Can you eat purple crabs?

We all know that crabs generally look red, especially those spicy crabs, which look spicy and red. However, the storage time of fresh crabs is very short. If crabs are kept in basins of water, they can be kept for a long time as long as they are alive. But if they die, they will easily rot if not kept in the refrigerator. So, can crabs still be eaten if they turn purple?

When a crab is dying or dead, the histamine in its body breaks down into histamine. Histamine is a toxic substance. As the time of death increases, more and more histamine accumulates in the crab body, and the toxic gas becomes stronger and stronger. Even if the crab is cooked, this toxin is not easily destroyed.

To buy fresh river crabs, you should do "five things" when choosing crabs: one is the color; two is the individual; three is the belly button; four is the crab hair; and five is the movement. The crab should have a green back and a white belly, golden claws and yellow hair. The crab should be large, strong and healthy. The belly button should protrude outwards. The crab legs should be covered with dense hairs. The crab should be agile and active. Only products that meet these 5 criteria are worth buying.
