Dry sea cucumber's bubbles turn yellow.

Hello, my friend, it is normal for foam water in dry sea cucumber to turn yellow, if it is not obviously serious. There are some salt impurities and mucous membranes on dry sea cucumber's body surface, and it is normal for water to change color slightly during foaming. If it is serious, it means that there is something wrong with the quality of dry sea cucumber, which is dyed or has other additives.
