The difference between male crab and female crab who has crab roe, and whether the crab roe is male

Crab roe is unique to female crabs, and the kind that male crabs have is called crab paste. If you want to eat crab roe, then you have to buy a female crab, and the biggest difference between male crabs and female crabs is that on their navel, the navel of male crabs is pointed, and the belly is covered with a thin triangle, while the female crab is a round navel, and the cover under the belly is much wider than that of male crabs. If you want to buy a female crab with a lot of crab roe, you must choose a large one, because the large female crab grows for a long time, and the crab roe accumulated in the body is more abundant.

In addition, the back of a good crab with a lot of crab roe is blue and hard, and the belly is full and heavy.

Precautions for eating crabs:

1. Don't eat dead crabs: Crabs contain a lot of histidine, and after death, bacteria multiply in the crab's body, which will make histidine form histamine, a substance harmful to the human body, and the longer the crab dies, the more histamine content in the body, if people eat dead crabs, they will have allergies or poisoning, so dead crabs must not be eaten.

2. Don't eat cooked crabs that have been left for a long time: Crabs should not be eaten that have been dead, but if they are cooked crabs that have been left for a long time, they should not be eaten. Because the protein content in crabs is very high, it is easy to spoil and deteriorate, and it is easy to be contaminated by bacteria at room temperature, so crabs must be steamed and eaten, and it is best not to eat crabs that have been stored for too long.

3. Don't eat raw crabs: Some people salted crabs, soaked them in vinegar and wine, and it is easy to inhale the lung flukes in raw crabs into their bodies. These parasites are in the human body, causing people to cough, cough up blood, etc., and also invade other organs such as the brain.

Therefore, the crabs you buy must be steamed before eating.

4. Don't eat with persimmons: persimmons, strong tea and other foods contain high tannin content, if eaten with crabs, the human body will have nausea, vomiting, diarrhea, abdominal pain and other phenomena.

Is the crab roe a male or female crab.

Of course, it's the female crab, and the male crab is crab paste. The belly of the female crab is round, and the belly of the male crab is pointed like a yellow crane tower. Now should be the time to eat female crabs, the crab roe is plump, and it is not yet time to eat male crabs, and male crabs will not be fat until around the 11th National Day.

Crab roe, the ovaries and digestive glands in the crab's body, are orange and delicious. Crab roe is not a crab egg, although the composition is basically the same as crab eggs, but there is an essential difference between the two. Crab roe does contain egg cells that have not been excreted from the body, but there are other crab organs, glands, tissue fluids and other substances, which are not just crab eggs.

When the roe grows in size and turns bright orange, the gonads of the female crab have matured, and the eggs are produced and excreted from the body, and the egg cells left in the gonads in the body are still part of the crab roe. Crab roe is rich in protein, phospholipids and other nutrients, which is rich in nutrients, but also contains high levels of oil and cholesterol.

How to distinguish a male and female crab.

It seems that the appearance of hairy crabs is basically the same. You can't see it at all from the shell. A simple way can be distinguished, look at the belly of the hairy crab can be distinguished, and to make a very vivid analogy, the male crab wears a thong, and the female crab is wrapped in diapers.

That is to say, the male crab has a long shell on the abdomen, which is pointed, and the female crab is round. Another way is to open the shell, if there is a yellow one, it is a crab roe, it must be a female, if it is white, it is a crab paste, it must be a male. Male crabs have more meat than female crabs.

How to choose a crab with good crab roe.

1. Look at the color.

First, the crab shell should be green, the crab belly should be white, and it should not be black; The second is that the tail of the crab should be red or yellow, and it should be raised high (the shell part of the crab should be separated from the root of the crab navel and have a feeling of fullness), which proves that the crab roe (paste) is very full.

