摘要：
The invention relates to a method for extracting an unsaponifiable fraction contained in an oil or a vegetable butter, in an oil from a microorganism, in a concentrate of oil or vegetable butter or oil from a microorganism, or in a co-product from the plant oil refining industry, such as the deodistillates and the physical refining distillates, or oils from microorganisms, said method comprising at least: A) a step of transforming said oils, said butter or said co-product from the industry of refining vegetable oils or oils from microorganisms in a hydroalcoholic solution, especially via a step of saponification, and B) a step of extracting the hydroalcoholic solution wherein the fatty fraction is separated from the unsaponifiable fraction by a liquid/liquid extraction. Said method is characterised in that at least the step of liquid/liquid extraction of step B is carried out using a first system of solvents 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 an ether function, a ketone function, or an ester function, amounting to at least 50 volume % in relation to the total volume of the first system of solvents, as well as fractions obtained by said method.La présente invention concerne un procédé d'extraction d'une fraction insaponifiable contenue dans une huile ou un beurre végétal, dans une huile provenant d'un micro-organisme, dans un concentrât d'huile ou de beurre végétal ou d'huile provenant d'un micro-organisme, ou dans un co-produit de l'industrie du raffinage des huiles végétales, tel que les échappées de désodorisation et les distillais de raffinage physique, ou des huiles provenant de micro-organismes, comprenant au moins : A) une étape de transformation desdites huiles, dudit beurre ou dudit co-produit de l'industrie du raffinage des huiles végétales ou des huiles provenant de micro-organismes en solution hydro-alcoolique, notamment via une étape de saponificatio
