Put the live fish in the refrigerator and freeze it into ice cubes and thaw it, can the fish still l

Put the live fish in the refrigerator and freeze it into ice cubes before thawing, of course, the fish can't live, so when you usually buy seafood, you must pay attention to the freshness of it, buy high-quality seafood to eat, so as to meet the requirements of a more hygienic and safe diet.

No. Put the live fish in the refrigerator and freeze it into ice cubes and thaw it, and the fish will not be alive. Because the body temperature of the frozen fish drops sharply, it is lower than the normal metabolic body temperature range, which affects the normal progress of life activities and leads to death. ”

This one can't live. There have been experiments on this, but it was based on a freeze. And the refrigerator freezes too slowly. In the process of freezing. The cells of the fish have been damaged. At this point, he was dead.

Personally, I don't think the fish will come back alive because it has been frozen to death inside the freezer. Instead of fainting from the hole, if you faint for a short time, the fish can be resurrected after encountering water, but it cannot be resurrected if it has frozen to death.

If it won't live, it will freeze to death, put the live fish in the refrigerator and freeze it into ice cubes and thaw it. It won't survive.

Put the live fish in the refrigerator and freeze it into ice cubes before thawing, the fish cannot be resurrected, it has frozen to death.

If you put the live fish in the refrigerator and freeze it, and then thaw it after freezing into ice flowers, I don't think it will be possible for the hospital to live again. Because in this case, it's not like being in the sea, where there is oxygen.

The possibility of survival is very small, and the damage to the somatic cells of the fish is relatively large in the process of freezing and thawing.

Fishes are the oldest vertebrates. They inhabit almost every aquatic environment on Earth – freshwater lakes, rivers to saltwater seas and oceans.

Fish are mainly divided into: tropical fish, temperate fish and cold ribbon fish.

Aquatic fish are divided into: freshwater fish and saltwater fish.

Fish have good hearing. Scientists have found that although many fish do not have long ears on the outside, they have specially designed sound receivers that transmit sound waves to the fluid-filled tubular structure in the inner ear.

The efficacy of fish: autumn and winter are a good time for the weak to take supplements, and fish is a good aquatic food for tonic, which is not only delicious, but also has high nutritional value.

Its protein content is twice that of pork, and it is a high-quality protein with a high absorption rate in the human body. Fish is rich in thiamine, riboflavin, niacin, vitamin D and a certain amount of calcium, phosphorus, iron and other minerals. Although the fat content of fish meat is low, the fatty acids in it have been proven to lower blood sugar, protect the heart and prevent cancer.

Vitamin D, calcium, and phosphorus in fish are effective in preventing osteoporosis.

The fat of fish contains unsaturated fatty acids, which have anti-atherosclerotic effects, so it is beneficial for the prevention and treatment of cardiovascular and cerebrovascular diseases, enhancing memory, protecting eyesight, and eliminating inflammation.

However, the more fish you eat, the better, because the fatty acids of fish contain a large amount of eicosapentaenoic acid, which can inhibit the coagulation of platelets.

No, because the internal organs of the fish are frozen out. But hard-shelled animals such as crabs can, because they have a hard shell that doesn't freeze their internal organs.

Ordinary methods will not work! Because the cells of fish are ruptured! The fish naturally died!

But now there is a new way to freeze the fish with a special freezing liquid, so that the fish cells will not burst! Fish have the possibility of coming back alive, but not all fish can, and the fish that hibernate have the best chance of resurrection! You can take a look at the program of ** Channel 10, there is an introduction in one issue

It depends on what kind of fish it is, most of the fish will definitely not survive, for example, we have a local species called the old man's fish here, which will not die if frozen on the ice for a long time, but other fish can't.

In nature, you can see what kind of fish it is. For example, in fresh water, there is a fish called Manchu (old man's fish) in the river water. In winter, in the river, the water is completely frozen into ice, and by the beginning of spring, the river melts. And it came alive.

Hehe, dear, you're so talented......Freeze the live fish in the freezer and it will be reincarnated You have done a good deed!!

The temperature of the refrigerator is only a few degrees below zero. And the fish slowly cool down when they enter it. So the tissues in the body will be frozen.

