Can you eat crabs after they die?

Preface: The taste of crabs is very good, many people like to eat crabs, but when eating crabs, you will find such a problem, that is, the crabs bought back have died because of improper maintenance, and a large number of bacteria will be produced when the dead crabs are killed, such bacteria react with the proteins in the crab's body to produce histamine, this substance is toxic, and if ingested, it will produce symptoms of dizziness and nausea, so you must not eat dead crabs. <>

If the crab has been dead for a period of time, the protein environment in the crab will provide a good breeding ground for bacteria, and the longer the time, the more these bacteria, when the crab is bad, there will be a smell, if you eat it in the stomach, it will produce dizziness, nausea and diarrhea symptoms, so you must not eat dead crabs for waste, which is a completely disregard for your own health. We can smell the crab before eating it, and if we find that it has gone bad, then we can throw it away immediately. <>

If a friend of ours sends a few boxes of crabs and can't eat them all for a while, we can make crab sauce so that we can keep them for a longer time and taste the deliciousness of crabs at the same time. When making crab paste, it is relatively simple, we only need oil, salt, and at the same time choose fresh crab, so that the taste will be better. If refrigerated, we best eat it within a week.

If it is frozen, we can keep it for three months. <>

Some people will have such a habit when cooking, if the meal cannot be eaten, then it can be kept for a long time and must be eaten, this idea is very wrong, because in the process will produce a large number of bacteria, if you eat it in the stomach, it will have a certain impact on life and health. I have seen such a delicacy before**, a food blogger ate a bad lobster, and after seeing such a footage, it really makes people feel very disgusting.

You can't eat it, after the crab dies, it is very cold, which will affect your health and produce toxic substances.

No, because after the crab dies, it will breed a lot of bacteria, and it is not good for the human body after eating it.

Experts say that chilled crabs can be eaten with confidence, but it is best to buy and eat them now, not to store them in large quantities, and not to thaw them repeatedly.

When a crab dies, the parasite quickly breaks down the crab's body and releases toxic substances. At the same time, the bacteria multiply, not only the meat quality and taste of the crab will be greatly reduced, but also the nutrients will be greatly lost. Therefore, once a dead crab is eaten by mistake, symptoms of nausea, vomiting and abdominal pain will generally occur.

Reason 2: When the crab is dying or dead, the hidoxyl acid in the crab body will decompose to produce histamine, histamine is a toxic substance, with the prolongation of death time, the crab body accumulates more and more histamine, and the poisonous gas is getting bigger and bigger, even if the crab is cooked, this toxin is not easy to be destroyed; Too high ammonia nitrogen must be excreted from the kidneys, so eating dead crabs is very bad for the kidneys, and those who eat dead crabs may also have symptoms such as vomiting, abdominal pain, and diarrhea. In addition, even half-dead "legged crabs" should not be eaten.

Absolutely can not eat Oh, there is a great risk of eating dead crabs, and there are a lot of bacteria, there have been people who have eaten dead crabs and ended up in the hospital, in fact, crabs can not be eaten can be put in the refrigerator, but they can only be put in the refrigerator for a maximum of 2-5 days, put the crabs in the refrigerator, and then cover them with a wet towel, the temperature is 3-6 degrees, and it can be stored for a few days. Crabs are cold, although they are delicious but they can't eat too much, otherwise it will affect their health, so I recommend a few crabs to everyone, which is also the season to eat crabs.

The crab can be steamed at the simplest time, the taste is very delicious, and the original taste of the crab can be guaranteed, and the method is also very simple, clean the crab simply, then take a plate, put a few slices of ginger underneath, turn the crab's belly upside down and put it on and then put it in the pot after the water boils, generally steam it for 15-20 minutes on high heat, depending on the size of the crab, the 2 taels I ate before are 20 minutes suitable, and you can eat it directly after steaming, but how can you eat the crab without the sauce,Prepare a bowl with minced garlic and ginger, then add vinegar and light soy sauce, but with crab can bring out the deliciousness of crab.

