Is it okay to put live river crabs in the refrigerator, and can live river crabs be frozen directly

1. Live crabs can be refrigerated in the refrigerator for preservation, we need to use a rope to pincer live crabs before refrigerating them.

Tie up its feet to reduce its activity, reduce its physical exertion, and put it in the refrigerator and cover it with a wet towel, so that the crabs are in a well-hydrated environment, and they are not easy to die.

2. This method can preserve the crab for about three days, and when we eat refrigerated live crabs, we can give priority to those with low vitality. Touching the eyes of crabs with your fingers, those that are slower to respond to touch are less energetic.

3. In addition to refrigerator refrigeration, you can also put it directly into the basin and spray them with water regularly, pay attention to keep a certain gap between the crabs and crabs, and use this method to keep the crabs alive for three to five days.

OK. If the live crab can be eaten in a short period of time, it is recommended to put it in the refrigerator to ensure that the taste and taste of the crab meat will not change, but if you need to keep the live crab for a long time, you need to put it in the refrigerator to freeze, with the help of the environment of more than ten degrees below zero, in a relatively no bacterial breeding condition, the live crab can be stored for a long time, but after thawing, the crab meat is relatively soft and rotten, and the taste is no longer sweet.

Not recommended. It is not recommended to put live crabs directly in the freezer to freeze them. The survival temperature of crabs is 4-30 degrees Celsius, and the temperature of the freezer is generally below zero degrees Celsius, below 4 degrees Celsius crabs can not survive, live crabs will die if they are directly frozen, and dead crabs are not recommended to eat.

In addition, the water in the body and meat of frozen crabs will crystallize due to low temperature, which will destroy the taste of the meat, and most of its nutrients will be lost, and at the same time, the umami taste of crabs will be lost. It is best to put the crab in the refrigerated area, which can not only preserve the freshness of the crab, but also ensure the taste of the crab.

This is not recommended. Fresh crabs can be directly placed in the freezer of the refrigerator to freeze, but this practice feels too rough, and crab is a kind of aquatic product, the most important thing when we eat is to eat the umami of seafood, if you put it in the freezer and then cook, then the taste will be greatly reduced, and it will also make the meat fat, and the fishy smell of the crab may be more recognizable, so it is better not to do this, it is recommended to keep the live crab for a short time Refrigeration, It is best to store it at room temperature. But if you want to store crabs for a long time, then you can only put the crabs in the freezer of the refrigerator, in this case, it is best not to exceed three months, but you must pay attention to the crab must be frozen when it is alive, if the crab has died, then it is recommended that you do not freeze and store it, because it is easy to produce histamine after the crab dies, this toxic substance, if we take the crab out to eat, it is very likely that there will be food poisoning, Causes abdominal pain, diarrhea and other symptoms.

2. Can live crabs be eaten if they are directly frozen?

I can eat it. After the live crab is frozen, it needs to be stored at -18, this method can retain the nutrition and quality of the seafood, and is suitable for long-distance and long-term preservation, but the meat quality cured at low temperature is eaten after being processed at room temperature, and the crab meat will become soft and glutinous and powdery, which will reduce the taste when eating, but it does not affect the health and can be eaten with confidence.

3. How long can live crabs be kept directly frozen?

It is best to eat it in 1 month. Live crabs are stored in the freezer in a harsh low temperature environment, and there is almost no breeding of bacteria and other microorganisms, so it can be stored for a long time, but with the extension of the storage time, the taste and nutrition of the crab will also be greatly reduced, so it is recommended to eat it within 1 month. It is recommended to cook and freeze the crab, so that it can be kept for a long time and the taste remains unchanged, just put the crab into the brine and cook, and then freeze, this method completely retains the elasticity and nutrition of the seafood meat, can be transported for a long time, and also shortens the cooking time, which is a more common and stable freezing method.

No. When live river crabs are put into the freezing area, the temperature is too low, which will speed up the death of river crabs; And due to the reason of living water quality, it contains many bacteria and other microorganisms in its body, and it is easy to cause more bacteria to breed and deteriorate directly in the freezing area, which will also affect the meat quality, so it is recommended to cook the river crab and then put it in the freezing area for preservation.

Further information: River crab (Latin scientific name: eriocheir-sinensis-milne-edwards, alias:

Hairy crab), a genus of arthropods in the family Mitten crab in the family Square Crab. River crabs often burrow on the mud banks of rivers, rivers and lakes and marshes, and are active at night.

The cephalothorax formed by the combination of head and thorax is square and hard, with a pair of eyes at the front of the body and two pairs of very sharp crab teeth on the sides; The surface of the chelicerae is covered with villi, after the chelicerae there are 4 pairs of feet, the sides are flattened and long, the abdominal limbs are vestigial, the abdomen of the female is round, and the abdomen of the male is triangular. It feeds on fish, shrimp, carcasses and grains, and often migrates to the estuaries of the sea every autumn to spawn.

Direct freezing is generally not recommended.

Because of the water quality of the live river crab, the body contains many bacteria and other microorganisms, and it is easy to cause more bacteria to breed directly in the frozen area, and the deterioration will also affect the meat quality.

Why is it not recommended to cryopreserve hairy crabs?

Although it is said that fresh crabs can be directly placed in the freezer of the refrigerator to freeze, but this practice feels too rough, and crab is a kind of aquatic product, the most important thing when we eat is to eat the umami of seafood, if you put it in the freezer and then cook, then the taste will be greatly reduced, and it will also make the meat fat, and the fishy smell of the crab that may be more recognized will be heavier, so it will lose the umami of the seafood, and it is best not to do this.

What methods are feasible to preserve hairy crabs?

In daily life, if you buy a lot of crabs at one time and can't eat them all, then it is okay to store the crabs in the refrigerator for 4 to 5 days, we only need to buy the crabs and do not need to clean the crabs, nor do we need to untie the ropes of the crabs, directly put the crabs in the refrigerator compartment, and then cover the back of the crab with a wet towel, under the temperature of the refrigerator, the crab will be in a state similar to dormancy, and in this case, It can last for days without dying. When we take the crab out and cook it again, we can still eat the crab very delicious.

What should I do if I have to store it for a long time?

If you want to store crabs for a long time, then there is no way to put the crabs in the freezer of the refrigerator, in this case, it is best not to exceed three months, but you must pay attention to it, it must be frozen when the crab is alive, if the crab has died, then it is recommended that you do not freeze and store it, because it is easy to produce histamine after the crab dies, and if we take the crab out to eat, it is very likely that there will be food poisoning. Causes abdominal pain, diarrhea and other symptoms.
