    摘要： 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 4° 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.

    摘要： Provided is a preparation process of diglycerides which comprises reacting a fatty acid or lower alkyl ester thereof with glycerin in the presence of an immobilized partial glyceride lipase while removing water, which is generated upon reaction, out of the system. The reaction is preferably terminated when the acid value (AV) of the reaction mixture satisfies the following range: 50R-60>AV>70R-150 (with the proviso that AV>0). The present process makes it possible to efficiently prepare a high purity of diglycerides without impairing lipase activity even under reduced pressure. The present process is effective without being influenced by variations in reaction conditions such as fatty acid/glycerin ratio, reaction temperature or enzyme concentration. Particularly, even when the fatty acid/glycerin ratio is high, a high purity of diglycerides can be produced at a high reaction yield.
