Title
(EN) METHOD FOR DELIPIDATING PLANT EXTRACTS
(FR) PROCÉDÉ DE DÉGRAISSAGE D'EXTRAITS VÉGÉTAUX
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.
(FR) La présente invention concerne un procédé de préparation d'extraits végétaux comprenant les étapes suivantes : (i) la préparation d'un extrait soluble à partir (a) de plantes ou de parties de celles-ci et (b) d'un agent d'extraction aqueux, alcoolique ou mixte aqueux-alcoolique, et l'élimination des composants insolubles ; (ii) la concentration de l'extrait jusqu'à une teneur en substance sèche à laquelle les lipides et lipoïdes contenus forment des agrégats en suspension et/ou en émulsion ; (iii) la séparation des agrégats en suspension et/ou en émulsion par microfiltration à partir de l'extrait concentré ; et (iv) l'élimination éventuelle de l'agent d'extraction. L'invention concerne également un extrait et une composition comprenant ledit extrait tel que préparé par ce procédé.
