The present invention relates to a process for the production of polar lipid-rich materials and preferably phospholipids. Preferably the polar lipid-rich materials are separated and recovered from de-oiled native raw materials by extraction with water and alcohol and use of density separation to separate the resulting mixture. The invention also includes an improved process for de-oiling the native raw material before extraction and recovery of the polar lipids. La présente invention concerne un procédé de production de matières riches en lipides polaires et, de préférence, en phospholipides. De préférence, on sépare et on récupère les matières riches en lipides polaires précitées à partir de matières premières naturelles déshuilées par extraction avec de l'eau et de l'alcool et on fait appel à une séparation par densité pour séparer le mélange obtenu. L'invention se rapporte également à un procédé amélioré permettant de déshuiler la matière première naturelle avant l'extraction et la récupération des lipides polaires.
