ABSTRACT:
Separation of an edible oil into liquid and solid fractions. The edible oil is dissolved in about 0.5-4 parts by weight of a solvent being a C.sub.2 -C.sub.3 alkanol containing about 2 to 10% by weight of water and the solution is cooled to a temperature at which it separates into two liquid phases and a solid fraction crystallizes. The crystallized solid fraction floats in the upper liquid phase and is recovered therefrom. The liquid fraction of the oil is recovered from the lower liquid phase.
