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+13≦≦0.54+44  (1)wherein x is a ratio (% by mass) of saturated fatty acids (Cto C) in raw fatty acids, and y is a clear melting point (° C.) of a polyglycerol ester of fatty acid.