The method of stir-fried crab is also very simple, the same cut the crab and then dip it in cornstarch and set it in the pot and then put it out, directly put the green onion, ginger and garlic in the pot and then add the crab to stir-fry over high heat, here add a spoonful of bean paste to add fragrance, then add cooking wine, light soy sauce and sugar to fry over high heat, you can pour a little water on the side of the pot, not too much, add a little sesame seeds before serving, such a crab sauce is full of fragrance.

Do you know how to make these three types of crabs?

Don't eat dead crabs, even crabs that have just died.

Because crabs are omnivores, they carry a lot of bacteria and viruses. The metabolism of live crabs can compete with microorganisms and inhibit their reproduction; After the crab dies, the microorganisms will use its rich nutrients to multiply rapidly, causing the crab to spoil and produce a variety of toxins. Food poisoning symptoms such as fever, vomiting, abdominal pain, and diarrhea may occur after eating.

Crabs cannot be eaten when they die, because after the crab dies, it will cause many pathogenic microorganisms and parasites to multiply. If you eat dead crabs, it will cause a high incidence of intestinal infectious diseases and cause diarrhea, which is harmful to health.

The protein and other nutrients in the dead crab have been decomposed and consumed, and if you eat it again, it will not play the role of supplementing nutrition, and its nutritional value will be greatly reduced.

The components in crabs, especially the decomposition of proteins, can cause allergies in the body, ranging from itching to allergic asthma and endangering the body. Crabs are cold in nature, and if they eat more, they can easily cause diarrhea.

When crabs die, they cause the multiplication of pathogenic microorganisms and parasites. If you eat dead crabs, it is easy to cause diarrhea due to intestinal infection, which is harmful to health.

Try not to eat it, because dead crabs have a lot of bacteria and viruses, and eating them may cause poisoning or other adverse reactions, crabs are delicious, but try not to eat more, otherwise they will cause indigestion, including stomach pain or vomiting.

I don't think you can eat dead crabs because most of them are poisonous.

It is better not to eat dead crabs, first of all, they are not fresh, and they are easy to spoil, and they are also easy to change their taste, and the body is not good

1. It mainly depends on the time when the crab dies and the environment in which it is preserved. If the crab is in.

If you die at room temperature of 20 or 30 degrees, you can't eat it for more than two hours, because the crab may also carry bacteria, parasites and silt and other dirty things, plus the protein and fat content in the crab is rich, and the dead crab is easy to become the nutrients of bacteria, and the harmful substances such as cadaverine and histamine will be harmful to human health after being decomposed.

2. If the crab has been kept in the refrigerator, then even if it dies, the bacterial reproduction will be inhibited by low temperature, and it can generally be eaten within 1-2 days of death.

Nowadays, many people like to eat game, the new crown virus before this time, may be brought to humans because of some viruses on animals, but people always feel that the taste of game is the best, so they will often eat some animal offal or other things in the mountains, many people don't know, after the animal dies, there will be a lot of protein in the body, some large amount of decomposition, produce some histamine, these will increase the level of histamine in the blood of people, if you use it improperly, Or some people with allergies use it, there will be some light red on your **, resulting in physical discomfort, and even sometimes you may have headaches, or itching of some body parts, these are the feelings that lead to eating dead animals, such as these feelings should be immediately sent to the hospital**. <

As we all know, crabs live in shallow water, there will be some microorganisms or animal carcasses in the water, and crabs will take them as the main food to survive, when the crabs are alive, the viruses in their bodies will be discharged through some organs in the body, if the crabs are dead, these viruses or bacteria will multiply in large quantities, and penetrate into the crab's meat, if you eat the crab at this time, you will have diarrhea, vomiting, and nausea, After the crab dies, or before the crab dies, the bacteria in the crab have begun to multiply in large quantities, and some biological toxins will breed, so after people use it, it is more likely to cause food poisoning, and some people will ask whether they can be eaten after high temperature sterilization, these are not allowed, even if it is a small piece. <>

Mainly because there is a toxin in his body, called histamine, after he is eaten by the human body, it cannot be decomposed, and this poisonous gas will only accumulate more and more, even if the crab is cooked, this toxin will not be destroyed. <

Can't eat. Crabs secrete some toxins after death to break down their own flesh, which is not very good for the human body, so try not to eat dead crabs.

