Abstract

Procédé pour fabriquer des microcapsules. Ce nouveau procédé comprend la dissolution d'une huile et graisse dans un solvant organique par chauffage, la dispersion d'une matière à enrober dans la solution obtenue, le refroidissement de la dispersion tout en agitant pour produire la coacervation de l'huile et graisse sur la matière à enrober, et la séparation et le séchage du produit particulaire enrobé obtenu. Utilisation de ce procédé pour enrober des additifs alimentaires pour les animaux et pour l'homme, pour enrober des médicaments, des produits chimiques agricoles, etc.
