Title (EN) METHOD FOR REFINING SQUALENE PRODUCED BY MICROALGAE
(FR) PROCÉDÉ DE RAFFINAGE DU SQUALÈNE PRODUIT PAR MICROALGUES
Abstract: front page image
(EN)The invention relates to a method for preparing a composition that is very rich in squalene produced by fermentation of micro-organisms. The method is characterised in that it comprises a purification step selected from the group including: supercritical CO2 extraction in a multi-stage counter-current fractionation column with extract reflux, and short-path molecular distillation.
(FR)L'invention se rapporte à un procédé de préparation d'une composition à haute richesse en squalène produit par fermentation de microorganismes, caractérisé en ce qu'il comprend une étape de purification choisie dans le groupe constitué de l'extraction par CO2 supercritique sur colonne de fractionnement multiétagée fonctionnant à contre-courant avec reflux d'extrait,et de la distillation moléculaire dite de «court trajet».
