    摘要： This invention provides a process for producing egg yolk lecithin having reduced PE (phosphatidylethanolamine) content and/or containing substantially no impurities. The characteristic features of the invention are that it has ensured the production of egg yolk lecithin containing substantially no impurities while having a low PE content or containing substantially no PE in a high yield on a commercial scale by dissolving the starting-material egg yolk lecithin in a polar solvent or a mixture of a polar solvent and a non-polar solvent and thereafter contacting the resultant solution with an ion exchange resin to thereby cause the resin to selectively and efficiently adsorb and remove impurities predominantly comprising inorganic salts and free amino acids derived from the starting material and substantially only PE in the lipid components therein, and also the production of egg yolk lecithin containing substantially no impurties while retaining the PE content substantially at the initial level from the starting-material egg yolk lecithin on a commercial scale by controlling the quantity of the ion exchange resin to be used in the practice of the above process.

    摘要： Disclosed is an egg yolk phospholipid composition comprising 80% or less of the composition of phospholipids and 0.10% by weight or less of glucose on the basis of the phospholipids. Such an egg yolk phospholipid composition scarcely undergoes browning during the preservation thereof although the phospholipids purity of the composition is not so high, that is, the phospholipids content of the composition is only 80% or less.
