However, you should be careful when buying Sanmen blue crabs at this time, because this season is also the peak period of mating and spawning of Sanmen blue crabs, and the mated blue crabs are relatively not so good in taste. Therefore, you should be careful when choosing three blue crabs.
In fact, we don't need to pay special attention to when Sanmen blue crab is the fattest. When we see it on the market in large quantities, we can know that this is the mature season of blue crabs. As for whether it is the fattest, it depends on individual selection skills.
How to identify the quality of three-door blue crabs Sanmen is a county in Taizhou, Zhejiang Province. The blue crabs produced here are rich in meat, thin in shell and large in output. It is a famous "hometown of blue crabs". However, people who don't know about the three-door blue crab have some misunderstandings about it, so that they can't identify the good or bad of the three-door blue crab. Let's lead you out of the misunderstanding and see how the three-door blue crab can identify the good or bad.
1, the bigger the crab, the better. Many people think that since Sanmen blue crab is very fat, it should be very big, but it is not. On the contrary, many large blue crabs are not so firm in meat quality. Generally, good blue crabs weigh 200-300 grams.
2. Lift the blue crab and look at the serrated top of the crab shell in the backlight. If it is completely opaque, it means it is quite fat. On the contrary, it is not full.
3. The white or even transparent bottom of the blue crab means that the crab has just changed its shell. Because it consumes most of the energy when changing its shell, it usually has little meat. Dirty bottoms tend to be full of meat.
4. If you don't eat it immediately when you buy it home, you can't put it in the refrigerator. The most suitable temperature is 8 to 18℃, and the blue crab will die in a short time below 5℃ and above 39℃. If you want to preserve it, you can put it in a cool and humid place and soak it in 18‰ salt water for 5 minutes every day. Generally, it can live for 3 to 5 days. The longest life span is 5 to 10 days.

matters need attention
Dead three-door blue crabs can't be eaten.
When the blue crab is dying or dead, the oxygen acid in the crab will decompose to produce histamine, which is a toxic substance. As the blue crab dies longer and longer, the histamine accumulated in the crab will be more and more, and the toxicity will be greater.
Some people say that I can't do it after high temperature heating? The answer is no! This kind of toxin is difficult to be destroyed, even high temperature heating will not play much role, but will increase the burden on the liver and kidney.
If you eat dead blue crabs by mistake, and the toxins are not discharged in time, then poisoning will occur. Mildly manifested as vomiting, abdominal pain, diarrhea and other symptoms, and may be life-threatening in severe cases.
Therefore, the dead three-door blue crabs are inedible, not only the dead blue crabs are inedible, but also the dying blue crabs are inedible. The dying blue crab toxin has begun to spread, and eating it is also bad for your health.
How to preserve the Three-door Blue Crab For the Three-door Blue Crab, I believe that what makes everyone extremely sad is how to preserve it. This kind of thing is really difficult. You must choose to eat it alive, but you can't eat it dead. What should I do if I accidentally buy too much and can't watch it die?
In fact, the method is very simple. When it is still alive, just tie its feet and throw it into the freezer of the refrigerator. Remember that the temperature of the freezer should be controlled at 5-8 degrees, so that it can survive for about three days.
If you want to make it live longer, find a plastic basin 30-50 cm high, put it in (don't stack it), then add water to half of its body (don't drown it) and put it in the shade, so it can be stored for about five days.
The third method is to give up your bathtub, put it in, and then inject water that has just passed the crab's body, subject to the blue crab standing just enough to breathe on the water. Put some small fish and shrimp according to the storage time and quantity. This can be stored for 7- 10 days.
During the storage period, remember to check the survival status of some crabs from time to time, and take them out immediately if you find that they are half dead or dead, so as not to affect the quality of other crabs.
