Abstract: There is provided a process for reducing the free fatty acid content of natural oils by contacting the crude natural oil with a solvent to produce an oil product phase substantially depleted in free fatty acids and a free fatty acid rich solvent phase containing the extracted free fatty acids and some of the glycerides, and processing the free fatty acid rich solvent phase with a membrane to recover the glycerides from the solvent phase, comprising the steps of: (a) contacting the crude natural oil with an immiscible solvent; (b) separating the deacidifed natural oil phase from the solvent phase; (c) providing a selectively permeable membrane having a first surface and a second surface; (d) transferring a portion of the solvent and a portion of the free fatty acids and a lesser portion of the glycerides from the first surface to the second surface across the membrane by contacting the free fatty acid rich solvent phase with the first surface, wherein the pressure at the first surface is greater than the press

Abstract: The current invention describes a new process of purifying oils. In particular, the present invention relates to a method which combines treatment with ad- or absorbing agents (AAs) and a membrane-based process for separating the oil from the contaminated AAs. Further, the present invention relates to the use of active carbon and membrane filtration for purifying oil and the use of purified oil as food or feed ingredients.

Abstract: A process for oxidation of oxidizable materials which are dissolved or suspended in a liquid phase. A contactor in the form of a porous membrane is used. The contactor is designed such that an oxidizing phase flows along one surface thereof while the phase to be oxidized flows along another surface. The oxidation is catalyzed by (i) a catalyst material which constitutes the porous membrane or is deposited in or onto a porous membrane support, or (ii) a catalyst material which is supplied to one or both of the feed streams comprising the oxidizing phase and the phase to be oxidized.
