What are the methods of selecting sea cucumber?

What are the selection methods of sea cucumberLook at the color, black or not; look at the shape, pinch it; add heat, bend it.

1, look at the color, black or not. Good sea cucumbers should be gray-brown or black-brown, with a shiny surface and gray, white intestines. Inferior sea cucumbers laced with sugar are black, dark in color, and the intestines will turn red or black.

2. Look at the shape and pinch it. Good sea cucumbers have a well-proportioned body, firm flesh, sharp and intact thorns, and are hard to the touch and do not bend easily. The opposite is true for sea cucumbers laced with sugar, where the body bends easily and the spines are straight.

3. Add heat and bend it. Sugar dissolves easily, so when you buy sea cucumbers, you can find a way to add heat to the sea cucumber. The easiest thing is to rub your hand hot, then put the sea cucumber in your hand to cover for a while, wait for it to get hot, then grab the two ends of the sea cucumber and let the sea cucumber bend. If you find that the sea cucumber becomes bent and soft, and the higher the temperature, the more obvious this change, it means that it is mixed with sugar.

Active Ingredients of Sea Cucumber:

1, Sea Cucumber Polysaccharide?

Sea cucumber polysaccharide is an important functional component of sea cucumber body wall, and its content can account for up to 31% of the total organic matter of dried sea cucumber. The polysaccharide content and composition of sea cucumber is an important chemical index to measure the nutritional value of sea cucumber.

Modern pharmacological studies have shown that sea cucumber polysaccharides have a variety of pharmacological activities, including anti-tumor, immunomodulation, anti-coagulation and anti-thrombosis, lipid-lowering and other effects. The polysaccharides in the body wall of sea cucumber are mainly classified into two categories: sea cucumber chondroitin sulfate and sea cucumber fucoidan sulfate.

2, sea cucumber saponin?

Sea cucumber saponin is a class of triterpenoid saponin unique to sea cucumber, which is the main secondary metabolite of sea cucumber and the chemical substance basis for its defense. Modern pharmacological activity research shows that sea cucumber saponin has a variety of biological activities such as improving immunity, anti-tumor, anti-bacterial, anti-cancer and so on.

3. Cerebrosides? ?

Cerebrosides, also known as acylsphingosine hexoside, is a class of endogenous bioactive substances widely present in the cell membranes of fungi, plants, animals and marine organisms.

In 1876, Thudichum first pointed out the existence of a compound called cerebrosides in the brain, and subsequent studies have shown that cerebrosides are a kind of sphingolipids, which are composed of two parts: ceramide and glycosyl. In recent years, only more than 10 kinds of cerebroside compounds have been reported in sea cucumber, and they are found to have biological activities such as preventing fatty liver and anti-tumor.
