Patent ID: 7585538

Claim:
A process for producing mononuclearly filled seamless microcapsules, comprising: a capsule shell of a hardened capsule material based on an acid polysaccharide and a filler material surrounded on all sides by the capsule shell, including an organoleptitic effective amount of a flavor, wherein the mononuclearly filled microcapules are heat stable and/or cook stable and/or deep fry stable and wherein the water portion in the capsule shell is adjusted to a value of ≦50 wt. %, based upon the total mass of the capsule shell, the process comprising the following steps: (a) preparing a liquid organoleptically effective flavor-including filler material for the microcapsules, (b) preparing a solution or dispersion of a hardenable capsule material based on acid polysaccharide, (c) forming discrete droplets of the liquid filler material for the microcapsules and the solution or dispersion of the hardenable capsule shell material, so that the hardenable capsule material surrounds on all sides the liquid filler material in the droplets, (d) hardening the hardenable capsule shell material, so that seamless polysaccharide capsules are formed, which respectively include mononuclearly filled material and are heat stable and/or cooking stable and/or deep fry stable, (e) drying the formed capsule shells, until the water content in the capsule shell reaches a value of ≦50 wt. %, based upon the total mass of the capsule shell, wherein the forming step is performed using a double nozzle system.
