Fuente: WIPO "tomato" The present invention relates to a process for preparing a core-shell microcapsule comprising the steps of: (a) mixing a hydrophobic phase comprising a hydrophobic material, preferably a perfume oil or a flavor oil, and an aqueous phase comprising a first polyelectrolyte and, optionally, a second polyelectrolyte having an opposite net charge to the first polyelectrolyte, to form an oil-in-water emulsion, (b) adding an enzyme, preferably an oxidoreductase to the mixture of step (a), optionally, adding a or said second polyelectrolyte having an opposite net charge to the first polyelectrolyte, and (c) providing conditions sufficient to induce crosslinking to the mixture of step (b) by the oxidoreductase to form a core-shell microcapsule as well as to the microcapsules obtained by said process their use and consumer products thereof.
