    • A method of the concentration of acidic phospholipids is disclosed, which comprises a first step wherein lecithin originating in a plant is treated with a solvent containing from 85 to 100% by weight of a lower alcohol and then eliminating the solvent fraction containing said lower alcohol to thereby give a phospholipid mixture, and a second step wherein said phospholipid mixture is treated by using an aqueous solution containing 75% by weight or less of ethanol. In the method of the present invention, the water-soluble components contained in the phospholipid mixture obtained in the first step are efficiently removed in the second step. Thus a lipid mixture containing acidic phospholipids at a high concentration can be relatively easily obtained from the lecithin originating in a plant. This lipid mixture is useful as an emulsifier or a taste modifier.
    • 公开了浓缩酸性磷脂的方法,其包括第一步骤,其中源自植物的卵磷脂用含有85至100重量%的低级醇的溶剂处理,然后除去含有所述低级醇的溶剂级分, 从而得到磷脂混合物,第二步是使用含有75重量%以下乙醇的水溶液处理所述磷脂混合物。 在本发明的方法中,在第二步中有效地除去在第一步骤中获得的磷脂混合物中所含的水溶性成分。 因此,从源于植物的卵磷脂可以相对容易地获得含有高浓度酸性磷脂的脂质混合物。 该脂质混合物可用作乳化剂或调味剂。
