Title
(DE) VERFAHREN ZUR DELIPIDIERUNG VON PFLANZENEXTRAKTEN
(EN) METHOD FOR DELIPIDATING PLANT EXTRACTS
(FR) PROCÉDÉ DE DÉLIPIDATION D'EXTRAITS DE PLANTES
Abstract
(EN) The present invention is directed to a method for preparing plant extracts comprising the steps of (i) preparing a soluble extract from (a) plants or parts thereof and (b) an aqueous, alcoholic or aqueous alcoholic mixed extractant; and removal of insoluble components, (ii) concentrating the extract to a dry substance content at which the contained lipids and lipoids form suspended and/or emulgated aggregates, (iii) separating the suspended and/or emulgated aggregates by microfiltration from the concentrated extract, and (iv) optionally removing the extractant. The invention further pertains to an extract and composition comprising said extract as prepared by this method.
