Compared to hairy crabs and pike crabs, which type of crab is edible after death?

Many friends will ask: hairy crab and pike crab.

In comparison, which kind of crab can be eaten after death? The answer is pike crabs.

Today, let me take you to understand why barracuda crabs can be eaten after death, but hairy crabs cannot be eaten after death.

First of all, we need to understand that pike crabs belong to sea crabs.

Hairy crabs belong to river crabs.

As long as the dead sea crab is chilled, it can be eaten, and the pike crab is a sea crab, and as long as the pike crab is in a chilled state after death, then it can be eaten for us. However, hairy crabs belong to river crabs, and as long as river crabs are dead, they are inedible whether they are chilled or not.

Why can't hairy crabs be eaten after they die? It is because after death, hairy crabs produce a histamine-like substance.

Substances, histamine-like substances are toxic, and if people eat dead hairy crabs, they will have diarrhea, nausea, and vomiting. Therefore, dead hairy crabs are not edible.

Next, let's take a look at the practice of pike crab and hairy crab. One of the most common ways to eat it is steamed. Steamed over water, put green onions, and ginger for 10 minutes, and then make your own favorite dipping sauce, or eat it directly, such a steamed hairy crab or pike crab is very delicious.

In fact, we can also try to make meat and crab pot at home. The ingredients we need to prepare are crab, chicken feet, shrimp, potatoes, rice cakes, onions, red and green peppers. First, we need to put all the ingredients in a small bowl. These ingredients are: star anise, cinnamon.

Fennel, dried chilies, shallots, ginger, garlic. Cut the chicken feet with cooking wine.

Soak it and fry it to get fishy, cut the pike crab into small pieces, wrap the pike crab in starch, fry it in an oil pan, and put the shrimp line of the shrimp.

Rip it off. Stir-fry the spices and bean paste in a frying pan, add chicken feet, sweet noodle sauce, dark soy sauce, light soy sauce, oyster sauce, simmer for another 10 minutes, add side dishes and fried crab, and finally add red and green peppers, so that the delicious family version of the meat and crab pot is ready.

That's all for me.

Barracuda crab is the kind that can be eaten even if it is dead, because it is a sea crab, and it can be eaten even if the sea crab is dead, but not the river crab, after the river crab dies, there will be a lot of toxins in the body, and it cannot be eaten.

I think pike crabs can be eaten after death because there are many people who think so.

Hairy crabs. Many people choose to eat crab every winter because it can satisfy their taste buds.

Blue crabs and hairy crabs can't be eaten after they die, because they parasitize many bacteria in their bodies, which can easily cause harm to the body, while pike crabs can be eaten because its bacteria don't multiply so fast, and frozen seafood can be eaten.

Fresh crabs are indeed very delicious to eat, but many of us buy crabs from the market are often some dead, for the meat quality of dead crabs, we must eat properly, otherwise it is easy to cause some damage to the body.

Blue crabs and hairy crabs cannot be eaten after they die.

Blue crabs and hairy crabs are freshwater farming, they die within two hours, the body will quickly produce some toxic ingredients, some expert studies have shown that after two hours of death, the bacteria in the body will quickly surge by about 20%, if accidentally eaten after it is easy to cause a large number of bacteria in the human body to cause gastrointestinal discomfort, severe cases may appear poisoning symptoms.

Barracuda crabs can be eaten normally within 24 hours after death.

Barracuda crabs are seawater farmed, and the bacteria do not multiply so fast after they die, and most of the pike crabs will be quickly frozen after they are hit, and the bacteria will not have time to reproduce at this time. In addition, studies have shown that barracuda crabs will produce a large number of bacteria in their bodies 24 hours after they die, so as long as they die normally within 24 hours, they can be eaten normally, and their taste is still relatively delicious.

Dead crabs are best not to eat.

Personally, I think that whether it is a blue crab, a hairy crab or a pike crab, if it dies for too long, it is best not to eat it, especially those that have a particularly unpleasant smell after buying, and they are often already smelly, and the body contains a lot of bacteria. If you often use some dead crabs, it will lead to parasitic infections in the body, and even symptoms such as stomach erosion, and severe cases may be poisoned as mentioned before, if you especially want to eat crabs, it is best to go to the market to buy fresh ones.

This is because blue crabs and hairy crabs are river crabs and have more bacteria on their bodies. Whereas, pike crabs are sea crabs.

Because blue crabs and hairy crabs belong to river crabs, they secrete harmful substances after death. Whereas, pike crabs belong to sea crabs. Less pollution of seawater.

It is because blue crabs and hairy crabs produce toxic substances after they die, while barracuda crabs still have certain nutritional value in their bodies after they die.

It's edible. The pike crab is a sea crab, and the sea crab is dead, but as long as it is chilled, it can be eaten.

The body color of the pike crab varies depending on the surrounding environment. Individuals living on sandy bottoms have a light gray-green cephalothorax, a round white spot in the anterior gill region, most of the chelicerae are purplish-red with white spots, part or all of the ventral surface is white, the first three pairs of long steps and wrists are also white, the palms are bluish-white, the soft bristles are brown, the knuckles are purplish-blue or purple-red, the fourth pair of steps are green with white spots, and the fingertips are purple-blue. Individuals living among seagrass have a darker body color.

It is omnivorous, eating fish, shrimp, shellfish, and algae, and even eating the same kind, and likes to eat animal carcasses.

The cephalothorax is fusiform, slightly raised. There are 3 prominent wart-like bumps on the surface, 1 in the stomach and 2 in the heart. Its body shape is like an oval, and the two ends are pointed like a weaving shuttle, so it has the name of the three-wart pike crab.

