Chokeberry, also referred to as Aronia, is a deciduous shrub belonging to the rose family. It produces black, red, and blue colored berries with very high antioxidant properties. Black chokeberries (Aronia melanocarpa) are regarded for their dark color due to one of the highest anthocyanin contents in plants. The juice, extracted from the fruit, provides red to purple hues in a variety of foods and beverages. Like other anthocyanin sources, the hue shifts from red to purple as pH increases and is most stable in acidic conditions.