It is not allowed to be eaten, and dead crabs will be poisoned, which will also affect the health of the body, and a lot of bacteria will appear.

I don't think you can eat dead crabs because they contain a lot of toxins, so we must pay attention to this aspect.

It is not allowed to be eaten, because there are microorganisms and bacteria in the body of crabs, and it is not good for the body after eating.

If you can't eat it, the dead crab will rot, which will cause a lot of bacteria and a lot of parasites.

1 The crab can still be eaten after it dies, but it depends on how long he has been dead, if it is a crab that has died for a short time, and she has not deteriorated at her time, then such a crab can still be eaten, and it can be eaten immediately after it is washed and steamed directly in the pot. But after death, crabs cannot be stored for a long time.

If the crab has been dead for a long time, it is not fresh at all when it is tattooed, and there will be a distinct fishy smell, then such a crab cannot be eaten. Because after the crab dies for too long, not only will it rot and deteriorate, but the hidoxyl acid in its body will also release histamine, which can produce a toxic substance to the human body, which is not afraid of high temperatures, and people will absorb a large number of toxic substances even if they eat it after steaming, which will be detrimental to human health.

2. Try to avoid eating those dead crabs in life, if people eat dead crabs, they are prone to food poisoning, because the crab is in the process of dying and struggling, the hidooxyacid in its body will be decomposed and converted into the harmful substance histamine, which will harm multiple organs in the human body after entering the human body, and will make the food boiled appear obvious symptoms of attack poisoning.

Crab is a particularly large number of parasites in aquatic food, and the parasites in his body will multiply in large numbers after the crab dies, but after the crab dies, it will let the parasites enter the body, and they will multiply rapidly in the body, which will lead to a high incidence of parasitic diseases, making people have a variety of adverse symptoms such as body emaciation and abdominal pain.

3 crab is a particularly strong vitality of the existence, it can be placed in the refrigerator refrigerated preservation, but before preservation, to prepare a suitable size foam box, and then use a rope to tie all the crab's legs and feet, put it in the foam box, after all the fill, to add an appropriate amount of water, wipe the surface of the crab, and then seal the cover of the foam box, clear the sail directly into the refrigerator compartment can be.

After the fresh crab is purchased, if you don't want to eat it in a short time, you can put it in the freezer of the refrigerator to preserve, and before preservation, you should also put it into the foam box, and before loading, you should tie all the legs and feet of the crab, and put it tightly in the foam box, and then put it directly into the freezer of the refrigerator, so that you can keep the crab fresh to the greatest extent, take it out and melt it when eating, and steam it directly.

1. The crab is dead and cannot be eaten.

Crabs are scavenging wild animals that accumulate a lot of bacteria and parasites in their bodies. After the crab is dying and dying, the lactic acid in the crab's body will increase, causing the bacteria to accelerate their reproduction and spread, and the bacteria will decompose the amino acids in the crab's body in the process of diffusion, resulting in the production of "histamine", a harmful substance, which is not easy to be destroyed even at high temperatures, which has an impact on human health.

2. After the crab dies, because it will release harmful substances, which is not good for the human body, so after eating, the human body may have allergic reactions such as nausea, vomiting, abdominal pain and diarrhea.

If you eat too many dead crabs, it can also lead to food poisoning, that is, symptoms such as asthma, weakness in limbs, fainting, and dizziness.

3 Live crabs generally blink their eyes, so when you look at them, you can touch the eyes of the crab with your hands, and the eyes of live crabs will be more flexible.

If you want to judge whether the crab is alive, you can try to straighten the crab's legs, and if it quickly springs back to the curved state, it means that the crab is alive.

Live crabs move when placed in water. Untie the strap of the crab, put it in clean water, and observe for about ten minutes, if the crab is moving, it means that the crab is alive, and if it is not moving, it is dead.

41. Tie the crab with a strap to reduce the physical strength of the crab to a certain extent, and the crab will be stored for a longer time.

2. Put the crab into the freezer layer of the refrigerator, which can preserve the freshness of the crab to a certain extent and avoid dying too quickly.
