red cabbage

Red Cabbage

Red cabbage juice is extracted from the red cabbage, Brassica oleracea. This cruciferous vegetable is grown mainly in northern Europe and Asia. 

Anthocyanin colourants 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.
