(EN) CONTINUOUS MULTI-MICROENCAPSULATION PROCESS FOR IMPROVING THE STABILITY AND STORAGE LIFE OF BIOLOGICALLY ACTIVE INGREDIENTS
(ES) PROCESO DE MULTI-MICROENCAPSULACIÓN CONTINUO PARA LA MEJORA DE LA ESTABILIDAD Y ALMACENAMIENTO DE INGREDIENTES BIOLÓGICAMENTE ACTIVOS

Abstract
(EN) The present invention relates to microcapsules and a continuous micro-encapsulation water-in-oil-in-water microencapsulation process through in situ and interfacial polymerisation of the emulsion. The formulation comprises a continuous water phase having a dispersion of microcapsules which contain oil drops and wherein the inside of each oil phase drop - containing optionally oil-soluble materials - there is a dispersion of water, or aqueous extract or water dispersible material or water soluble material. The oil drops are encapsulated with a polymerisable material of natural origin. Such microcapsules are appropriated for spray-dry process, to be used as dry powder, lyophilised, self-emulsiable powder, gel, cream and any liquid form. The active compounds included in the microcapsules are beneficial to the health and other biological purposes. Such formulations are appropriate to be incorporated in any class of food, specially for the production of nutraceuticals, as well as cosmetic products (such as rejuvenescence creams, anti-wrinkle creams, gels, bath and shower consumable products and sprays). The preparations are adequate to stabilise compounds added to food, media for cultivating microbes and nutraceuticals, specially those which are easily degradable or oxidizable.
(ES) La presente invención se refiere a microcápsulas y proceso continuo de microencapsulación agua en aceite en agua mediante una polimerización in-situ a interfacial de la emulsión. La formulación comprende una fase acuosa continua teniendo una dispersión de microcápsulas que contienen gotas de aceite, y en donde en el interior de cada gota de fase aceite-opcionalmente conteniendo materiales solubles en aceite-, existe una dispersión de agua, o extracto acuoso o material dispersable en agua o material soluble en agua. Las gotas de aceite son encapsuladas con un material polimerizable de origen natural. Tales microcápsulas son adecuadas para procesos de secado por spray (spray-dry), para ser usadas como un polvo seco, liofilizadas, polvo autoemulsionable, gel, crema y cualquier forma líquida. Los compuestos activos incluidos en las microcápsulas son beneficiosos para la salud a otros fines biológicos. Tales formulaciones demuestran ser adecuadas para su incorporación en cualquier clase de alimentos, especiahnente para la producción de nutracéuticos, así como productos cosméticos (com cremas rejuvenecedoras, antiarrugas, geles, consumibles de baño y ducha y en sprays.) Las preparaciones son adecuadas para estabilizar compuestos añadidos a los alimentos, medios de cultivo de microbios y nutracéuticos, en especial, aquellos que son fácilmente degradables u oxidables.
(FR) L'invention concerne des microcapsules ainsi qu'un procédé continu de microencapsulage eau-dans huile-dans eau au moyen d'une polymérisation in-situ et interfaciale de l'émulsion. La formulation comprend une phase aqueuse continue ayant une dispersion de microcapsules qui contiennent des gouttes d'huile et où l'on trouve à l'intérieur de chaque goutte de phase huileuse, éventuellement contenant des matériaux solubles dans l'huile, une dispersion d'eau, ou un extrait aqueux ou un matériau dispersible dans l'eau ou un matériau soluble dans l'eau. Les gouttes d'huile sont encapsulées avec un matériau polymérisable d'origine naturelle. De telles microcapsules sont appropriées à des procédés de séchage par spray, peuvent être utilisées comme poudre sèche, lyophilisées, comme poudre auto-émulsionable, gel, crème et toute autre forme liquide. Les composés actifs inclus dans les microcapsules sont bénéfiques à la santé et à d'autres fins biologiques. De telles formulations peuvent être incorporées dans n'importe quel type d'aliment, en particulier dans la production de nutraceutiques ainsi qu'en tant que produits cosmétiques (crème de rejuvénescence, crème anti-rides, gel, produits pour le bain et la douche et en spray). Les préparations sont appropriées à la stabilisation de composés ajoutés aux aliments, des milieux de culture de microbes et des nutraceutiques, en particulier ceux qui sont facilement dégradables ou oxydables.
