Abstract
The oil of pips of fruits of the Ribes genus is an abundant, cheap source of .gamma.-linolenic acid. 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, colorings and odorous compounds. The refined oil is a valuable ingredient in cosmetic, dermatological, dietetic and pharmaceutical compositions.
