1 Look at the shape of the sea cucumber. If the shape is relatively complete and correct, such a sea cucumber is a good sea cucumber. Generally, if the body is flat and uneven, such a sea cucumber is a bad sea cucumber.

2. Dry sea cucumber, is it dry enough? The price of sea cucumber is relatively expensive, and the lower the water content, the more affordable it is. Therefore, when you buy dry sea cucumber, you'd better choose the one with higher dryness, which is beneficial to the preservation of sea cucumber. Some sea cucumbers that look good are added with white sugar or alum by some merchants, which is not very good, so pay more attention when selecting them.

3. Look at its color. If it is a white sea cucumber, don't buy it. This sea cucumber has a lot of salt and a low nutritional value.
