What is the white liquid that comes out of steamed crabs?

The white liquid that comes out of steamed crabs is the body fluid of the crab, also called tissue fluid. The crab body fluid contains a large amount of protein, inorganic salts and other substances. After being heated at high temperature, these components denature and coagulate, eventually forming a white liquid. Generally, it is harmless and can be eaten with confidence.

When heated, protein will coagulate into white flocs. When the crab is heated, the body fluid will expand and overflow, and the flocs will be discharged together and stick to the surface of the crab shell.

Before steaming crabs, you can soak them in cold water for a while to soak out the mud and impurities in the crab's body.

Crabs have a strong fishy smell. When steaming them, you can apply some cooking wine or add a few slices of ginger to remove the fishy smell.

What are the storage methods of crabs?

It is recommended to store crabs in refrigerators, plastic basins, plastic wrap, etc. Fresh live crabs can be stored in the refrigerator's cold storage compartment. Adjust the temperature of the refrigerator compartment to between 5℃-10℃ and cover the crabs with a towel for short-term storage. Cooked crabs can be stored in plastic wrap. Cover the surface of the crabs with plastic wrap evenly and store them in the refrigerator's cold storage compartment.

Common crabs include swimming crabs, deep-sea swimming crabs, blue crabs and Chinese mitten crabs (river crabs, hairy crabs, clearwater crabs), etc.

The crab's body is divided into the cephalothorax and abdomen. The back of the cephalothorax is covered with a cephalothorax, the shape of which varies from species to species.

Crabs belong to the class Molluscs, order Decapoda, and are crustaceans. Their bodies are protected by hard shells and they breathe through gills.
