Black/Purple Carrot 


D.D. Williamson

Black/Purple Carrot is an anthocyanin that works for colouring in many types of food and beverage applications and are grown mostly in southern Europe and Asia. These pigments exhibit a reversible change in molecular structure as the pH of solutions change from acidic to basic. This change in structure is characterized by a shift in hue from red to purple to blue as the pH changes from acidic to basic. Anthocyanins from purple carrots are more stable over a wider pH range than most anthocyanins making them ideal for yogurts and other dairy products.
