Both male and female crabs are actually delicious. The female crab has more crab roe, which is better to eat before October of the lunar calendar. After October, the crab roe will grow into crabs and be discharged, so the meat taste of the female crab is not as good as that of the male crab. At this time, the male crab has more crab paste than the female crab, which is sweet and tender, and the biggest feature is that it will not harden after cooking, and it tastes smooth and refreshing. In addition, the nutritional value of male crab and female crab is also different. The crab yolk of female crab contains cholesterol, while the male crab does not, so the male crab is more suitable for people with poor liver function.
Crab is rich in nutrition and contains many vitamins, among which vitamin A is higher than other terrestrial and aquatic animals, and vitamin B2 is 5-6 times higher than meat, 6- 10 times higher than fish and 2-3 times higher than eggs. The content of vitamin B 1 and phosphorus is 6- 10 times higher than that of common fish. The edible part of crab contains protein17.5g, fat 2.8g, phosphorus182mg, calcium126mg and iron 2.8mg per100g. Crab shell contains not only rich calcium, but also crab red and crab yellow.
The difference between male and female crabs is as follows:
1, male crab: We can distinguish the male crab by its biggest external feature "pointed navel", that is to say, the male crab has a thin triangular cover under his belly and sticks it tightly under his belly. The male crab grows slower than the female crab. By October, the fat of the male crab will gradually accumulate and grow into crab paste. When the crab shell is peeled off, you can see that the white sticky object is crab paste. After the male crab is cooked, the crab paste will become translucent. The more crab paste, the stronger the male crab.
2. Female crab: The biggest difference between the same female crab and the male crab is the belly, while the female crab's is the "ball navel", that is, there is a wide cover under the belly of the female crab, and there is a circle of hair on the edge of the cover, so the crab cover can be lifted with chopsticks. In September of the lunar calendar, the digestive glands and ovaries of the female crab grow into crab roe to prepare for the winter and the need of reproduction. When the crab shell is peeled off, a yellow sticky substance can be seen, which is raw crab roe. After being cooked, the crab roe will turn red, and the deeper the color, the stronger the crab is.
