Abstract: The present invention provides a method for separating a saturated fatty acid and an unsaturated fatty acid from a mixture of fatty acids by a dry fractionation process with a superior efficiency. Namely, the present invention provides a method for producing a saturated fatty acid or an unsaturated fatty acid comprising a dry fractionation process to fractionate a saturated fatty acid and an unsaturated fatty acid in a raw fatty acids mixture by adding a polyglycerol ester of fatty acid to the raw fatty acids mixture, wherein the polyglycerol ester of fatty acid has a clear melting point (y) satisfying the following formula (1):0.38 xnull13nullynull0.54 xnull44nullnull(1)wherein x is a ratio (% by mass) of saturated fatty acids (C12 to C22) in raw fatty acids, and y is a clear melting point (null C.) of a polyglycerol ester of fatty acid.

Abstract: The present invention provides a method for producing a saturated fatty acid and an unsaturated fatty acid, which comprises adding and mixing a polyglycerol ester of a fatty acid to a raw fatty acids mixture, cooling the resultant mixture to deposit crystals, and fractionating the saturated fatty acid and the unsaturated fatty acid, wherein a cooling procedure is performed at a cooling rate of 4null C./h or less when a supersaturation ratio is 60% or more and said cooling rate is varied during the cooling, and a glycerides mixture obtained from the fractionated unsaturated fatty acids. According to the present invention, a saturated fatty acid and an unsaturated fatty acid in a raw fatty acids mixture can be separated easily and efficiently by a dry fractionation process.

Abstract: A process for fractionating an oil composition containing at least 50% by weight of partial diglycerides into a solid portion and a liquid portion, which includes dissolving an emulsifier in the oil composition, cooling the solution to deposit crystals and then conducting solid-liquid separation. The process permits easily fractionating the oil composition into a solid oil composition and a liquid oil composition.
