Can you still eat the pike crab when it dies?

The pike crab has been dead for a long time and cannot be eaten.

Dead crabs contain a lot of harmful substances, and eating them can seriously damage your health, so it is best not to eat dead crabs.

The dangers of eating dead crabs.

1. Most river crabs grow in filthy ponds and like to eat dead fish, dead shrimp, and other rotting animal carcasses. As a result, they are susceptible to bacterial infection. In general, crabs are contaminated with a large number of microorganisms both inside and outside.

While alive, river crabs can excrete bacteria from their bodies through metabolism. Once dead, the bacteria in the body will multiply in large numbers, decomposing the crab meat, and some bacteria will also produce toxins.

2. In fact, the poison hidden in the dead crab is far from the truth. Crabs also contain more histidine, which is easily broken down and can produce histamine and histamine-like substances under the action of decarboxylase. Especially when the crab dies, histidine breaks down faster.

The longer the crab dies, the more histamine accumulates in the body. When histamine accumulates to a certain amount, consuming it can cause poisoning.

3. Among all the toxins, there is a very important part - ammonia. How can river crabs still carry ammonia? This needs to start with its rich protein content.

Chinese mitten crab contains a lot of protein. When it dies, the proteins in the body break down into ammonia. After the dead crab is eaten into the human body, the excess ammonia must be excreted through the body, and this process can cause health hazards.

It depends. Portunid. It belongs to sea crabs.

After the pike crab ** is fished out of the sea, it does not survive for a long time, and what is generally sold in the market is dead pike crab, which is not dead for a long time and is edible.

Because the sea area where the pike crab lives is relative to the river crab.

It is relatively clean, there are not so many bacteria and microorganisms in the body, and the time for bacterial invasion and deterioration will be slower, so as long as it is scientifically and reasonably refrigerated, the dead pike crab can still be eaten.

However, if the pike crab that is relatively dead has obvious deterioration phenomena such as deterioration such as flavor loss and softening of the shell, it will contain more bacteria inside, and this kind of pike crab is not edible.

Barracuda crabs are generally not edible when they are sent to death.

Barracuda crab is a kind of seafood, which generally feeds on decaying substances such as some animal carcasses, so after death, it will decompose more histamine substances, and the human body will cause food poisoning after eating.

If the pike crab is just dead, it can be eaten in small amounts at this time, and it will not affect human health: if the pike crab has been dead for a long time and has obvious deterioration, it can not be eaten at this time, and it can only be discarded at this time.

Although acidic substances are somewhat dangerous, it is okay to be careful and careful. The key is that it is not harmful to the glass of the fish tank, so there is no need to worry about the glass being spent.

If the pike crab is stored properly, such as being preserved and frozen, and the pike crab does not appear smelly and mucus the next day, it means that the nutrients of the pike crab have not been lost at this time, and it will basically not produce harmful substances, and a small amount of food will also have adverse effects.

However, if the pike crab has an obvious peculiar smell and deterioration, do not continue to eat it, because the pike crab has spoiled at this time, and eating it may cause diarrhea, bloating and other symptoms, and in severe cases, it may also cause food poisoning, which is not conducive to health.

1. It can be eaten within 2-4 hours at room temperature

If the ambient temperature at room temperature is relatively high, it is best to eat it within 2 hours after death, and if the temperature is relatively low, it can be eaten in small amounts within 4 hours, and it is best not to eat it for more than 4 hours.

2. It can be eaten within 24 hours under refrigeration

If it is refrigerated in the refrigerator, then it can still be eaten within 24 hours of death, and the more toxic substances in the body of the pike crab after 24 hours, it is easy to be poisoned if you eat it again.

3. You can eat it within 7 days after freezing

The freezing temperature is very low, which can inhibit the growth of bacteria, so the pike crab within 7 days of death can be eaten in small amounts, but at this time, the nutritional value is lost a lot, and the meat is not tender enough, try not to freeze it for so long.

How to preserve the crab.

According to the size of the freezer compartment of your refrigerator, find a suitable foam box, which can be placed in the freezer in advance to see if it fits. Then tie the legs and feet of the pike crab and put it in a foam box. Put them next to each other one by one, try to squeeze one layer and then add more.

Add water to the foam box until the water reaches the surface of the crab. Then close the foam box and put it in the freezer compartment of the refrigerator to freeze. When you want to eat pike crab, just take it out and thaw it, so that the preservation of pike crab can ensure the freshness of pike crab to the greatest extent.
