Abstract

Process for the recovery from edible oils containing at least 50% linoleic acid combined as glycerides, of a fraction enriched in combined linoleic acid, in which the oil is contacted with an organic polar solvent immiscible therewith, the liquid phases formed being separated and the enriched fraction recovered from the polar solvent. Dialkyl lower amides are preferred polar solvents and sunflower, safflower and cottonseed oil are preferred oils. [US3892789A]