If the temperature can reach about minus 60 degrees. And it's instantaneous. I think it should be able to survive.

Because the use of low-temperature rapid micro-freezing technology to freeze fish can not destroy its cells, within seven days after freezing, as long as it is re-thawed in water, the frozen fish can be "resurrected" after more than ten minutes. However, the main purpose of low-temperature rapid micro-freezing technology is to preserve the freshness of fruits and meats, and does not pursue the eyeball effect of "resurrecting" the fish, in fact, the frozen fish will gradually lose their vital signs after "resurrection".

Normal animals can hardly survive when they are frozen through because there is water in the cells, and in the cryogenic freezing stage, the water crystallizes into ice, and these crystals can puncture the cells or denature the proteins, causing irreversible damage to the body.

Extended Material: The Truth About the "Resurrection" of Frozen Fish in Water.

Some friends who live in rural areas in the north will find that some fish that are frozen by the lake in winter will miraculously come back to life after the ice melts in the spring of the next year, and there are two situations for the fish that can be resurrected.

One, it's not really frozen.

Many people see the fish in the frozen river, motionless, thinking that it is frozen, but in fact it is not, it just sinks to the bottom of the water, quietly thinking about life. Fish do not hibernate, but they regulate their metabolism according to their temperature, and in the cold season, not only their bodies but also their brains almost completely stop moving, and they look like they are dead.

Second, just locked up in an ice cellar.

In another case, it was indeed sealed in ice, but the fish itself was not completely frozen, and there was a thin layer of water between the ice and the fish, which was difficult to see with the naked eye.

In this way, completely isolated from the outside world, the fish will not die of lack of oxygen? The researchers, who studied the effects of the seasons on the crucian carp, found that in October and November, the crucian carp began to consciously reduce their energy expenditure, even if there was a lot of oxygen in the water, and they began to store glycogen in the brain and heart.

In winter, their metabolism slows down sharply, and they can only maintain glycogen for 8 minutes in summer, and can maintain 16 hours in winter, so that the black carp can survive 150 times longer under oxygen-free conditions, and in the absence of oxygen, they obtain energy through glycolysis of glycogen in the body, decompose to obtain ethanol, and excrete from the gills in the body.

They only need to keep a layer of unfrozen water on the surface of their bodies at all times, so that their bodies are not frostbitten, and they can survive until spring "resurrection".

Only some fish that are quick-frozen within a certain period of time can restart their physiological functions, and if the freezing time is too long or the fish is not frost-resistant, it is not good. Just like a human heart can be rescued after 5 minutes of death with an electric current pacing, and after 5 hours of death, there is no way to resurrect it. As the freezing time increases, the ice crystals of the water molecules puncture the cell membrane, causing irreparable damage.

Not all frozen fish can be resurrected, it also divides fish. This is a characteristic of hibernation in fish, which freezes in ice in the winter and then recovers when the weather is warmer.

Frozen fish can be resurrected because there is a fish bubble in the internal organs of the fish, and this fish bubble can make a certain amount of oxygen exist in the fish, so there will be room for resurrection.

Fish is a ectothermic animal, so its body temperature can change with the climate and water temperature, even if the fish has been frozen, but as long as it does not exceed the limit of its survival, the fish will not die. When the water temperature is very good, the fish will be more vigorous and more reproductive. If the water temperature is low, it may reduce its vitality and may stop eating.

Frozen fish can be resurrected because when frozen, only the outer part of the fish is frozen, and the inner structure of the fish is still in normal activity.

It is common to see a large live fish on the Internet that it is frozen, put in water and then resurrected.

This is because the freezing time is very short, usually within a few minutes, the fish is only frozen on the surface, but its internal organs are still normal, so it can still live after being thawed back in the water, and if it is frozen for a few hours, it will definitely not survive.

Hello, "First of all, we must understand the technical principle of freezing and resurrection." Later, it was slowly discovered that in the ultra-low temperature state, all the chemical activities and metabolism of cells (including death) will become slow or even stagnant, and as the temperature rises, the cellular activity will slowly return to activity. It is through this principle that the forest frog described above "hibernates" at a temperature of minus 16 degrees Celsius

If the live fish is not disemboweled, it is not recommended to freeze it directly in the refrigerator, if it is not stored properly, it will affect the meat quality of the fish. In particular, if you take out the frozen fish and steam it, the meat quality cannot be compared with the freshly killed one, and you can obviously feel that the frozen fish meat is old and a little firewood.

