A process, comprising: (a) mixing a fatty acid oil mixture, comprising vitamin E components, with an immiscible organic solvent to form a heterogeneous, two-phase mixture; (b) separating the resulting two-phase mixture to provide a first phase comprising mainly the fatty acid oil fraction and a second phase comprising the organic solvent, vitamin E components and optionally at least one impurity; (c) passing the second phase obtained in (b) across at least one selective membrane, wherein a retentate forms comprising the main amount of the desired vitamin E components from the second phase, and a permeate forms comprising the solvent and any component that is not retained by the membrane, preferably at least one impurity component; (d) removing the organic solvent from the retentate obtained in step (c) to provide as product 1 a composition enriched in at least one vitamin E component, preferably enriched in tocotrienol, compared to the crude oil mixture, (e) optionally removing the organic solvent from the permeate obtained in step (c) to form as product 3 an impurity composition, wherein removal of the solvent is preferably followed by reusing the recovered organic solvent, preferably in step (a), and (f) optionally separating the solvent from the first phase obtained in step (b) to obtain as product 2 a fatty acid oil mixture depleted in vitamin E components compared to the raw material; wherein separation of the solvent from the first phase is preferably followed by reusing the recovered organic solvent, preferably in step (a); wherein the fatty acid oil mixture comprises triglyceride oils, phospholipid oils, and any combination thereof; and wherein the membrane used in step (c) is characterized by a rejection R Vit of the target vitamin E components, preferably the tocotrienol compounds, which is greater than the membrane rejection of the at least one impurity species R Imp.
