There are a large number of microorganisms in aquatic products, such as Vibrio parahaemolyticus and Vibrio cholerae, which have a high proportion, and even carry a variety of parasites. Must be effectively heated and sterilized to ensure safety.
Live crabs should be steamed and cooked thoroughly, and live crabs can excrete bacteria from their bodies through metabolism. Once the crab dies, the bacteria in the body will multiply and decompose the crab meat, and some bacteria will also produce toxins, causing food poisoning.
Matters needing attention
1. Choosing crabs is actually very simple. Look at the position of the crab's navel. Yellow and red crabs are good crabs. Generally speaking, it can't be wrong, just like the picture 1 in the menu.
2. Again, crabs must be bought alive.
The steaming time depends on the size of the crab. Generally, the parasitic bacteria in crabs can be killed by steaming 12- 15 minutes after boiling, but if the crabs are more than four and a half minutes, it needs to be steamed for three or four minutes. It is necessary to ensure the delicacy of crabs and the cleanliness and hygiene of crabs.
