Sea cucumbers are divided into light dry sea cucumber, salt dry sea cucumber, sugar dry sea cucumber and freeze-dried sea cucumbers. At present, dry sea cucumber is the best seller and the highest price in the market. Like some big brand stores, the price of pure dry bottom sowing wild sea cucumber is usually 10,000 yuan, and the price of ordinary light dry sea cucumber is more than 4,000 yuan. Adding salt and sugar to sea cucumber can effectively reduce the cost. Some sea cucumbers with high salt content even have a salt content of over 50%. Generally, the growth rate of this kind of sea cucumber is very low, although the price is affordable, but the cost performance is not high. Generally speaking, most merchants will not process good bottom-sown sea cucumbers into salt dry sea cucumber. Therefore, consumers should not only look at the price, but also consider it comprehensively when purchasing sea cucumbers. The best sea cucumber in China is the wild sea cucumber in Zhangzidao, Dalian at 39 degrees north latitude. It is far from the land, the sea water is pure and pollution-free, and the sea cucumber grows for a long time. Therefore, the produced wild sea cucumber has the best quality, the highest wall thickness and nutritional value, but the yield is quite limited. Only a few big brands such as Fulinmen Sea Cucumber can buy it in China.
