Yellow is a normal color. If it is another color, there may be something wrong with Lycium barbarum. In general, the color of water after soaking is light orange. After soaking in water in summer, the light orange color of water is more obvious. If you soak the medlar produced in autumn in water, the light orange color of the water is very weak. However, whether it is summer or autumn, the water is still relatively transparent after soaking, and the bottom of the cup can be seen. Not very muddy and chaotic.

The fading problem will help you popularize science. Lycium barbarum itself contains natural pigments such as carotene and riboflavin, which are soluble in water and precipitate orange when exposed to water. Soak Lycium barbarum in cold water, which is darker than boiling water. The natural pigment in Lycium barbarum is unstable, and hot water has destructive effect, so the color will be light. Of course, we soak it in hot water. You can try again.
