A method of preparing a delivery system wherein in the core material is a sweetener, flavoring or the like and is protected by a matrix coating which process comprises: (A) forming an agglomerate of the core material in a hydrophobic matrix coating comprising the steps of melting the hydrophobic coating and dispersing the core material uniformly therein; feeding the dispersion into a heat controlled high pressure spray nozzle; atomizing the dispersion under controlled pressure to maintain the particle size between about 200 to about 30 mesh; collecting the congealed, dry spherical-like particles; and (B) coating the agglomerated particles by conducting the particles through a stream of air passing through a zone of atomized droplets of a second hydrophobic material. |
