The nutritional value of large sea cucumber is not necessarily higher than that of small sea cucumber, but its shape mainly depends on the variety, the time of growth and maturity, the growing sea area and its ecological environment, and the technological process of sea cucumber processing. In addition, the storage, soaking and cooking methods of sea cucumber will also affect the nutritional value of sea cucumber.

As a good tonic, sea cucumber contains many elements needed by human body, and it is a food with high protein, low fat and low sugar. Proper consumption will not bring too much metabolic burden to the body. Merchants selling sea cucumbers in the market will distinguish the price of sea cucumbers according to their size. Some merchants advocate that small sea cucumbers are wild sea cucumbers, so the nutritional value is higher, while others advocate that large sea cucumbers have higher nutritional value. It is one-sided to judge the nutritional value of sea cucumber simply by its size.

Introduction of sea cucumber

Sea cucumber is one of the "eight treasures" in all kinds of delicious food. Over the past half century, scholars at home and abroad have studied more than 40 chemical constituents of sea cucumber. The results show that sea cucumber is not only rich in more than 50 nutrients needed by human body, such as amino acids, vitamins and chemical elements, but also contains many bioactive substances such as acidic mucopolysaccharides, saponins and collagen, and its pharmacological activities are very extensive.

The shape of sea cucumber tentacles is an important basis for classification, and dendritic tentacles are found in cladocera sea cucumbers. Shield tentacles are found in cladocera and finfoot sea cucumbers, feather tentacles are found in Anpoda sea cucumbers, and finger tentacles are found in bubble-footed sea cucumbers. The number of tentacles of sea cucumber is often 10, 15, 20, 25 or 30, which are usually multiples of 5.
