Abstract
Methods are disclosed for extracting and separating polar lipids, including phospholipids, from materials containing oil, polar lipid, protein, ash, and/or carbohydrate, such as egg yolks and other phospholipid-containing materials. In particular, methods for extracting phospholipids from phospholipid-containing materials through the use of an aliphatic alcohol and control of temperature are disclosed. Using these methods, phospholipids in the aqueous liquid fraction will be efficiently separated and will precipitate readily, and can be subjected to separation for improved purity.
