Methods are disclosed for extracting and separating polar lipids, including phospholipids, from materials containing oil, polar lipids, protein, ash, and/or carbohydrate, such as egg yolks and other phospholipid-containing materials as depicted in Figure (1). 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.
L'invention concerne des procédés pour l'extraction et la séparation de lipides polaires, y compris des phospholipides, à partir de matériaux contenant huile, lipide polaire, protéine, cendre, et/ou hydrate de carbone, du type jaune d'oeuf et autres matériaux contenant des phospholipides. L'invention concerne en particulier des procédés pour l'extraction de phospholipides à partir de matériaux contenant des phospholipides par l'utilisation d'alcool aliphatique et le contrôle de la température. Les procédés décrits permettent de séparer efficacement les phospholipides dans la fraction liquide aqueuse et d'en assurer aisément la précipitation, avec possibilité de séparation visant à améliorer la pureté.
