Abstract
Oleaginous material is fractionated into two fractions having different melting points from each other by emulsifying all the oleaginous material with water and using with a surfactant having an HLB value of 5 to 10 as an emulsifier, at a temperature at which all the oleaginous material is substantially melted. The emulsion is cooled to a temperature at which one fraction of the oleaginous material crystallizes so that the emulsion forms a lighter phase containing the other fraction of the oleaginous material and a heavier phase comprising an aqueous phase containing crystals of said first fraction dispersed therein. The lighter phase is separated from the heavier phase and then the crystals of the first fraction are separated from the remainder of the heavier phase.
