How to store crabs so that they don t go bad, and how do you keep crabs from going bad?

There are two ways to preserve crabs:

Method 1: Preservation of live crabs.

Prepare a large pot.

I choose a lively crab and put it in.

Pour cool water into the basin.

It is best to use purified water.

It's less than half the size of the crab.

To the back of the shell is fine.

This makes it easier for it to breathe.

Then store at room temperature.

When picking crabs.

Touch it in the eyes.

If the reaction is fast.

It shows that the crab is very energetic.

It can be stored for a few more days.

Method 2: Cook and preserve.

Crabs are cleaned.

Open the ventral lid. Wash excrement.

Rinse with running water.

Put boiling water into a pot and steam.

Let cool at room temperature. Place in the freezer.

When you eat it, take it out and heat it up.

That's it for two ways to preserve crabs.

Crabs can be stored in the refrigerator for three or four days.

Generally speaking, live hairy crabs are brushed, tied with rope, and then covered with a wet towel, which can be stored for three or four days, but if it is more than a week, the crab basically dies.

You can put the live crab in a plastic bag, don't tie it tightly, so that the crab can breathe and can be stored for about eight days, of course, this kind of food is still bought and eaten, so that you can eat a better taste.

Many people know that dead crabs are not edible, and most of this food is river crabs, so once they die, they cannot be eaten, which must be noted.

Generally speaking, you can wait for the crab to cool down and wrap it in a plastic wrap room refrigerator, preferably frozen, and not more than noon the next day. When eating, be sure to go back to the pot and recook it, so that the taste will not be bad.

Crabs must be covered well in the refrigerator, because when this food comes into contact with those foods, it will produce toxic substances, and it is okay to eat them the next day.

If you keep it for a short time, you can directly cover it with plastic wrap and store it in a cool and ventilated place.

Crabs can be frozen and preserved.

Raw crabs: Crabs need to be frozen before being transported over long distances. Low temperature can inhibit the activity of fungi and parasites in crabs, and can delay the degradation of its own protein, which can achieve freshness, almost does not affect its nutrition and taste, and can be eaten safely.

Cooked crabs: Cooked crabs can be eaten overnight, but they are not safe in the refrigerator, and long-term storage of mature crabs is still easy to cause poisoning and killers. The principle is histidine.

In the remaining crabs overnight, histidine will be broken down into histamine under the action of some microorganisms, which can kill pathogenic microorganisms after heating, but cannot destroy toxins, so eating long-ripe crabs can also lead to histamine poisoning. So as soon as possible.

1. If the weather is not very hot, you can keep the crab in a plastic bucket with a large volume and a smooth inner wall, and put a small amount of water and food in it. 2. Put the crabs in the refrigerator and keep them, remember to tie the crab legs and cover them with a wet towel.

The crab legs are tied to reduce the amount of activity of the crab, and the wet towel is covered to maintain its humidity, which can prolong the freshness of the crab.

Crabs should not be fed for too long, and it is recommended to eat them as soon as possible to avoid leaving them for a long time to reduce their flesh or die.

Crabs must be eaten fresh when cooked, if they die due to improper preservation, do not eat again, the dead crabs will not only lose a lot of nutrients, but also may produce harmful substances to the human body.

Short-term storage: Prepare a basin, put it in cold water, add some salt, and the depth of the water will allow the crab shell to be exposed to the water. For a long period of time, it is recommended to cook and put it in the refrigerator.

If you store fresh crabs in the refrigerator, they can be stored for 5-7 days. Whereas, when stored in the freezer compartment of the refrigerator, it can be stored for 15-30 days. However, it is stored at room temperature without any treatment, and it can only be stored for a few hours.

How do you keep crabs fresh?

1. Short-term storage: 1. If it is stored for a short time, such as eating it after a day and a half of a day, then salt is needed for crab preservation. But the earlier the crab is eaten, the better, and the thinner the crab is, the less fat it is.

2. Prepare a basin, put in cold water, add some salt, not too salty. If there is pure water, it is the best, there are disinfectants and other ingredients in the tap water, the crabs are raised and killed faster with tap water, and if it is pure water with salt, the survival time is longer. The depth of the water leaves the crab shell exposed.

2. Preservation of travel time: 1. To bring fresh crabs to relatives and friends, you need to use a fresh-keeping box and ice cubes. 2. Add crushed ice to the bottom of the box, put the bundled crabs on the ice, and be sure to tie them up, because the crabs will fight each other and lose their legs if they are not bundled.

Then put one or two more frozen mineral water on the side of the box.

3. Long-term storage: 1. Put the crabs in the pot and cook them or put them on the grate to steam, (steaming is fresher) the hairy crabs should have their belly upwards - otherwise the crab roe will run away; Sea crabs such as barracuda crabs can be boiled in any way. 2. Put the boiled and cooled crab in the refrigerator, and take it out and heat it up when you want to eat it.

Precautions: Do not freeze fresh crabs directly, the crabs will become thinner and thinner, and they will be empty as soon as they are cooked.

Put the crab in the refrigerator to keep it fresh can be stored for about 2-3 days, cover the crab with a wet towel to ensure its humidity, adjust the temperature of the refrigerator to 5 8, and the crab can survive for about 2 3 days. Crabs, belonging to the class molluscs, decapods, are crustaceans, the body is protected by a hard shell, respires by gills, and in terms of taxonomy, it is the same animal as shrimp, lobster, and hermit crab.

Crab. Common crabs include pike crab, open-sea pike crab, blue crab and Chinese mitten crab. The vast majority of species of crabs live in the sea or near the sea, but some inhabit freshwater or land.

Most crabs are omnivorous, some are carnivorous, such as pike crabs, which can prey on fish, shrimp and molluscs, while a few crabs, such as the window crab, scrape or filter feed on algae and organic detritus.

A small number of crabs live and breed entirely in freshwater, mostly under the rocks of mountain streams, and a few crabs, such as ground crabs, can adapt to life on land, burrowing in damp mud holes, and migrating to the sea during the breeding period.

If it is a fresh live crab, it can be stored in the refrigerator for about 1 week.

Sea crabs can be stored in the freezer compartment of the refrigerator, and the effect is better if they can be vacuum frozen. When a crab is dying or after death, the parasitic bacteria in the body can multiply rapidly and spread.

Breaks down proteins and produces histamine. The longer the crab dies, the more histamine accumulates. Histamine causes telangiectasia and bronchoconstriction in people, causing some degree of damage to the kidneys.

Refrigeration time. If you put the crab in the refrigerator and refrigerate it, you can keep the crab alive for about three days. We just need to tie the crabs and control the temperature of the refrigerated layer of the refrigerator between three and six degrees Celsius before covering them with a wet towel.

It should be noted that we can observe whether there are crabs in the refrigerator every day to see if there is a decrease in vitality, we only need to press the crab's eyes or untie the rope to see if its movements are intense and sensitive, and eat the crabs with poor vitality in time.

In addition to keeping the crabs in the refrigerator, we can prepare a bucket that the crabs can't climb out of, then spread the crabs out into it, and then pour water into the bucket that won't cover the crab's body.
