It is extracted using solvents from dried and ground residues from the production of juices, preserves and jellies or brandies, liqueurs and schnapps of fruits, such as blackcurrant, redcurrant or gooseberry. According to a preferred embodiment, the residues are treated with ethanol before being extracted with hexane in order to free the oil from most of the free fatty acids, waxes, colourings and odorous compounds.
