PROBLEM TO BE SOLVED: To provide a refined lipid composition reduced in free fatty acids from a lipid composition containing a polar lipid and free fatty acids.SOLUTION: There is provided a method for producing a refined lipid composition containing a polar lipid which comprises the following steps (1) to (4): (1) a step of dissolving a lipid composition containing at least a polar lipid and free fatty acids in a non-polar organic solvent to prepare a lipid-containing liquid (2) a step of bringing a basic aqueous solution into contact with the lipid-containing liquid (3) a step of separating a water layer and precipitates from an organic layer as the lipid-containing liquid and (4) a step of removing the non-polar organic solvent from the organic layer.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】極性脂質と遊離脂肪酸を含有する脂質組成物から、遊離脂肪酸を低減した精製脂質組成物を提供すること。【解決手段】下記工程(1)~(4)を有する、極性脂質を含有する精製脂質組成物の製造方法により解決できる。(1)少なくとも極性脂質と遊離脂肪酸を含有する脂質組成物を、非極性有機溶媒に溶解させて脂質含有液を調製する工程、(2)上記脂質含有液に塩基性水溶液を接触させる工程、(3)脂質含有液である有機層から、水層及び沈殿物を分離する工程、(4)有機層から非極性有機溶媒を除去する工程【選択図】なし