Each of the two anterior lateral margins has 9 serrations, and the 9th serration is particularly long, extending to the left and right. The frontal margin has 4 small teeth. There is a pair of stalked compound eyes on both sides of the forehead that can be rotated.

There are 5 pairs of thoracic feet. The stings are well developed, the long segments are prismatic, and the inner margin is blunt. The knuckles of the fourth pair of feet are flat and wide like a paddle, suitable for swimming.

The abdomen is flat (commonly known as crab navel), the abdomen of male crabs is triangular, and the abdomen of female crabs is round. The back of the male crab is tea-green, the female crab is purple, and the ventral surface is grayish-white.

1. Touch your eyes. Live hairy crabs shrink when they touch their eyes with their hands, while dead crabs usually bulge out of their eyes and do not move.

Second, see if you spit bubbles. If the live hairy crab is more energetic, it will spit out a circle of small white bubbles, while the crab with bad spirit may not have this characteristic, which distinguishes the life and death of the hairy crab.

Features must be observed.

Third, untie the rope to see the state. If there is no response after touching the eyes, you can untie the rope tied to the crab and put it on the table to see if it can still crawl or retract its paws, if not, it means that it is dead and must be discarded.

When a hairy crab is dying or has died, the parasitic bacteria in its body will multiply and spread into the crab meat, causing the protein to break down to produce histamine.

The longer the crab dies, the more histamine accumulates in the body, and the more toxic it becomes. Even if the dead crab is cooked thoroughly, the toxins are still not easily destroyed, and the ammonia nitrogen is too high.

It must be excreted from the kidneys, so eating dead hairy crabs can easily cause kidney disadvantage. What's more, there will be adverse reactions such as nausea and vomiting, flushing of cheeks, and rapid heartbeat after eating dead hairy crabs.

To sum up, you must be wary of eating dead crabs when eating hairy crabs, if you eat Yangcheng Lake hairy crabs in restaurants.

1. Ginger vinegar can be used as a seasoning when eating crabs, which can help digestion and sterilization; 2. Try to choose the nearest Yangcheng Lake hairy crab store to buy fresh hairy crabs.

After the crab dies, the bacteria immediately begin to decompose the meat inside the crab shell, if you find that the weight is light, the meat inside is empty, it means that there are a lot of bacteria, easy to food poisoning, it doesn't matter if you just die.

Dead pike crabs can no longer be eaten.

Dead crabs produce large amounts of histamine in their bodies. Histamine poisoning occurs when humans eat dead crabs. Because histamine is an allergic poison, it can also be said to be allergic food poisoning. Don't think it's okay to eat just a little bit of dead crab meat.

People who are allergic to histamine can cause a reaction even if they take a bite. For example, after eating a dead crab for 10 minutes and 3 hours, symptoms will appear, such as redness of the cheeks, flushing of the chest and the whole body, and conjunctival hyperemia of the eyes, as well as headache, dizziness, chest tightness, general fatigue and irritability.

Another important cause of poisoning in dead crabs is bacterial infection. Once the crab dies, bacteria inside and outside the body multiply, breaking down the crab meat and producing toxins. Comparatively speaking, the risk of bacterial infection is higher, and people are also more likely to develop bacterial infections after consumption.

For dead pike crabs, it is best not to eat them as much as possible. Although the crab meat is delicious and nutritious, dead crabs are still taboo to eat; Because crabs like to eat decaying substances such as animal carcasses, their gastrointestinal tracts often carry pathogenic bacteria and toxic substances, and once they die, these germs multiply in large numbers; In addition, the crab body also contains more histidine, histidine is easy to decompose, can produce histamine and histidine-like substances under the action of decarboxylase, especially when it dies, histidine decomposition is more rapid, with the longer the crab dies, the more histamine accumulates in the body, and when histidine accumulates to a certain amount, it will cause poisoning.

Generally speaking, sea crabs that die, as long as they are chilled, can be eaten, and river crabs that die must not be eaten. Sea crabs survive for a short time out of the sea, and they are generally frozen and kept fresh immediately after leaving the water.

If it is a frozen pike crab, the ice water has not completely melted during transportation, or the box still feels a little cold, indicating that the crab is still fresh, and it is recommended to put it in the freezer immediately after arriving home. Remember that the freezer is not a refrigerator, after one day, if you want to eat it on the second day, you can take out the crab in the freezer and put it in the refrigerator, and you can eat it when it is thawed. In fact, it is best to marinate frozen pike crabs with salt, and then put them in the freezer, when to eat them and take out a few, and the crab is easy to cut with a knife in a frozen state, and it is also stylish.

How can you tell if a crab is dead or alive?

One look: look at the color.

Fresh crabs have a bright red back and a bright white belly when cooked, while dead crabs have a dark red back and a grayish belly with a gray color.

Second smell: Dead crabs have a rotten taste.

If you think that the crab itself is very smelly, that smell should be the fishy smell of seafood, and you won't feel fishy after you get used to it; Dead crabs, on the other hand, have a special smell when their meat is rotten, which is different from the rancid smell of spoiled food.

Three pinching: After the dead crab is cooked, the shell will be soft and the meat will be loose.

When a live crab is cooked, the shell is hard, and if you press it with your fingers hard, the shell will not dent, while the shell of a dead crab will become soft because the flesh begins to rot, and it will sink down when you press it lightly with your hand.

A frozen pike crab should be a good thing because it is definitely wild (the crab dies as soon as it is caught) and the taste should be more delicious than that of farmed. But if it's very frozen, steaming won't work, you can put it in cold water to thaw, then wash and cut into pieces, salt or minced garlic.
