    • The invention relates to microcapsules comprising one or more active substances embedded in a matrix and comprising a powdering agent, said microcapsule further comprising a component which is the product of the reaction between at least one component in said matrix and at least one component in said powdering agent, and which microcapsule is obtainable by a process which comprises the steps of - providing a solution or dispersion of said matrix, - adding to said solution or dispersion said at least one active substance, - treating the mixture thus obtained to prepare a solution or dispersion of said at least one active substance and said matrix, - finely dividing and drying the solution or dispersion thus obtained to prepare a mass of particles each containing the active substance embedded in the matrix, - adding simultaneously with said finely dividing and drying step said powdering agent, whereby said powdering agent comprises said at least one component, which is able to react with said at least one component in said matrix and that said powdering agent comprising said a least one component is added in dry form, as well as the method itself. The microcapsules of the invention may be used in products, such as foods, food supplements, beverages, pharmaceutical or veterinary products, feeds or feed supplements, personal care products or household products.
