The price of seafood such as crabs is generally quite expensive, but crabs are rich in nutrients, including a lot of high protein. However, when eating crabs, you need to be careful about what you eat. You cannot eat crabs with sweet potatoes, pumpkins, honey, etc., otherwise it will cause diarrhea. It is best to soak crabs in salt water before cooking. How long should you soak crabs in salt water?

First, how long should you soak crabs in salt water? Soak them in light salt water. After buying the crabs home, first rinse off the dirt on the surface of the crabs, and then soak them in light salt water for a period of time. The concentration of the salt water should be such that it tastes slightly salty. The purpose of soaking crabs in light salt water is to make them vomit out the dirt in their stomachs, so the water should be changed several times during the soaking period until the water vomited by the crabs becomes clear.

Second, how to wash frozen crabs? Take out a toothbrush, grab both sides of the crab, and use the toothbrush to vigorously clean the back, abdomen and mouth. Then clean the sides of the crab and the bases of its feet and claws. Open the abdominal lid and squeeze out the excrement from the inside to the outside in the middle. Frozen crabs are not as delicious as fresh ones. After freezing, the water in the crab meat will crystallize, expand and puncture the cell walls. After thawing, the moisture will be lost when heated, and the crab meat will feel noticeably tougher. Therefore, it is best not to freeze crabs. Try to eat them all at once. If you cannot finish them, steam them and refrigerate them at 0-4 degrees and eat them as soon as possible.

Crabs live in water and like to eat dead fish, dead shrimps and other rotten animal carcasses in the water. After being caught, crabs often try to break free, which causes an increase in lactic acid in the body. This will cause the bacteria in the crab's body to multiply rapidly and spread into the crab meat after the crab dies. Then, the crab will be infected with certain bacteria. Especially river crabs, most of which grow in polluted rivers and ponds, and there are a large number of pathogens inside and outside the crabs' bodies. Live crabs can excrete bacteria through metabolism in their bodies; once a crab dies, the bacteria in its body will multiply and decompose the crab meat. Some bacteria also produce toxins. If people eat such crabs, they will suffer from food poisoning. Common symptoms include nausea, vomiting, abdominal pain, and diarrhea. In severe cases, dehydration, electrolyte imbalance, convulsions, and even shock, coma, and sepsis may occur.
