Why can dead pike crabs be eaten but crabs can t?

If the death time is not long, it can be taken but the death time is too long, so it is not recommended to take it.

Dead crabs are very, very easy to dehydrate, not steamed, and immediately frozen very, very easy to cause the crab sticks to lack of water, until they are unfrozen and cooked, the crab shells will become more and more empty. Steaming and then freezing can reasonably lock in the moisture, although there will be ice analysis in the case of reheating, but the amount of dissolution is much less than the previous one. Dead crabs do not need to be frozen, as they will evaporate and become smelly and mildewy.

Since hairy crabs are cold-blooded, live crabs can be stored in the refrigerator. When storing, the hairy crabs are neatly stacked in a small styrofoam box or a bamboo frame, put some ice cubes in it, and cover it with a cotton towel, so that the hairy crabs can be stored for a week.

This is because the seawater itself has a certain bactericidal effect, and the bacteria do not multiply so quickly after the sea crab dies. The salvaged sea crabs are generally frozen quickly, and the bacteria have not had time to multiply, so the frozen sea crabs can be eaten. However, if the sea crab is exposed to deterioration at room temperature after death, it is also not edible.

There will be a lot of bacteria in the digestive glands of crabs, and after the crab dies, under the right environment, the bacteria will multiply, and then cause the digestive glands to rupture, and heavy metals and bacteria will contaminate the crab meat.

River crab is a high-protein aquatic product, the body basically does not contain salt, after the river crab dies, the high protein immediately begins to deteriorate, and the bacteria will multiply faster. Therefore, the rate of deterioration and decay is also faster. In order to sell **, river crabs are all transported according to fresh logistics, and they will not be frozen and frozen, and death cannot be dealt with as soon as possible.

Moreover, a large number of centralized transportation, and the life and death of river crabs, polluting each other. As a result, dead crabs are inedible.

Barracuda crab is a sea crab with a certain salinity in its body, which can prevent a large number of bacteria from multiplying in a short period of time. In addition, sea crabs cannot survive for a long time out of the water, so they are frozen quickly to ensure logistics and transportation. The transportation and sales of the whole cold chain are naturally much safer than the river crabs that are transported and sold according to the fresh food.

Crabs produce toxins after death. Crabs like to eat animal carcasses and rotting food, and the digestive tract contains a lot of substances that are harmful to humans. When the crab dies, the bacteria multiply.

Barracuda crabs have been dead for a long time and are not recommended to eat. It is a sea crab, which has a better living environment than crabs and has relatively few bacteria.

Barracuda crabs are sea crabs that live at 5-30 meters on the bottom of the sea, and their bodies are high in salt, so they are slower to breed bacteria than river crabs after death. However, bacteria can also grow, so it is not recommended to eat dead crabs and sea crabs.

Why can you eat a dead crab, but not a crab, I think that if this kind of crab is dead and you eat it again in the future, then it will breed a lot of bacteria, causing us gastrointestinal discomfort.

Hello, pike crab is also a type of crab, and it also belongs to seafood, so it is best not to eat dead pike crab.

So that these can be eaten crabs can also be eaten, I have eaten them, and I don't feel anything abnormal. It's just that the taste is not as good as fresh.

You can eat it, just don't take too long.

Barracuda crabs are sea crabs.

They generally live in salty water, and their ability to survive is weakened after being separated from seawater, so it is easy to die after being salvaged.

The reasons why pike crabs die easily are as follows:

1. The pike crab is a sea-born crab that needs seawater, and it can survive if it is put into fresh water for a short time, but it will soon be due to osmotic pressure.

The change will cause the crab body to absorb water and swell to death.

2. After the oxygen is sealed during transportation, the salt analysis of the seawater after heating causes the seawater to deteriorate and turbidity, and the death of hypoxia.

3. The oxygen injected during transportation is too pure, resulting in oxygen poisoning or using compressed air with less oxygen to inject oxygen, so that the oxygen is quickly exhausted, causing difficulty in breathing.

And death. Barracuda crab, commonly known as "white crab" in some places.

Because the cephalothorax is a shuttle, it is called a shuttle. The ** of the carapace has three protrusions, so it is also called "three-wart pike crab", which belongs to arthropods.

Males have a pointed and smooth umbilicus, with long chelae and a bluish shell surface; The female has a round umbilicus with villi hairs, and the shell surface is ochre or spotted. The crab meat is fat and delicious, has high nutritional value and economic value, and is suitable for temporary breeding and fattening of seawater. cephalothorax fusiform, almost twice as wide as long; The cephalothorax surface is covered with fine granules, with 2 granular transverse embankments and 3 verrucous protrusions; forehead with 2 sharp teeth; The anterior lateral margin has 9 acute teeth, and the terminal teeth are long and spiny, protruding outward.

chelicerae stout, longer than cephalothorax; The long nodes are prismatic, and the male long nodes are more slender, with 4 acute spines on the anterior margin.

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.

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.

Dead crabs produce large amounts of histamine. Histamine poisoning occurs when people 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 just eat a little dead crab meat.

People who are allergic to histamine can cause a reaction even with a single bite. For example, after 10 minutes to 3 hours of consuming dead crabs, symptoms such as redness of the cheeks, redness of the chest and whole body**, conjunctival hyperemia, headache, dizziness, tightness or banding in the chest, discomfort and irritability.

Dead crabs must never be eaten. Because another important cause of dead crab poisoning is bacterial infection. In general, wild crabs live in a worse environment than artificial crabs and marine crabs.

Once dead, bacteria inside and outside the body will multiply, breaking down the crab meat and producing toxins. Comparatively, the risk of bacterial infections is higher, and people are more susceptible to bacterial infections after eating.

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.
