When will the three-door blue crabs come into the market
Generally speaking, the fattest time of the three-door blue crabs should be around the Mid-Autumn Festival, so every autumn, a large number of three-door blue crabs can be seen in the market, and the stalls selling the three-door blue crabs are also crowded.
But you should be careful when buying three blue crabs at this time, because this season is also the peak season for three blue crabs to mate and lay eggs, and the mated blue crabs are not so delicious. So relax when choosing three blue crabs.
In fact, we don't have to pay special attention to when the three-door blue crab is fattest. When we see it on the market in large quantities, we can know that it is the mature season of blue crabs. As for whether it is the fattest, it depends on personal selection skills.
How to identify the quality of Sanmen blue crabs
Sanmen County, Taizhou City, Zhejiang Province, is known as the "hometown of blue crabs" because of its delicious meat, many shells and large output. People who don't know about the three-door blue crab have some misunderstandings about it, so that they can't identify the quality of the three-door blue crab. Here we will lead you out of the misunderstanding and see how Sanmen blue crab can identify the quality.
1. The bigger the blue crab, the better. Many people think that since Sanmen blue crab is very fat, it should be very big, but it is not. The meat quality of many big blue crabs is not so tight. Generally, a good blue crab weighs two or three hundred grams.
2. Lift the blue crab and look at the jagged top of the crab shell in reverse light. If it is completely opaque, it means it is quite fat. Or it's not full.
3. The white or even transparent bottom of the blue crab indicates that the crab has just changed its shell. Because most of the energy is consumed when changing shells, there is generally not much meat. A dirty ass is often fatter.
4. If you don't eat the blue crabs at home immediately, you can't put them in the refrigerator. The optimum temperature is 8 to 18, and the blue crabs below 5 and above 39 die in a short time. If you want to keep it, you can put it in a cool and humid place and soak it in 18% physiological saline for 5 minutes every day. Generally, you can live for 3 to 5 days. You can live for 5 to 1 days at most.

Precautions
Three dead blue crabs can't be eaten.
When the blue crab is dying or dying, the oxygen acid in the crab will decompose to produce histamine, which is a toxic substance. With the longer the death time of the blue crab, more and more histamine will be accumulated in the crab, and the toxicity will become greater and greater.
some people say that I can't do it after high temperature heating? The answer is no! This toxin is difficult to be destroyed, even if it is heated at high temperature, it will not play much role, but will increase the burden on liver and kidney.
if you eat dead crabs by mistake and the toxins are not discharged in time, then poisoning will occur. Mild symptoms include vomiting, abdominal pain and diarrhea. Severe cases can be life-threatening.
Therefore, the dead three-door blue crabs can't be eaten, not only the dead blue crabs, but also the dead blue crabs. The dead crab toxin has begun to spread, and eating it is not good for your health.
How to preserve the three-door blue crab
For the three-door blue crab, I believe the most sad thing is how to preserve it. This kind of thing is too difficult to make. Choose fresh food, not dead. I accidentally bought too much, but I couldn't watch it die. What should I do?
actually, the method is very simple. When it is still alive, tie its feet and throw it in the refrigerator. Remember that the temperature of the refrigerator should be controlled at 5-8 degrees, so that it can survive for about three days.
If you want it to live longer, find a plastic basin 3-5 cm high, put it in (don't fold it), then add water to half of its body (don't drown it) and put it in the shade, which will last for about five days.
The third method is to put your bathtub out, put it in, and then inject water directly under the crab's body, so that the blue crab can just breathe on the water when standing. Put some small fish and shrimp according to the storage time and quantity. This can last for 7-1 days.
during the fresh-keeping period, remember to check the living conditions of some crabs from time to time. If half-dead or dead crabs are found, take them out immediately so as not to affect the quality of other crabs.
