A misunderstanding. Or dry sea cucumber's nutrition is good.

Sea cucumber is different from other seafood. Once it leaves the sea water, it will melt quickly, because there is an autolytic enzyme in sea cucumber. Fresh sea cucumbers should be treated as soon as possible after they are caught. Moreover, the annual sea cucumber fishing period is very short, and few people can buy fresh sea cucumbers.

The most important reason is that fresh sea cucumbers are rich in high protein, which is difficult to be digested and absorbed by the human body. It is better to turn them into dry sea cucumber after processing, and dry sea cucumber is more conducive to human absorption after soaking and eating.

Moreover, fresh sea cucumbers are not easy to cook, and they can't master the heat. If they are not cooked, they are easy to have diarrhea. Usually, the sea cucumbers we eat in hotels are all made by the chef soaking dry sea cucumber's hair. Such sea cucumbers have high nutritional value and are beneficial to human absorption.
