Abstract
Abstract The present invention is method and composition for protecting a flavoring ingredient and providing controlled release therefor, especially in a chewing gum composition, which includes a high molecular weight polyvinyl acetate blended with a hydrophobic plasticizer which forms a film with the high molecular weight polyvinyl acetate in the absence of an added solvent therefor. The flavoring, is blended into the encapsulating composition as, for example, by melt blend which can then be cooled to a solid and ground into particulate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
70 words
A chewing gum composition containing a flavoring agent encapsulated in a solvent-free encapsulation composition, wherein the encapsulation composition comprises a blend of high molecular weight polyvinyl acetate having a molecular weight of about 20,000 to about 100,000 MWU and a hydrophobic plasticizer, said polyvinyl acetate and hydrophobic platicizer being present in a ratio of about 5:1 to about 1:5 and wherein said blend is capable of forming an encapsulating film.
Claim 2
Dependent Claim
70 words
A chewing gum composition containing a flavoring agent encapsulated in a solvent-free encapsulation composition, wherein the encapsulation composition comprises a blend of high molecular weight polyvinyl acetate having a molecular weight of about 20,000 to about 100,000 MWU and a hydrophobic plasticizer, said polyvinyl acetate and hydrophobic platicizer being present in a ratio of about 5:1 to about 1:5 and wherein said blend is capable of forming an encapsulating film.
Claim 3
Dependent Claim
43 words
The composition of claim 14 wherein said flavoring agent is selected from the group consisting of spearmint oil cinnamon oil, oil of wintergreen (methylsalicylate), peppermint oil, citrus oil, fruit essences, cinnamyl acetate, cinnamaldehyde, citral diethylacetal, dihyrocarvyl acetate, eugenyl formate, p-methylamisol and mixtures thereof.
Claim 4
Dependent Claim
18 words
The composition of claim 1 wherein said molecular weight is from about 30,000 MWU to about 60,000 MWU.
Claim 5
Dependent Claim
35 words
The composition of claim 1 wherein said hydrophobic plasticizer comprises a mono-, di- or triglyceride or ester derivatives thereof, said plasticizer having a fatty acid chain of from about 16 to about 20 carbon atoms.
Claim 6
Dependent Claim
15 words
The composition of claim 1 wherein the ratio is from about 2:1 to about 1:2.
Claim 7
Dependent Claim
75 words
A chewing gum composition containing an encapsulated active ingredient wherein the encapsulant comprises a blend of polyvinyl acetate and a hydrophobic plasticizer, said polyvinyl acetate having a molecular weight of from about 20,000 MWU to about 100,000 MWU and said hydrophobic plasticizer selected from the group consisting of mono-, di- and triglycerides having a fatty acid chain length of from about 16 to about 22 carbon atoms wherein said active ingredient is a flavoring agent.
Claim 8
Dependent Claim
75 words
A chewing gum composition containing an encapsulated active ingredient wherein the encapsulant comprises a blend of polyvinyl acetate and a hydrophobic plasticizer, said polyvinyl acetate having a molecular weight of from about 20,000 MWU to about 100,000 MWU and said hydrophobic plasticizer selected from the group consisting of mono-, di- and triglycerides having a fatty acid chain length of from about 16 to about 22 carbon atoms wherein said active ingredient is a flavoring agent.
Claim 9
Dependent Claim
49 words
An edible product comprising an encapsulated active ingredient which is protected form moisture deterioration and which exhibits controlled release, wherein said active ingredient is a flavoring agent and said encapsulant is solvent-free and comprises a blend of high molecular weight polyvinyl acetate and hydrophobic plasticizer in an edible matrix.
Claim 10
Dependent Claim
49 words
An edible product comprising an encapsulated active ingredient which is protected form moisture deterioration and which exhibits controlled release, wherein said active ingredient is a flavoring agent and said encapsulant is solvent-free and comprises a blend of high molecular weight polyvinyl acetate and hydrophobic plasticizer in an edible matrix.
