Yes. Black wolfberry is rich in anthocyanins. Anthocyanins have the property of turning red when exposed to acid and blue when exposed to alkali. If the water used to make the soy milk is slightly alkaline, use red dates, wolfberry, black beans, and black sesame seeds in the powdered state, and the color will be green. It will make the juice made from black wolfberry turn blue, and then mixed with the slightly yellow peanut pulp, the color will be green.
