In China culture, crab is also a very popular food and one of the important economic aquatic products in the world. Whether it is steamed, braised or fried, it is very delicious. At the same time, crabs play an active role in the restoration of water environment and the maintenance of ecological balance, and are an indispensable part of marine ecosystem.

Although crabs are good, they can't be eaten overnight. Crabs are rich in protein, which is easy to deteriorate overnight and can't be eaten. Don't eat crabs if they have an odor, sticky surface or obvious discoloration. Fresh crabs are best eaten on the day of purchase or within 24 hours after purchase to ensure the best taste and quality.

Cleaning method of crab

When washing crabs, you should not only prepare clean water, but also prepare an abandoned toothbrush. Put the prepared clean water directly into the deep basin, and then put the crabs that need to be cleaned into it. Don't worry about crabs running around, because crabs keep moving in the water, so the dirt on their surfaces will be washed away. If they run out of the basin, they can be caught and thrown back.

After the crab has been soaked in the basin for three or four hours, grab its sides by hand, then brush its back, abdomen and mouth with a clean brush, and then clean the sides of the crab, its feet and the roots of pliers with a brush. Only in this way can all the dirt on its surface be removed. In addition, grab his pliers by hand, then brush his middle with a toothbrush. Finally, cover him with a clean brush to clean up all the excrement inside, and then rinse it with clear water.
