The reason why black wolfberry changes color when soaked in water is because anthocyanins in black wolfberry are soluble in water. Anthocyanin is a water-soluble pigment, which is particularly sensitive to pH value. It can change different colors with the pH of the environment. It is purple (purple, purplish red, iron red, etc.) in acidic water. ) and blue in alkaline water (blue, turquoise, lake blue, etc. ). So black Lycium barbarum soaked in different water is a different color. Generally, mineral water bubbles are purple, and tap water bubbles at home are blue.
Black Lycium barbarum should be soaked in warm water or cold water below 60 degrees, not boiled water, because anthocyanins and some nutrients in black Lycium barbarum are afraid of high temperature. The change of soaking color of Lycium barbarum is generally related to water quality and has little to do with Lycium barbarum. Black Lycium barbarum will appear different blue and purple because of the change of pH and temperature of water.
