What causes crabs to be black and paste?

The black crab paste is a sign of sexual maturity of male crabs. It is mainly the black crab paste inside the crab, which is composed of the male crab organs and semen in the seminal vesicles, and has certain nutritional value.

Crabs are a common seafood and are relatively cold in nature. Eating them frequently may cause the stomach and intestines to become weaker, but they are also rich in nutrients, such as protein and fat, and contain minerals needed by the human body. Eating them in small amounts can help supplement nutrition. The crab roe of male crabs is generally bluish-white, but sometimes it is also black. Most of them are translucent jelly-like and feel very sticky when touched. If it is an immature male crab, insufficient steaming time may cause the crab roe to turn black. It usually does not have a significant effect on the taste, but it is necessary to judge whether it tastes bitter.

There are male and female crabs, and there may be some differences when eating them. Crabs can be steamed. The steaming time needs to be controlled well, and you also need to observe whether the crabs are fresh. When buying crabs, try not to choose dead ones, otherwise it will have a significant impact on the quality of the crabs, and you may also experience physical discomfort symptoms, and some bacteria may grow.
