Abstract
Abstract A sugarless chewing gum is provided wherein xylitol is employed as bulk filler and sweetener, and a hydrocolloid, such as xanthan gum or various alginates derived from giant kelp, is employed as a binder between the gum base and xylitol and as a humectant to facilitate retention of moisture in the gum.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
78 words
A sugarless chewing gum in the form of a soft, moist, continuous cohesive gum, which comprises gum base, xylitol as a bulk filler and sweetener, and a hydrocolloid selected from the group consisting of xanthan gum or an alginate derivative of kelp as a binder to facilitate formation of the soft, moist, continuous cohesive gum, said hydrocolloid being present in an amount within the range of from about 0.03 to about 1.0% by weight of said chewing gum.
Claim 2
Dependent Claim
78 words
A sugarless chewing gum in the form of a soft, moist, continuous cohesive gum, which comprises gum base, xylitol as a bulk filler and sweetener, and a hydrocolloid selected from the group consisting of xanthan gum or an alginate derivative of kelp as a binder to facilitate formation of the soft, moist, continuous cohesive gum, said hydrocolloid being present in an amount within the range of from about 0.03 to about 1.0% by weight of said chewing gum.
Claim 3
Dependent Claim
29 words
The sugarless chewing gum as defined in claim 1 wherein said xylitol is present in an amount within the range of from about 50 to about 70% by weight.
Claim 4
Dependent Claim
32 words
The sugarless chewing gum as defined in claim 2 wherein the xylitol is present in a weight ratio to the hydrocolloid of within the range of from about 60:1 to about 2000:1.
Claim 5
Dependent Claim

Claim 10
Dependent Claim
34 words
The sugarless chewing gum as defined in claim 8 wherein said alginate derivative is selected from the group consisting of calcium-sodium alginates, sodium alginates, ammonium alginate, potassium alginates, propylene glycol alginates and mixtures thereof.
Claim 11
Dependent Claim
16 words
The sugarless chewing gum as defined in claim 8 wherein said alginate derivative is calcium-sodium alginate.
Claim 12
Dependent Claim
44 words
A method of preparing the sugarless chewing gum as defined in claim 1, which comprises melting the gum base, adding the hydrocolloid and xylitol to the melted gum base with mixing to form a continuous gum mass, and cooling to form a chewing gum.
Claim 13
Dependent Claim
13 words
The method as defined in claim 11 wherein said hydrocolloid is xanthan gum.
Claim 14
Dependent Claim
