Abstract
Abstract A dry carbonation source for preparing a carbonated beverage and a method for preparing the same, and a dry carbonated beverage concentrate are provided. The dry carbonation source is prepared by reducing the particle size of calcium carbonate in presence of an aqueous solution of a carbohydrate to form a colloidal suspension of calcium carbonate in the aqueous carbohydrate solution, and then drying this suspension to provide a solid suspension of finely-divided calcium carbonate dispersed within a matrix of the carbohydrate. This dry carbonation source is employed with other beverage ingredients to provide a dry carbonated beverage concentrate which readily dissolves to provide a carbonated beverage free from sediment.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
70 words
A dry carbonated beverage concentrate for preparing a carbonated beverage comprising: a. a dry carbonation source which comprises a solid suspension of finely-divided calcium carbonate dispersed within a matrix of a water-soluble carbohydrate wherein the calcium carbonate has an average primary particle size of less than about 100 millimicrons and is substantially free from agregates in excess of about 10 microns, b. a dry non-toxic acid, and c. a flavorant.
Claim 2
Dependent Claim
70 words
A dry carbonated beverage concentrate for preparing a carbonated beverage comprising: a. a dry carbonation source which comprises a solid suspension of finely-divided calcium carbonate dispersed within a matrix of a water-soluble carbohydrate wherein the calcium carbonate has an average primary particle size of less than about 100 millimicrons and is substantially free from agregates in excess of about 10 microns, b. a dry non-toxic acid, and c. a flavorant.
Claim 3
Dependent Claim
25 words
A dry carbonated beverage concentrate according to claim 1 wherein the average primary particle size of the calcium carbonate is less than about 40 millimicrons.
Claim 4
Dependent Claim
26 words
A dry carbonation source according to claim 1 wherein the solid suspension is divided into particles having an average diameter of less than about 50 microns.
Claim 5
Dependent Claim
23 words
A dry carbonated beverage concentrate according to claim 1 wherein the calcium carbonate is substantially free from aggregates in excess of 1 micron.
Claim 6
Dependent Claim
15 words
A dry carbonated beverage concentrate according to claim 1 which further comprises: d. a sweetener.
Claim 7
Dependent Claim
24 words
A dry carbonated beverage concentrate according to claim 5 wherein at least a portion of the sweetener is incorporated within the matrix of carbohydrate.
Claim 8
Dependent Claim
14 words
A dry carbonated beverage concentrate according to claim 5 wherein the sweetener comprises sucrose.
Claim 9
Dependent Claim
16 words
A dry carbonated beverage concentrate according to claim 5 wherein the sweetener comprises L-aspartyl-L-phenylalanine methyl ester.
Claim 10
Dependent Claim
17 words
A dry carbonated beverage concentrate according to claim 5 which further comrises: e. a supplemental carbonation source.
Claim 11
Dependent Claim
52 words
A dry carbonated beverage concentrate according to claim 9 wherein the acid is present in an amount of from about 1 to 20% in excess of the amount theoretically required to release all of the carbon dioxide from the calcium carbonate and the supplemental carbonation source into solution upon solvation in water.
Claim 12
Dependent Claim
52 words
A dry carbonated beverage concentrate according to claim 10 wherein the acid is present in an amount of from about 1 to 10% in excess of the amount theoretically required to release all of the carbon dioxide from the calcium carbonate and the supplemental carbonation source into solution upon solvation in water.
Claim 13
Dependent Claim
27 words
A dry carbonated beverage concentrate according to claim 10 wherein the supplemental carbonation source comprises a sodium, potassium or ammonium carbonate or bicarbonate or any combination thereof.
