Red Currant Juice Powder Processing
The species is Ribes rubrum L., the red currant, a deciduous shrub of the gooseberry family whose translucent red berries ripen in hanging clusters called strigs. It is not the black currant, Ribes nigrum, which is darker, more aromatic and more heavily pigmented, and it is not the Zante currant, a small dried grape. A search for “currant powder” meets all three, so the species decides what the powder actually is.
The raw material is red currant juice concentrate. Pressing leaves the skins and most seeds in the pomace, so the juice carries the acids, sugars and pigments of the berry but little of its fiber. The concentrate is blended with maltodextrin and atomized in a spray dryer, where water leaves in seconds and the dissolved solids set as fine particles. The carrier makes the powder soluble and free-flowing, and it lightens the color and softens the sourness compared with pressed juice. Whole-berry fiber belongs to freeze-dried forms.
Red currants are naturally rich in pectin and acid, which is why the fresh fruit is a classic jelly berry, and some of that character survives in the juice. The powder therefore tends to thicken slightly at high dissolved concentration, a behavior formulators of syrups and glazes should check at their own use level.
