persimmons are ripe when crabs are fattened, so care should be taken not to eat these two things at the same time. Because tannic acid and other ingredients in persimmon will coagulate crab meat protein, the coagulated substance will ferment and rot in the intestine for a long time, causing vomiting, abdominal pain, diarrhea and other reactions, and may also cause lithiasis.
Note: (The four parts of the crab can't be eaten)
1, crab gills: the respiratory organ of the crab, which is very dirty inside. Remove the crab shell first after opening it.
2, crab intestines: there are crab droppings inside.
3, crab stomach: triangle bag hiding in crab yellow. Like crab intestines, there is also crab excrement.
4, crab heart: also known as crab hexagonal board. This thing is hard to find in crab roe, but it is hexagonal and looks conspicuous.
2, crab purchase instructions

Second weighing: for the sea crabs whose appearance meets the requirements by visual inspection, weigh their weight one by one, and the ones that feel heavy or heavy are called fat crabs.
