Crab is a kind of aquatic product, and its freshness will greatly affect its taste. If you put it in the freezer to thaw and cook, the smell of crabs will increase and the meat quality will not be as elastic as when it is fresh. Therefore, I don't recommend that you preserve hairy crabs by freezing. Fresh hairy crabs taste the best.

If you need to store hairy crabs for a long time, you can only put them in the freezer of the refrigerator. Hairy crabs can be stored for 1-2 months in the frozen state. But it should be noted that crabs must be frozen while alive. If the crab dies, you can only throw it away with regret.

Fresh-keeping method of hairy crabs

Crabs belong to fresh aquatic products and can be preserved for a short time after leaving water. You can eat the bought crabs after 3 days, which is relatively simple: choose crabs with strong vitality, tie your feet and pliers to reduce physical exertion, then put them in the freezer of the refrigerator and cover them with wet towels for preservation.

When eating every day, choose the crab with insufficient vitality and let it live. How do you know that crabs have insufficient vitality? The way to tell is to touch the crab's eyes with your hands. If the response is not sensitive, it means that the crab is not alive enough.

First of all, river crabs are also hairy crabs and crustaceans. They live at the bottom of rivers and lakes and are fierce omnivores, so they have strong vitality. If they are tied up and stored at room temperature, they may live for a long time.

But if it is frozen, be sure to pay attention. If you put it in the freezer, it will freeze to death soon. Dead hairy crabs must not be eaten. Because hairy crabs like to eat miscellaneous fish and carrion, bacteria multiply after death, and a lot of oxygen in the body will be decomposed into toxic substances-histamine, which will cause poisoning in nine cases out of ten.

Maybe someone will argue that there are crabs in the north, the temperature is sometimes MINUS 20 degrees, and there are live crabs at the bottom of the river! You don't understand this. Crabs like lobsters like to dig holes. When the temperature drops, they go back to their nests to hibernate.

Therefore, the correct freezing method is to put it in the cold room, and the bought crab can't be washed with water. Keep the heavy, thick and damn rope tied to the crab's leg intact, and then cover it with a wet towel, so it's no problem to live for about a month.
