Many people like to eat crabs, especially the crab roe of female crabs, but there are many times when the crab roe of female crabs is black, so what is going on? In this article, I will briefly share this knowledge:

Some crab friends eat a black thing when eating crab roe, which is crab stomach, which also contains some crab food residues, although the crab stomach is inedible, but it does not affect the consumption of crab roe. There is also the crab with the growth and development, every once in a while to molt the shell, when molting, between the hard shell and the crab roe will form a layer of black membranous substance, this inner membrane will be covered on the crab roe after steaming, giving people an illusion that the crab roe turns black, in fact, this black crab roe can also be eaten.

There are also some people who eat female crabs to have the phenomenon of crab roe turning black, which is normal, because this black is the fertilized egg of the crab, that is, the crab roe to be laid. However, it is edible, and when it is steamed, it will disappear after a little longer. Produced by female crabs after mating, the boundary between yellow and black is obvious.

Crab roe is the ovaries and digestive glands in the body, when the crab roe becomes larger and bright orange, it means that the gonads of the mother crab have matured, and it is the crab eggs that are produced and discharged from the body, and the egg cells left in the gonads in the body are still part of the crab roe. Crab roe is not a crab egg, but its composition is basically the same as that of crab eggs.

There is also a situation to pay attention to, that is, hairy crabs belong to scavengers, their food is complex and diverse, most hairy crabs have toxins and parasites in their bodies, therefore, crabs will be eroded by toxins and parasites within ten minutes after death, this kind of crab is steamed again, there will be a phenomenon of crab roe bruising, not suitable for consumption.

Then there is the pollution of the environment, the breeding of hairy crabs has high requirements for water, many farmers for the sake of profit, the hairy crabs are raised in ponds, rice fields and other places with more silt, the crabs themselves are seriously polluted, crab roe is one of the organs and secretory glands in the crab's body, it will also be slightly infected, the color of crab roe turns yellow and black, this crab is not suitable for eating.
