Crabs that can't be eaten can also be kept in the refrigerator, but unlike other ingredients, they can't be put directly in. We need to tie crabs firmly to prevent them from wasting energy and "losing weight", and then put them in plates or other containers. Then we prepare a towel, soak it and cover it on the crab. Just adjust the temperature of the refrigerator to about 5-8 degrees.
Although this method can keep crabs fresh, it is not suitable for long-term storage, and it is best to eat them within 1-2 days. It should be noted that the towel should be kept moist, and the crab should not be dehydrated to death in the low-temperature refrigerator.
Foam box preservation method
This method is similar to the principle of refrigerator. The refrigerator suitable for home use is full of ingredients, so when we buy some frozen foods, we usually pack them in foam boxes. At this time, we can leave it and save the crab. It can come in handy.
We also need to tie the crabs firmly. The foam box needs to be frozen in advance, maintained at a low temperature, and then the crabs are placed in the foam box. At the top of the foam box, we can put a wet towel or soaked thatch to keep the humidity and keep the internal temperature low. Then we need to put the foam box in a cool place to avoid direct sunlight. This method can preserve crabs for 2-3 days, but we need to check whether the internal ice pack melts every few hours and replace it in time.
