Cranberry Juice Powder Processing
The species is Vaccinium macrocarpon Aiton, family Ericaceae, the American or large cranberry, a close relative of the blueberry. Several other plants are sold as cranberry. The small cranberry, Vaccinium oxycoccos, is a northern wild species, and the lingonberry or cowberry, Vaccinium vitis-idaea, is called cranberry in some regions. Blueberry and bilberry belong to the same genus but have a different flavor and pigment profile, and the species name defines which fruit is used.
The raw material is cranberry juice concentrate. Pressed cranberry juice is concentrated, blended with maltodextrin and then dried in a spray tower to a fine powder. The carrier is important for this fruit, because cranberry juice is extremely acidic and its solids are sticky, so the maltodextrin supports a free-flowing powder and softens the sharpest edge of the acidity.
Cranberries are harvested in autumn, and some are gathered from flooded beds, where the berries float because of the air pockets inside them. Color and acid depend on cultivar, ripeness and year, and the highest red color develops in cool autumn weather, so lots differ in depth of color and in tartness.
Cranberries grow on low vines in sandy, acidic bogs and are harvested once a year. The fruit is firm and keeps well, which makes it easy to freeze and press out of season, and juice from frozen or fresh fruit gives a similar dry powder.
