Abstract
Abstract 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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
124 words
A method of preparing a delivery system wherein the core material is selected from the group consistency of sweeteners, flavorings, and mixtures thereof 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 matrix 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.
Claim 2
Independent Claim
