After the male crab is opened, the white paste substance inside is actually crab paste, which is the accessory gonad and secretion of the crab. After the male crab matures, its accessory gonad is extremely developed, which occupies most of the reproductive system, and even lifts the crab shell at this time. The natural state of crab paste is bluish-white translucent jelly-like liquid, and it is translucent after steaming. Sticky, gelatinous, crab paste is rich in protein, fat and various mineral components, and its nutritional value is very high.

What is the yellow in the middle of the male crab? Hepatopancreas.

There is no crab yellow in the male crab. If there is a yellow substance in the male crab after it is opened, it is probably the hepatopancreas of the male crab, which is next to the testis of the male crab, and only the hepatopancreas in the crab that is not fully mature is yellow, and it will be thin and tastes very bitter. When the crab matures, the color of its liver and pancreas will change, the texture will be shaped, and it will taste better.

3 Eat male crabs in a few months and female crabs in a few months. Eat female crabs in September and male crabs in October.

There has always been a saying among the people that "the navel in September is pointed in October", which actually refers to the time to eat crabs. The navel is the female crab, while the pointed navel is the male crab, so September in the lunar calendar is the best time to eat the female crab. At this time, the female crab yellow is full of meat, and it tastes very full and the meat is fresh and sweet. By October of the lunar calendar, the male crab is very big, and the crab paste and crab meat are very fat.

4 What's wrong with the yellow of the female crab? The crab's maturity is not normal. The crab's yellow taste is very fresh and delicious, but if the crab's yellow tastes bitter, it is probably because the crab's maturity is not enough, so the taste will be greatly discounted.

The crab roe eaten with viscera is very close to the viscera. If the viscera is not removed when eating crab roe, the overall taste may be bitter, because the viscera contains crab excrement.

Crabs are stale. In addition, if you eat stale crabs, the taste of crab yellow may be bitter, and it will have a bad impact on your health after eating.
