How to preserve crabs

Sometimes crabs that are purchased in large quantities or cannot be eaten immediately for other reasons are more wasteful if they cannot be eaten after death, so it is necessary to learn how to preserve crabs.

In daily life, you should buy fresh and energetic crabs, if you don't eat them immediately, you must not wash them with water, because the crabs washed with water are easy to die, and they will quickly rot and deteriorate, in addition, the crabs you bought back, if you are relatively thin, you can put it in a bucket with clean water for a few days, and you can put some small fish or egg yolks in the process of raising, so that the crabs can maintain their vigorous vitality.

If you are not in a hurry to eat the crab that has been tied up with a rope, you should first make sure that the crab is in a moist state, which can be flushed under the tap, and then put the crab in the refrigerator, being careful not to put it in the freezer.

The temperature in the refrigerator is best set at about 5, because the crab body is in a dormant state due to the decrease in metabolism at a lower temperature, so as to avoid the crab body from exerting physical strength and prolong the life of the crab body.

Eventually, a wet towel is placed on top of the crab, which provides a moist environment for the crab carcass, and this method of preserving the crab body can keep the crab alive for about 15 days.

However, it is important to note that the towel is always moist at all times during this time.

If the crab is not tied with a rope, it can be tied up with a rope or placed in a net bag and a drawer in the refrigerator, and after an hour of this place, the crab will also enter a dormant state and no longer crawl in the case of low temperatures.

If you are still worried that the crab will die during this time, the crab is steamed and then cooled, after urinating, put the steamed crab into a fresh-keeping bag, and then put it in the freezer for refrigeration, so that it can be stored longer, just take it out and steam it, but for the sake of freshness and health, it is not recommended for everyone to keep it for too long, because the crab is stored for too long, it will affect the taste, so it loses its deliciousness.

In addition, it should also be noted that dead crabs must not be eaten, because once the crab dies, bacteria will multiply in the crab body, as we all know, the hidoxylic acid in the crab will decompose to produce histamine, which is a toxic substance, with the prolongation of the death time of the crab, the more histamine accumulated in the human body, the more toxic it is, even if it is cooked, the toxin will not be easily destroyed, if you eat a dead crab will cause poisoning.

Here's how to preserve crabs:

1. Store in the refrigerator fresh-keeping room.

When buying hairy crabs, merchants generally use ropes to tie up the crab legs, so we don't have to untie them after we go home, and directly tie them to the refrigerator to avoid the crabs struggling and reduce the consumption of the crabs' physical strength. After refrigerating the crab in the refrigerator, we put a damp towel on the crab and it's fine.

2. Put it in a basin and store it.

Prepare a slightly taller and larger pot to prevent the hairy crabs from escaping. Place the hairy crabs flat in it, taking care to lay them flat and not stack them. Then start adding water to it, the amount of water is about half of the height of the crab, you must not put too much water, otherwise the crab will not be able to breathe, and it will die after a long time.

3. Keep it in the bathtub.

If you don't use the bathtub at home, you can temporarily let the crabs keep it inside. Put all the crabs in it, and then add some water, the amount of water is also not too much, similar to the method above. If we can, we can also add some small fish and shrimp to it.

【Precautions for Storing Crabs】:

1. When preserving crabs, the water must not submerge the whole crab, which will suffocate the crab to death, and the correct way is to cover the crab's mouth with water, so that the crab can breathe normally.

2. When you change the water for the crabs, change them every other day, and every time you change them, don't change all the water, only half of the water in the basin can make the crabs more adaptable to their living environment, so that the crabs can live longer. When you feed the crabs, don't feed them too much or too often, feeding too much and too often, it will lead to poor water quality, so that the crabs die.
