1, artificial sea cucumber is also called "plain ginseng". The most common manufacturing method is to make it with seaweed powder and glue. This kind of sea cucumber is usually made by mould, with evenly distributed spines, almost the same length, and arranged neatly.

2. The elasticity of artificial sea cucumber is very poor, and the surface will be damaged. When the ginseng is touched, it will fall off easily, and the surface of real sea cucumber is not easy to be damaged and has no defects.

3. There are no openings at both ends of the artificial sea cucumber, and the inner wall is smooth. When the viscera of real sea cucumber is removed, there are still sea cucumber tendons left on the inner wall. Although artificial sea cucumber also says that the viscera has been removed, it is not normal to have no tendons. This is the most direct way to distinguish between true and false sea cucumbers.