In fact, whether it is a live fish or any other animal, in fact, there are a lot of bacteria in its inner chamber, these bacteria are fine when the fish is alive, but once the fish dies, it will immediately begin to reproduce and release a certain amount of substances, most of these substances are harmful to the human body, and if the live fish is not disemboweled, it is easy to cause the fish gallbladder to freeze and crack, and the bitter water inside will enter the meat of the fish, and it is very bitter to eat, it is recommended to refrigerate, and do not stay overnight.

And the dead fish that are disemboweled, it is not recommended to keep it in the refrigerator all the time, and the preservation time is best within 1 to 2 months, which should pay special attention to the fact that after freezing, do not thaw and freeze again and again, eat a little today and thaw, and then thaw tomorrow when you eat a little, so that the fish is more likely to be bad, it is recommended to cut it in advance, freeze it separately, and thaw those if you want to eat those, and if you find that the color of the fish has turned yellow after thawing, especially in the abdomen, then it is best not to continue to eat, If brown spots are found on the head of the fish, it is the same.

In addition, many people when thawing fish, are directly soaked in cold water, so that although it can, but the speed is too slow, in fact, you can properly add some salt or vinegar to the water, and then put the frozen fish into it to thaw, so that the speed is not only faster, but also can greatly preserve a certain umami, of course, before putting it in the refrigerator, if you can open the belly is the best, and then the gills and other fishy places are heavier, and then rub it with salt, wrap it in plastic wrap, This way it will last a little longer.

Summary. It can only be frozen for about two minutes.

It can only be frozen for about two minutes.

The number of live fish holes can survive for 2 days when put in the refrigerator to ensure that the first fresh fish can survive, and the fish is directly put into the Bingzen bending box or freezer to freeze, and the fish is taken out and thawed when eating, and the fish quality is as fresh as a live fish. <>

Live fish preservation method 1: There is a line of life and death behind the nerves in the eyes of the fish, and after the fish leaves the water, the line of life and death will die immediately, and the fish will die. When the purchased live liquid is lost and the fish is not eaten temporarily, wet paper can be pasted on the eyes of the live fish, which can make the fish continue to live for 3 to 5 hours after leaving the water.

Live fish preservation method 2. Live Fish Freezing: Fish is frozen directly in the refrigerator or freezer.

When ready to eat, take out and thaw, and the fish is as fresh as a live fish. Killing fish preservation method 3 - soaking method in brine except for internal organs: the internal organs of the fish can be hollowed out without washing and scraping the scales, and soaked in 10% salt water, which can be stored for several days without deterioration.

Fish preservation method 4 - mustard preservation method: take an appropriate amount of mustard and apply it to the surface of the fish body and the inner cavity (disemboweled), or evenly sprinkle it around the container containing the fish, and then put the fish and mustard in a closed container, which can be stored for 3 days without deterioration. Killing fish preservation method 5 - hot water treatment method:

After removing the internal organs of the fresh fish, put it into the hot water (80-90 degrees) that will be boiled, and then take it out after a short pause, at this time, the appearance of the fresh fish has turned white, and then store it on ice, which can extend the preservation time of fresh fish that has not been treated with hot water by twice as long. Kill the fish preservation method 6 - steam treatment method: clean the fresh fish and cut it into suitable for trouble.

1. If you freeze the fish in the refrigerator, you can't live.

2. Because live fish is a fish with life characteristics, putting this fish directly into the refrigerator to freeze will cause the live fish to move non-stop in the refrigerator, which is easy to damage other food, and this freezing method is also more cruel, so the live fish can not be directly frozen in the refrigerator.

3. Fish meat is rich in complete protein. Fish meat contains a lot of protein, such as yellow croaker, hairtail, mackerel, silver carp, carp, crucian carp, 13%. Both marine and freshwater fish are rich in sulfur, and also contain inorganic salts such as phosphorus, calcium, and iron.

Fish also contains a lot of vitamin A, vitamin D, vitamin B1, and niacin. These are all nutrients that the human body needs.
