If the crab is tied and taken apart, some people will not tie it again, and the crab will easily get caught in their hands, so you can prepare a useless old, clean small toothbrush, and then gently scrub the crab's back and abdomen. At the same time, when washing, you can remove the rope or straw that tied the crab and move it, brush it clean and return to its original position, so that it can be cleaned.
2. Soak in salt water
The crabs bought have been tied with ropes, so it is not easy to clean them. You can prepare some salt water, and then soak the crabs in the salt water. The salt water has the function of sterilization and disinfection, and after soaking, some dirt on the surface of the crabs will be soaked down, and then washed repeatedly with clear water, especially for places tied with ropes or straws, or washed clean with water.
3. Use baking soda
Baking soda powder can not only make food fluffy, but also has the function of adsorbing dirt, which can attach and take away the dirt on some food. So you can prepare some baking soda powder, then sprinkle it on the surface of the crab, let it stand for about half an hour, and then rinse it constantly with clear water. You can brush it with a small brush, so that the crab can be washed very clean.
Precautions for cleaning crabs
1, observation vitality: fresh crabs are full of vitality and strong limbs. When shopping, you can turn the crab upside down. If it can quickly turn over and climb up, it shows that it has strong vitality. At the same time, observe the abdominal feet of crabs. The abdominal feet of crabs with strong vitality are tight and will contract strongly when touched.
2. Color: Fresh crabs have bright color, smooth shell surface and no shedding. The abdomen is full, white or yellowish, and there is no peculiar smell. Pay attention to avoid buying crabs with dim colors and dirt on their shells.
3. Distinguish between male and female: The male crab has a narrower abdomen and the female crab has a wider abdomen. Under normal circumstances, male crabs are delicious, while female crabs are slightly inferior in taste. When choosing, you can choose according to your personal taste and needs.
4, check the internal organs: turn the crab's stomach over and observe its internal organs. The viscera of fresh crabs are bright in color and have no peculiar smell. If the internal organs are black or have foreign bodies, it means that crabs are no longer fresh.
