Title (EN) METHOD FOR PRODUCING PICKERING EMULSIONS FROM BIOSOURCED PARTICLES
(FR) PROCÉDÉ DE PRÉPARATION D'ÉMULSIONS DE PICKERING À PARTIR DE PARTICULES BIOSOURCÉES
Abstract:
(EN) The present invention relates to a method for producing a Pickering emulsion, comprising the steps of: a) producing a plant powder of at least one oleaginous species; b) adding said plant powder, either to an aqueous phase to obtain a suspension (S) or to an oil phase to obtain a suspension (S'), followed by incorporating either oil into suspension (S) to obtain an oil-in-water type emulsion, or water into suspension (S') to obtain a water-in-oil type emulsion; and c) stirring the emulsion that was obtained at the end of the previous step.
(FR) La présente invention concerne un procédé de préparation d'une émulsion de Pickering comprenant les étapes suivantes : a) la préparation d'une poudre végétale d'au moins une espèce oléagineuse; b) l'addition de ladite poudre végétale - soit dans une phase aqueuse pour obtenir une suspension (S), - soit dans une phase huileuse pour obtenir une suspension (S'), suivie de l'incorporation - soit d'huile dans la suspension (S) pour obtenir une émulsion de type huile- dans-eau, - soit d'eau dans la suspension (S') pour obtenir une émulsion de type eau- dans-huile; et c) l'agitation de l'émulsion obtenue à l'issue de l'étape précédente.
