Aronia (Aronia melanocarpa; also known as chokeberry), is a shrub native to North America. Chokeberries can be found in many food products like wine, jams and juices. The deep purple colour of Aronia melanocarpa has attracted a lot of scientific attention. Purple fruits are rich in polyphenols, especially antioxidants known as anthocyanins and proanthocyanidins. These pigments demonstrate potent cell-protective properties. The Oxygen Radical Absorbance Capacity or ORAC (a measure of the antioxidant strength of foods) demonstrates chokeberry to have one of the highest values yet recorded among berries.
