Crab cryopreservation method:

Tie the crabs, wrap them in a damp towel, and put them in the refrigerator where fruits and vegetables are stored, and they can be stored for three to five days. If you want to leave it for a few more days, use a basin and put the crab in the basin.

Do not put water in the pot, and cover the top of the pot with wet aquatic plants or soft leaves. This not only ensures that the crab's living environment is neither dry nor wet, but also allows it to obtain sufficient oxygen.

In order to keep the crabs fresh, some people put the live crabs directly in the refrigerator and freeze them, thinking that in this way they can eat very fresh crabs. In fact, this practice is taboo, if you put it directly in the refrigerator to freeze, the crab meat will become very chai. When steaming, the crab roe is also easy to flow out, losing the deliciousness of the crab meat, and the gains outweigh the losses!

But don't use it this way.

Therefore, when keeping the crabs fresh, they should be put directly in the refrigerator, but it is a big taboo. Below I will share with you a little trick for preserving crabs, using my method to preserve, live crabs are very fresh for 5 days and will not die. You can eat delicious crab at any time!

Only a few towels are needed to preserve the crabs. Wash the tied crab a little and rinse the surface with clean water.

Then take a towel, wring the water after wetting, the water on the towel should not be too much, but not too dry, first spread a wet towel on the refrigerator, then tie the crabs one by one, and place them on top of the towel.

After setting it up, take out another towel, wet it and wring it again, then put this towel over the crab and cover the crab completely.

If you preserve the crab in this way, you can ensure the survival of the crab, even if it is left for 5 days, it is still fine. If you want to leave the crab for a long time, take the towel out again every day and re-wet it again to keep the crab moist so that the crab does not die.

But try not to leave the crab for so long, because if the crab does not eat for a few days, it will consume its own nutrients. The more time the crab is left out, the thinner the crab will be, and the worse the taste will be. You can only put it for 2 or 3 days in this way, and it shouldn't be too long, even if you put these crabs alive for a week, but the taste is not as good as when you just bought them.

This method is best used for only two or three days, and the fat crabs should be eaten quickly, and don't wait for them to become thinner before eating!

When eating every day, choose the crabs that are not energetic and energetic first, and you can continue to save them.

Note: Crabs can only be refrigerated and not frozen, freezing will freeze the crabs to death, and the meat will be frozen without any taste.

Write at the end: Usually eat seafood, the freshness of seafood is very important, stale crab shellfish not only have a bad flavor, but also easily cause poisoning. So if you can finish eating, try not to put it in the refrigerator to refrigerate.

Introduction to Crabs

Crabs belong to the class Mollusk, Decapod, and are crustaceans whose bodies are protected by a hard shell and breathe by gills. Taxonomicly, it is the same animal as shrimp, lobster, and hermit crab. The vast majority of species of crabs live in the sea or near the sea, but some inhabit freshwater or land.

Common crabs include pike crab, open-sea pike crab, blue crab and Chinese mitten crab.

The body of the crab is divided into cephalothorax and abdomen. The back of the cephalothorax is covered with a cephalothorax, and the shape varies from species to species. The frontal part has a pair of antennae, and the outer side is a stalked compound eye.

The mouthparts include 1 pair of large jaws, 2 pairs of small jaws, and 3 pairs of jaw feet. There are 5 pairs of breasts and feet on both sides of the cephalothorax. The abdomen is vestigial, flattened, and zigzags on the ventral surface of the cephalothorax.

A small group of crabs breed entirely in freshwater, and they mostly inhabit the rocks of mountain streams. There are also a few crabs, such as ground crabs, that can adapt to life on land, burrowing in damp mud holes, and migrating to the sea during the breeding season. The vast majority of crabs are omnivorous.

Some crabs are carnivorous, such as pike crabs, which can prey on fish, shrimp and molluscs.

It is better to steam and freeze.

If the crab at home cannot be eaten in time, it should be frozen in the refrigerator, then it is best to put it in the refrigerator after steaming, because the temperature of the refrigerator freezer is relatively low, and the raw crab is directly frozen, then it is easy to cause the crab meat to be frozen, and secondly, it will also lead to the reduction of the nutritional value and edible value of the crab.

Because crab is a food with a relatively high water content, low temperature will freeze the moisture in the crab meat, and the meat will be destroyed for a long time, so it is recommended that the crab is steamed and then frozen.

How to choose crabs:

1. Look at the fullness.

Although there are more crabs now, not all crabs are full, so when you buy crabs, you can choose the fleshy ones, you can open the crab navel, if there is yellow in it, then the meat is full, if it is white, then such crabs are not full enough.

2. Look at the color of Hezhou.

When choosing crabs, you need to look at the color, it is generally recommended to choose crabs with blue-black shells, shiny, full umbilicus, and white abdomen; If the crab shell is yellow, then it is not advisable to pick it.

3. Look at chelicerae.

When choosing crabs, you should choose a complete one, 1 pair of pincers and 8 feet of crabs can be missing, because the crab with chelicerae may be affected by the quality of the meat.

4. Look at vitality.

When selecting crabs, it is recommended to choose high vitality, turn the river crab over, belly to the sky, if the crab can quickly use the chelicerae to bounce back back, indicating strong vitality, can be preserved; If it can't be turned back, the vitality is poor, and the storage time can't be long.
