Appearance
Tea polyphenols, freely soluble in water, ethanol, ethyl acetate and slightly soluble in oils, are white to brown powdery solids or crystals with astringent taste. They are stable under hot or acidic condition in the range of PH 2~7. They are slightly hygroscopic, the PH of their aqueous solution is 3~4. Tea polyphenols are easy to be oxidized and become brown under alkaline condition. Green-black compounds are formed when they meet iron ions.
