US4259355A — Chewing gum containing flavor composition and fla…

Claim 1

Independent Claim 170 words

A chewing gum comprising particles of a composition consisting essentially of: a. From about 3 up to about 7 parts by weight of a non-confined hydrophobic flavor oil; b. From about 3 up to about 7 parts by weight of a hydrolytically releaseable flavor oil physically entrapped in an edible solid material selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flvor oil; c. From about 0.1 up to about 1 part by weight of a solid suspending agent which is hydroxypropyl cellulose having a molecular weight of from about 50,000 up to about 800,000 and an all-enveloping mass of a chewable gum base within which said particles are substantially uniformly distributed whereby, as the chewing gum is chewed, the flavor is released at high flavor intensity substantially evenly and uniformly over an extended chewing time.

Claim 2

Dependent Claim 170 words

A chewing gum comprising particles of a composition consisting essentially of: a. From about 3 up to about 7 parts by weight of a non-confined hydrophobic flavor oil; b. From about 3 up to about 7 parts by weight of a hydrolytically releaseable flavor oil physically entrapped in an edible solid material selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flvor oil; c. From about 0.1 up to about 1 part by weight of a solid suspending agent which is hydroxypropyl cellulose having a molecular weight of from about 50,000 up to about 800,000 and an all-enveloping mass of a chewable gum base within which said particles are substantially uniformly distributed whereby, as the chewing gum is chewed, the flavor is released at high flavor intensity substantially evenly and uniformly over an extended chewing time.

Claim 3

Dependent Claim 36 words

The chewing gum of claim 1 wherein the non-confined hydrophobic flavor oil is selected from the group consisting of cherry flavor oil, lemon flavor oil, lime flavor oil, orange oil, peppermint oil and oil of wintergreen.

Claim 4

Oil of wintergreen physically entrapped in modified food starch; n. Oil of wintergreen encapsulated in gelatin capsules; o. Flavor oil of wintergreen entrapped in gum acacia; p. Orange oil physically entrapped in modified food starch; q. Orange oil encapsulated in gelatin capsules; r. Orange flavor oil entrapped in gum acacia; s. Cherry flavor oil entrapped in dextrin; t. Lemon oil encapsulated in dextrin; u. Lime flavor oil entrapped in dextrin; v. Peppermint flavor oil entrapped in dextrin; w. Oil of wintergreen entrapped in dextrin; and x. Orange flavor oil entrapped in dextrin.

Claim 5

Dependent Claim 24 words

The chewing gum of claim 1 wherein the composition has additionally added thereto from 0.03 up to 0.07 parts by weight of propylene glycol.

Claim 6

Independent Claim 153 words

The method of preparing a chewing gum comprising: (i) Admixing a. From about 3 up to 7 parts by weight of a non-confined hydrophobic flavor oil; and b. From about 0.1 up to about 1 part by weight of hydroxypropyl cellulose having the molecular weight of from about 50,000 up to about 800,000, thereby forming a first suspension; (ii) Admixing said first suspension with from about 3 up to about 7 parts by weight of hydrolytically releaseable flavor oil physically entrapped in an edible solid material, selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns thereby forming a second suspension, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil; and (iii) Substantially uniformly distributing said second suspension within an all-enveloping mass of a chewable gum base.

Claim 7

Independent Claim 153 words

The method of preparing a chewing gum comprising: (i) Admixing a. From about 3 up to 7 parts by weight of a non-confined hydrophobic flavor oil; and b. From about 0.1 up to about 1 part by weight of hydroxypropyl cellulose having the molecular weight of from about 50,000 up to about 800,000, thereby forming a first suspension; (ii) Admixing said first suspension with from about 3 up to about 7 parts by weight of hydrolytically releaseable flavor oil physically entrapped in an edible solid material, selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch, said solid material having a particle size of from about 5 microns up to about 400 microns thereby forming a second suspension, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil; and (iii) Substantially uniformly distributing said second suspension within an all-enveloping mass of a chewable gum base.

Claim 8

Independent Claim 128 words

The method of preparing chewing gum comprising the steps of: i. Forming an aqueous solution of a solid flavor entrapment material; selected from the group consisting of gelatin, dextrin, gum acacia and modified food starch; ii. Mixing therewith a first portion of a volatile, water immiscible flavoring agent thereby forming an emulsion; iii. Drying said emulsion thereby forming a solid flavoring agent; iv. Admixing a suspension agent therewith which is hydroxypropyl cellulose having a molecular weight of from about 50,000 up to about 800,000 with a second portion of said flavor agent to form a first suspension; v. Admixing said solid flavoring agent with said first suspension thereby forming a second suspension; and vi. Substantially uniformly distributing said second suspension within an all-enveloping mass of chewing gum base.
