    • A process for producing egg yolk lecithin containing a reduced amount of PE (phosphatidylethanolamine) and/or containing substantially no impurities. The process comprises dissolving starting yolk lecithin in a polar solvent or a mixture of a polar solvent and a non-polar solvent, and bringing the resulting solution into contact with an ion-exchange resin to thereby selectively adsorb impurities mainly comprising inorganic salts and free amino acids contained in the starting material and substantially exclusively PE among various lipid components efficiently. This process makes it possible to obtain egg yolk lecithin which is substantially free from impurities and which contains a little or scarcely any PE in a high yield on an industrial scale. In practicing this process, the amount of the ion-exchange resin may be so controlled that the obtained egg yolk lecithin contains substantially no impurities while keeping an initial PE level.