2. Pinch soft and hard.

Pinch the crab's leg with your hand, if it feels very soft, it means that the crab is very empty, there is no meat, and the crab paste and crab roe cannot be very full. If the crab legs are very hard, it means that this is a "robust" crab, and combined with the above 3 points, you will definitely be able to pick a good crab with yellow and fat cream.

Female crabs have crab roe, and crab roe is unique to female crabs, and male crabs do not have crab roe. The differences between male and female crabs are: different abdomen, different legs, and different sizes.

Crab roe is unique to female crabs. Some people want hairy crab roe more, in the purchase of male crab or female crab difficulty, in fact, to eat crab roe, is necessary to buy female crab, male crab is not crab roe, male crab and female crab crab roe corresponding to the part is white crab paste.

How to distinguish between male and female crabs.

The male and female who distinguish between the male and female of the crab are mainly observed in appearance by observing the navel of the crab. The female crab has a round umbilicus and a wide lid under the belly, while the male crab has a pointed umbilicus and a thin triangular lid under the belly.

What kind of female crab crab has more crab roe.

If you want to buy crabs with more crab roe, there is no doubt that you must first choose the large one, because the formation of crab roe in the body of the female crab accumulates with the age of the female crab, and the large crab grows longer and accumulates more crab roe. Generally speaking, a 2 to 3-year-old female crab is considered to have more crab roe;

Secondly, hold the crab in your hand, the heavy feel is the fat and strong good crab, and the light feel is mostly the shriveled and less meat of the bad crab. A good crab with a lot of crab roe has a cyan and hard back and a full and heavy belly. You can also take a closer look at the crab legs, which are hard to pinch and have the fattest crabs.

I think. Of course, the one with more crab roe should be the female crab, because whether it is fish, crab or shrimp, the food of seafood products is yellow in the female, and the male only has oil and no yellow. Therefore, the female crab with more crab roe is the female crab, otherwise many people will buy the female crab when they buy crabs, because the female crabs are yellow at this time, and they are sold in supermarkets or markets.

The first unloaders are all sold by the mother, and the male is sold. Slightly cheaper than the female one. So I like to eat crab roe or shrimp, shrimp roe.

of buyers will pick the mother's to buy. I think these seafood things are really delicious when they are yellow.

There are three main differences:1. Different sizes:

Male crabs are larger than female crabs.

2. The navel is different:

The navel of the male crab is triangular.

The female crab has a round belly.

3. The fluff on the legs is different

The male crab legs have a lot of fluff, while the female crab legs are smooth.

Tips for picking fresh crabs:

1. The degree of connection between the limb and the body. The fresh crab foot is closely connected with the body, and when the crab body is lifted, the foot does not slack and sag. Stale crabs will obviously show relaxation at the rotational place where the limbs and body meet, and the limbs (feet) can be seen to hang down when the crab body is lifted by hand.

2. Look at the "stomach print" above the abdominal button. Crabs mostly feed on humus, and after a period of death, the stomach contents of stale crabs will decay and black marks will appear above the umbilicus on the ventral surface of the crab body.

Crab roe is unique to female crabs, male crabs do not have crab roe, and the part of male crabs that corresponds to female crab roe is white crab paste.

Crab roe is not the egg of a crab, but it is indeed the ovaries and digestive glands in the body of the crab, and it also contains egg cells that are not excreted from the body. After the crab is steamed, the shell is opened, and the crab roe is orange and brightly colored, which indicates that the gonads of the mother crab have matured.

Selection of multi-crab yellow crab:

1. Select female crabs: The male and female who distinguish crabs are mainly to observe the navel of the crab in appearance. The female crab has a round umbilicus and a wide lid under the belly, while the male crab has a pointed umbilicus and a thin triangular lid under the belly.

3. Weigh the weight: hold the crab in your hand, the heavy feel is the fat and strong good crab, and the light feeling is mostly the shriveled and less meat of the inferior crab.

Of course, there are many female crab yellows. Female crabs have the function of reproducing offspring, so there are many female crab yorks.
