Process for preparing a time delayed release flavorant and an improved flavored chewing gum composition
First Claim
1. A method for preparing a delayed release solid encapsulated flavorant composition for use in chewable compositions characterized by delayed controlled release of substantially all the active encapsulated flavorant after a significant period of chewing, i.e. after approximately 2-3 minutes or more chewing, comprising the steps of:
- (a) preparing an aqueous emulsion of a flavorant which comprises water distillable components in an at least partially hydrophilic encapsulation material comprising gelatin, a natural gum and plasticizer;
(b) drying said emulsion to produce a uniform solid matrix product having the flavorant containing substantially all of its water distillable components i.e. low boilers within a solid emulsion matrix of said encapsulation material;
(c) milling said dried solid matrix to a particle size of less than 20 mesh to produce solid powder; and
(d) coating said solid power with a water insoluable material selected from the group consisting of polyvinyl acetate, polyvinyl alcohol, zein, high Bloom gelatin having a Bloom of over 100 to 300 and ethylcellulose to produce an encapsulated flavorant having a relatively thin water insoluble coating which delays release of flavorant under chewing and the hydrolytic condition of the mouth for a controlled period of time and yet which will thereafter release substantially all of its original flavor notes at desired flavor levels and over a sustained period of time without having significant amounts of flavorant dissolved in the water insoluble coating material.

Abstract
A method for preparing a controlled, delayed release encapsulated flavorant composition for use in chewable confections prepared by the steps of forming an emulsion of flavoring agent in a partially hydrophilic matrix material comprising gelatin, a natural gum and plasticizer; drying the emulsion to a solid matrix; grinding to a solid base powder; and then coating the base powder with a water insoluble material which will prevent elusion of flavor from the base powder and will not dissolve under the hydrolytic condition of the mouth to give a delayed flavor release and yet which, when chewed, will give a substantial flavor "burst" and sustained flavor release as the hydrophilic base powder matrix is wetted in the mouth. An improved variable flavor chewing gum composition containing a delayed release flavorant of the invention is also disclosed.
