  • Method and apparatus for processing vegetable oil miscella, method for conditioning a polymeric microfiltration membrane, membrane, and lecithin product
    Publication number: 20050118313
    Abstract: A method for processing vegetable oil miscella is provided. The method includes steps of feeding vegetable oil miscella to a conditioned polymeric microfiltration membrane, and recovering a permeate stream having a decreased weight percent of phospholipids compared with the weight percent of phospholipids provided in the miscella. The retentate stream can be further processed for the recovery of lecithin. The polymeric microfiltration membrane can be conditioned for the selective separation of phospholipids in the miscella. A method for conditioning a membrane for selective separation of phospholipids from vegetable oil miscella, and the resulting membrane, are provided. The membrane which can be conditioned can be characterized as having an average pore size of between about 0.1? and about 2?.
