How to keep blue crabs fresh for a long time: store them in shallow water, store them in the refrigerator, store them at room temperature, and store them in salt water.

1. Maintain and preserve in shallow water

The water level can reach half the height of the blue crab. Add an appropriate amount of salt. The cover should be breathable. It can usually be stored for 7 to 10 days, if conditions permit. Put it in a constant-temperature cold storage and add some small fish and shrimps, and it will live longer.

2. Refrigerator storage

First tie the claws of the blue crab, then put it in a fresh-keeping box, cover it with a wet towel, and then store it directly in the refrigerator for about three days. It won't get bad for up to 5 days, and it won't die.

3. Store at room temperature

Keep the blue crabs tied up and put them in a bucket or basin at home. You can cover the blue crabs with a wet towel or cloth and put them in A cool place in your home. Note that blue crabs cannot be blown by wind or air conditioning, as they may easily lose water and die. This can generally be stored for 1-2 days.

4. Soak and preserve in salt water

After buying the blue crabs, soak them in light salt water for about five minutes, take them out, put the crabs in a bucket, and add water to the bottom of the crab mouth. To avoid being soaked to death, place it in a cool, moist, breathable place, away from wind and sun. You can also store apple cores and other food in it, and it can survive for about a week.

Precautions for eating crabs

1. It is not advisable to eat too much

Even if you are greedy, you must endure it: because crab meat is cold in nature, it is not advisable to eat too much. People with spleen and stomach deficiency should pay special attention to avoid abdominal pain and diarrhea.

2. Do not eat cooked crabs that have been stored for a long time

Stored cooked crabs are easily invaded and contaminated by bacteria, so crabs should be cooked and eaten now rather than stored. In case you can't finish it, the leftovers must be stored in a clean, cool and ventilated place (preferably in the refrigerator), and must be cooked and steamed thoroughly before eating.

3. Do not eat with tea

Do not drink tea when eating crabs and within 1 hour after eating crabs. Because boiling water will dilute gastric acid, and tea will solidify some components of crab, which is not conducive to digestion and absorption, and may also cause abdominal pain and diarrhea.
