Aronia Juice Powder Processing
The species is Aronia melanocarpa (Michx.) Elliott, family Rosaceae, known as black chokeberry or aronia. The word chokeberry points to the dry, puckering taste, which comes from tannins. Red chokeberry, Aronia arbutifolia, and purple chokeberry are related, and the black fruit is distinguished by its dark skin and juice. Aronia is not related to blueberry, bilberry or elderberry, even though all of them are dark.
The raw material is aronia juice concentrate. The berries are crushed and pressed, and the dark juice is concentrated, mixed with maltodextrin and spray-dried. The carrier keeps the powder free-flowing and soluble and it softens the sharp, astringent edge of the juice a little, although the dry, puckering character of aronia remains clear and is the main reason for using sweeteners or milder fruit powders next to it.
Black chokeberry juice is exceptionally dark. The pigment sits in both the skin and the pulp, which means that the juice powder keeps a high color intensity at low use levels, and this is a practical advantage in products where tint matters.
Aronia is a hardy shrub of cold climates, and the berries are harvested when fully black and slightly soft. Late harvest raises sugar and color, and juice from late fruit is less harsh than from early fruit, although the astringent character never disappears. The fruit is small, with a thin skin and a waxy bloom.
