Fractionated vegetable oil

摘要

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.
