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.

Un nuevo método para producir un aceite vegetal fraccionado de un material de planta. El material de planta se extrae con un solvente no polar y el solvente se evapora que da un petróleo crudo que incluya los lípidos no polares y polares. El petróleo crudo se mezcla con un alcohol en una temperatura controlada y una fase alcohólica que resulta se separa y se evapora para recuperar un aceite vegetal fraccionado rico del lípido polar. La invención también refiere al uso del aceite vegetal fraccionado rico del lípido polar como agente tensoactivo.
