Blackcurrant concentrate (Ribes nigrum)

Blackcurrant concentrate is obtained from the berries of Ribes nigrum, a shrub native to northern Europe and central Asia, whose fruits are harvested at peak ripeness and then processed to extract and concentrate the juice. It is widely used as a natural colourant in food supplement formulations, serving as an alternative to synthetic dyes. Blackcurrant is one of the berries richest in polyphenols, particularly anthocyanins, the natural pigments responsible for its deep purple hue. These compounds contribute to protecting cells against oxidative stress. The berry also provides vitamin C and flavonoids, whose antioxidant properties are well documented in scientific literature. In food supplements, blackcurrant concentrate is primarily valued for its natural colouring properties. Its nutritional profile also makes it an ingredient of interest for formulations seeking to combine a colouring function with a supply of plant-based bioactive compounds.
