The invention relates to a method for extracting non disinfecting parts from a communist substance in the refining industry of vegetable oil, vegetable microbial oil, vegetable butter or vegetable oil, such as deodorizing exhaust gas. At least including: (a) a step of converting the oil, the butter or the Communists from the vegetable oil or the microbial oil refining industry into an aqueous alcohol solution, in particular by a step selected from saponification and esterification,(b) The step of extracting from an aqueous alcohol solution in which the fat portion is separated from the irresistible portion by liquid / liquid extraction, (c) the step of optionally purifying the irresistible portion from the crystalline and liquid / liquid extraction groups, The method comprises liquid / liquid extraction of step B, crystallization of step C, and at least one step of liquid / liquid extraction of step C, using a first solvent system including a solvent content selected from a fluorinated aromatic solvent.Especially BTF and BHF,Tert butyl ether, especially 2-ethoxy-2-methylpropane, also known as ethyl tert butyl ether ("ETBE"),Solvents containing at least one silicon atom, in particular l'hexamethyldisilane ("HMDS") and tetramethylsilane ("TMS"),MethyltetrahydrofuranCompared with the total volume of the solvent system, their mixture is ± 50% by volume, the components obtained by the method and the composition containing the components.La présente invention concerne un procédé d'extraction d'une fraction insaponifiable contenue dans une huile végétale,une huile provenant d'un micro-organisme ou un beurre végétal ou dans un co-produit de l'industrie du raffinage des huiles végétales, tel que les échappées de désodorisation, comprenant au moins : A) une étape de transformation de lesdites 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 étap
