  • Method for the fractionation of oil and polar lipid-containing native raw materials
    Patent number: 7550616
    Abstract: 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.
