Abstract
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.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
231 words
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.
Claim 2
Independent Claim
231 words
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.
Claim 3
Dependent Claim
26 words
The method of claim 1 wherein the active ingredient is selected from the group consisting of essential oils, oleo resins, imitation flavors, fragrances and mixtures thereof.
Claim 4
Dependent Claim
16 words
The method of claim 1 wherein the drying in (b) is performed in a drum dryer.
Claim 5
Dependent Claim
34 words
The process of claim 1 wherein coating is from 2.5 to 10% by weight and the delayed release is from 3-10 minutes after initial chewing of a gum containing said delayed release encapsulated flavorant.
Claim 6
Dependent Claim
31 words
The process of claim 1 wherein the milled powder of (c) is treated with an aqueous solution of a cross-linking agent selected from the group consisting of glutaraldehyde and tannic acid.
Claim 7
Dependent Claim
11 words
The process of claim 5 wherein the cross-linking agent is glutaraldehyde.
Claim 8
Dependent Claim

The process of claim 1 wherein the powder of (c) is treated with an aqueous solution of gum arabic to further seal the powder prior to coating with the water insoluble material in step (d).
Claim 9
Dependent Claim
35 words
The process of claim 1 wherein the base powder of (c) is treated with a thin coating of gelatin to further seal the powder prior to coating with the water insoluble material in step (d).
