The Butterfly Pea Powder is made from Natural Butterfly Pea Flower. It is one of the best natural blue pigments for beverages and food. One of the most distinctive characteristics of butterfly pea flowers is that it will change colour when the pH balance changes. This powder is PH sensitive and reacts to acidic liquids such as lemon or lime by changing colour from blue to pink. If you’re all about the base, mix this with base (alkali) ingredients and watch it turn from blue to the coolest shades of green.
