ABSTRACT:
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.
