Before sea cucumbers are processed and eaten, the first step that must be done is to soak and boil them, because most of the sea cucumbers sold on the market are dried. We can see that the water of sea cucumbers after soaking has a color. Generally, it is green or yellow. If it is green, it means that you have bought a sea cucumber of good quality. So why does the water in which sea cucumbers are soaked turn green? Is it normal for the water in which sea cucumbers are soaked to turn green?

This is normal. The water used for soaking sea cucumbers is usually green or yellow, and the water in China is generally green. Usually, the yellow color of the soaking water indicates that the sea cucumbers are not wild-raised. Only sea cucumbers that have grown in the sea for a long time and feed on kelp, etc. will appear green. If they are raised in a greenhouse, they are usually fed feed, so the water produced will be slightly yellow.

There is also a kind of sea cucumber from Hokkaido, Japan. The water when soaked is red. Therefore, except for green, yellow and red sea cucumbers, other colors are abnormal. Why does the water turn green when boiled with light dried sea cucumber?

This is normal. It means that the sea cucumber grows by eating kelp, seaweed and other green algae plants. It is usually sea cucumber wild-cultured in seawater.

This is usually the case with larger sea cucumbers; smaller sea cucumbers usually do not turn green. This is because large sea cucumbers have grown for a long time. In the ocean, algae will adhere to the outside of the sea cucumbers. The main food of sea cucumbers is green algae, so a large amount of green pigment will remain inside and outside the body, so the water used for soaking will turn green. .

This is also related to the growth environment of sea cucumbers and the food they eat, so some sea cucumbers will have other colors after soaking, such as yellowing or redness. If the soaking water is green, the sea cucumbers are generally of good quality. How to handle fresh sea cucumber
