A method for separating sterols from neutral substances comprising the sterols, the method comprising: (a) providing a hydrocarbon fraction containing in the neutral substances; (b) optionally washing the hydrocarbon fraction with water; (c) optionally separating the neutral substances from the hydrocarbon; (d) evaporation fractionating the hydrocarbon fraction from step (a) or step (b), or the neutral substances from step (c), to obtain a sterol- rich fraction; (e) dissolving the sterol-rich fraction in a solvent and crystallizing the sterols from the solvent; and (f) separating the obtained sterol crystals from the solvent.

L'invention concerne un procédé de séparation de stérols de substances neutres les contenant, ledit procédé consistant à (a) préparer une fraction d'hydrocarbure contenant les substances neutres; (b) à éventuellement laver à l'eau la fraction d'hydrocarbure; (c) à éventuellement séparer les substances neutres de l'hydrocarbure; (d) à fractionner par évaporation la fraction d'hydrocarbure de l'étape (a) ou (b), ou les substances neutres de l'étape (c), afin d'obtenir une fraction riche en stérols; (e) à dissoudre la fraction riche en stérols dans un solvant et à cristalliser les stérols du solvant; et (f) à séparer du solvant les cristaux de stérol obtenus.
