Extraction Procedure of unsaponifiable fraction contained in oil or Shortening from microorganism comprising stage of transformation of such Oils, alcoholic solvent extraction with at least 5 Carbon Atoms or one or two Oxygen Atoms INSAP fraction； Onificable； and use of HMDS.
The present invention relates to an extraction process of an unsaponifiable fraction contained in an oil or a vegetable butter, in an oil originating from a micro-organism, in a concentrate of oil or butter or of oil originating from a micro-organism, or in a co-product of the refining industry for vegetable oils, such as deodorisation exhaust and distillates of physical refining, or oils originating from micro-organisms, comprising at least: A) a transformation step of said oils, of said butter or said co-product of the refining industry for vegetable oils or oils originating from micro-organisms in hydro-alcoholic solution, especially via a saponification step, and B) an extraction step of the hydro-alcoholic solution in which the fatty fraction is separated from unsaponifiable fraction by liquid/liquid extraction, said process being characterised in that at least the liquid/liquid extraction step of the step B is performed by using a first solvent system comprising a solvent content selected from the solvents comprising at least 5 carbon atoms and one or two oxygen atoms in the form of either ether function, or ketone function, or ester function, of at least 50% in volume relative to the total volume of the first solvent system, as well as fractions obtained by said process.Procedimiento de extracción de una fracción insaponificable contenida en un aceite o una manteca vegetal, en un aceite que procede de un microorganismo, en un concentrado de aceite o de manteca vegetal o de aceite que procede de un microorganismo, o en un co-producto de la industria del refinado de los aceites vegetales, tales como las fugas de desodorizacion y los destilados de refinado físico, o de los aceites que proceden de microorganismos, que comprende una etapa de transformación de dicha materia grasa en solución hidroalcohólica, a través de una etapa de saponificación, y una etapa de extracción de la solución hidroalcohólica en la que la fracción grasa se separa de la fracción insaponi
