1/1 Abstract "Liquid / liquid extraction with a solvent comprising at least 5 carbon atoms and 1 or 2 oxygen atoms" The present invention relates to a process for extracting an unsaponifiable fraction contained in a vegetable oil or butter , in an oil from a microorganism, in a vegetable oil or butter concentrate, or in an oil from a microorganism, or in a by-product of the vegetable oil refining industry, such as deodorization leaks and refining distillates or oils from microorganisms, comprising at least: (a) a step of processing said oils, said butter or by-product from the refining industry of vegetable oils or oils from microorganisms in water-alcohol solution , notably via a saponification step and b) a hydro-alcoholic solution extraction step in which the grease fraction is separated from the inorganic fraction. saponifiable by a liquid / liquid extraction, said process being characterized in that at least the liquid / liquid extraction step of step b is carried out using a first solvent system comprising a solvent content chosen from at least 5 solvents. carbon atoms and one or two oxygen atoms in the form of either ether, ketone or ester functions of at least 50% by volume of the total volume of the first solvent system and the fractions obtained by that procedure.1/1 resumo “extração líquido/líquido com um solvente compreendendo pelo menos 5 átomos de carbono e 1 ou 2 átomos de oxigênio” a presente invenção refere-se a um processo de extração de uma fração insaponificável contida em um óleo ou uma manteiga vegetal, em um óleo proveniente de um microorganismo, em concentrado de óleo ou de manteiga vegetal ou de um óleo proveniente de um microorganismo, ou em um co-produto da indústria de refino dos óleos vegetais, como as fugas de desodorização e os destilados de refino físico, ou os óleos provenientes de microorganismos, compreendendo pelo menos: a) uma etapa de transformação dos referidos óleos, da referida manteiga ou do referido co-produto da indústria
