Suggest buying dry sea cucumber. I have tried instant sea cucumber for a while, although it is simple and quick without soaking. However, ready-to-eat sea cucumbers are used for stewing soup. As a result, the sea cucumber was stewed for half an hour and then rotted into dregs. An hour later, it disappeared. Later, I switched back to wild dry sea cucumber. Why wild dry sea cucumber? Because wild dry sea cucumber meat is more compact, more elastic, more resistant to stewing, and the stewed soup is more delicious, I usually choose fresh wild dry sea cucumber sea cucumber with the best nutrition and taste. Fresh sea cucumbers are fished out directly from the sea. It has not been artificially processed and no additives have been added. Nutrition will not be lost, and the original flavor of fresh ginseng will be completely retained. 1. From the technological point of view, dry sea cucumber is made of fresh sea cucumber by processing and drying. It is pure dry sea cucumber, and no substance is added during processing, which will cause less nutritional damage to fresh sea cucumbers. Salt dry sea cucumber will be added with a certain amount of salt during processing to increase the weight and prolong the storage time. 2. From the nutritional point of view, both dry sea cucumber and instant sea cucumber are processed from fresh sea cucumber. Although the nutritional value of these two kinds of sea cucumbers is not as good as that of fresh sea cucumbers, their components are more easily absorbed by the human body than fresh sea cucumbers. But the difference is that in the process of transportation, ready-to-eat sea cucumbers need to be transported and frozen, while the requirements in dry sea cucumber are not high. 3. From the edible point of view, dry sea cucumber needs to go through many procedures before it can be eaten. Instant sea cucumber is simple, fast and convenient to eat. It's easy to tell whether dry sea cucumber is good or bad, but it's relatively difficult to eat sea cucumber.
