Black chokeberries (Aronia melanocarpa) are regarded for their dark colour 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.
In 2005, DDW acquired Artemis International’s elderberry and chokeberry (aronia) colouring business. Today, chokeberry (aronia) is one of the many natural colourings we use to colour foods and beverages.
Chokeberry / Aronia Juice
Chokeberry juice anthocyanins are primarily cyanidin 3-galactoside and cyanidin 3-aribinoside, both mono-glycosylated. This mono glycosylation does not contribute to the greatest stability within the anthocyanin colour options.
Like other anthocyanin sources, the hue shifts from red to purple as pH increases and is most stable in acidic conditions.
