Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
125 words
A flavored chewing gum having a prolonged sweet taste comprising gum base, and an ester gum, and from about 0.02 to about 15% by weight of artificial sweetener, based on the weight of the gum base component, interdispersed in the gum base, said chewing gum being prepared by the process which comprises the steps of incorporating the artificial sweetener in the ester gum prior to incorporating the ester gum in the gum base, combining the resulting combination with gum base ingredients to form a gum base, and mixing the gum base with one or more flavors and sweeteners to form a chewing gum, said ester gum providing a protective shield for the artificial sweetener to control release of said artificial sweetener from the gum base.
Claim 2
Dependent Claim
125 words
A flavored chewing gum having a prolonged sweet taste comprising gum base, and an ester gum, and from about 0.02 to about 15% by weight of artificial sweetener, based on the weight of the gum base component, interdispersed in the gum base, said chewing gum being prepared by the process which comprises the steps of incorporating the artificial sweetener in the ester gum prior to incorporating the ester gum in the gum base, combining the resulting combination with gum base ingredients to form a gum base, and mixing the gum base with one or more flavors and sweeteners to form a chewing gum, said ester gum providing a protective shield for the artificial sweetener to control release of said artificial sweetener from the gum base.

Claim 6
Dependent Claim
17 words
The flavored chewing gum as defined in claim 1 wherein said artificial sweetener comprises free saccharin acid.
Claim 7
Dependent Claim
21 words
The flavored chewing gum as defined in claim 1 wherein said artificial sweetener comprises sodium saccharin, calcium saccharin or ammonium saccharin.
Claim 8
Dependent Claim
34 words
The flavored chewing gum as defined in claim 1 wherein said artificial sweetener is present in an amount within the range of from about 0.002 to about 4.5% by weight of the chewing gum.
Claim 9
Dependent Claim
35 words
The flavored chewing gum as defined in claim 1 wherein the artificial sweetener is present in an amount within the range of from about 0.5 to about 50% by weight of the ester gum component.
Claim 10
Dependent Claim
34 words
The flavored chewing gum as defined in claim 1 wherein the artificial sweetener is present in an amount within the range of from about 0.02 to about 15% by weight of the gum base.
Claim 11
Dependent Claim
25 words
The flavored chewing gum as defined in claim 1 wherein the artificial sweetener has good water-solubility and the ester gum is of relatively low viscosity.
Claim 12
Dependent Claim
25 words
The flavored chewing gum as defined in claim 1 wherein the artificial sweetener has poor water-solubility and the ester gum is of relatively high viscosity.
Claim 13
Dependent Claim
25 words
The flavored chewing gum in accordance with claim 1 wherein said gum base includes, in addition, a food acid incorporated in the ester gum component.
Claim 14
Dependent Claim
41 words
The chewing gum as defined in claim 12 wherein said food acid is selected from the group consisting of fumaric acid, adipic acid, succinic acid, citric acid, malic acid, ascorbic acid, tartaric acid or mixtures of any two or more thereof.
Claim 15
Dependent Claim
20 words
