Abstract: A new method for producing a fractionated vegetable oil from a plant material. The plant material is extracted with a non-polar solvent and the solvent is evaporated giving a crude oil which includes non-polar and polar lipids. The crude oil is mixed with an alcohol at a controlled temperature and a resulting alcoholic phase is separated and evaporated to recover a polar lipid rich fractionated vegetable oil. The invention also refers to the use of the polar lipid rich fractionated vegetable oil as a surface active agent.

Abstract: A galactolipid material from wheat, produced by extraction of crushed wheat grains and subsequent chromatography of the extracted material, and having a content of DGDG of 51.5%, was mixed with the polar solvents, water and glycerol in order to test the swellability. The samples, prepared in glass tubes, were alternately mixed with a rod and centrifugated at room temperature until homogeneous. The samples were inspected as to physical appearance after storing for at least a week at room temperature.Results:20% (w/w) of galactolipid material in water gave a slightly yellow, highly viscous dispersion. Small liposomes could be observed in a polarizing microscope. At higher galactolipid concentrations a stiff gel was formed.10% (w/w) of the same lipid material in anhydrous glycerol resulted in the formation of an opaque, highly viscous gel.

Abstract: The invention relates to a lipophilic carrier preparation having a continuous lipid phase, comprising a polar lipid material in combination with a non-polar lipid, and optionally a polar solvent, wherein the polar lipid material is a galacto-lipid material. The invention also relates to the use of said lipophilic carrier preparation as a carrier for an active substance in a pharmaceutical composition, but also in nutritional, cosmetical and food products, as well as to a pharmaceutical composition.The invention relates to a lipophilic carrier preparation having a continuous lipid phase, comprising a polar lipid material in combination with a non-polar lipid, and optionally a polar solvent, wherein the polar lipid material is a galactolipid material.

Abstract: The invention relates to an oil-in-water emulsion comprising 0.01-50% by weight of the total preparation, preferably 0.1-10%, of a galactolipid material as an emulsifier. The galactolipid material consists of at least 50% digalactosyldiacylglycerols, the remainder being other polar lipids. The said emulsion is suitable as a carrier for one or more active substances in a pharmaceutical composition, but also in nutritional, cosmetical, food and agricultural products.
