Abstract
Abstract The degree of tooth enamel demineralization occurring due to the consumption of a highly acid, low pH beverage is reduced according to the present invention. This is accomplished by adding to the beverage from 1.0 to 6.0 grams per quart, and preferably from 1.25 to 2.5 grams per quart of tricalcium phosphate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
63 words
A dry mix for forming a low pH beverage with water, wherein each quantity of mix for preparing one quart of beverage comprises: suitably effective amounts of flavoring and coloring, from 0.08 to 0.2 gram equivalents of a food acidulent, sufficient buffering material to achieve a final beverage pH of from 2.5 to 3.5, and from 1 to 6 grams of tricalcium phosphate.
Claim 2
Dependent Claim
63 words
A dry mix for forming a low pH beverage with water, wherein each quantity of mix for preparing one quart of beverage comprises: suitably effective amounts of flavoring and coloring, from 0.08 to 0.2 gram equivalents of a food acidulent, sufficient buffering material to achieve a final beverage pH of from 2.5 to 3.5, and from 1 to 6 grams of tricalcium phosphate.
Claim 3
Dependent Claim
22 words
A dry mix as defined in claim 1 wherein the acidulent is citric, malic or fumaric acid or a combination of these.
Claim 4
Dependent Claim
36 words
A dry mix as defined in claim 2 wherein citric acid is employed at a level of from 0.10 to 0.16 gram equivalents for each amount of dry mix employed to prepare one quart of beverage.
Claim 5
Dependent Claim
36 words
A dry mix as defined in claim 3 wherein the tricalcium phosphate is employed at a level of from 1.25 to 2.5 grams for each amount of dry mix employed to prepare one quart of beverage.
Claim 6
Dependent Claim
43 words
A dry mix as defined in claim 4 wherein the buffer is selected from sodium citrate, potassium citrate and combinations of these, and is employed in an amount sufficient to control the beverage pH to within the range of from 2.8 to 3.3.
Claim 7
Dependent Claim
86 words
In a method for preparing a low pH beverage which would have a normal tendency toward demineralizing tooth enamel, each quart of beverage containing suitably effective amounts of flavoring and coloring, from 0.08 to 0.2 gram equivalents of a food acidulent, and sufficient buffering material to achieve a final beverage pH of from 2.5 to 3.5, the improvement which comprises adding from 1 to 6 grams of tricalcium phosphate to each quart of beverage to thereby reduce the tendency of the beverage toward demineralizing tooth enamel.
Claim 8
Dependent Claim
86 words
In a method for preparing a low pH beverage which would have a normal tendency toward demineralizing tooth enamel, each quart of beverage containing suitably effective amounts of flavoring and coloring, from 0.08 to 0.2 gram equivalents of a food acidulent, and sufficient buffering material to achieve a final beverage pH of from 2.5 to 3.5, the improvement which comprises adding from 1 to 6 grams of tricalcium phosphate to each quart of beverage to thereby reduce the tendency of the beverage toward demineralizing tooth enamel.
Claim 9
Dependent Claim
20 words
A method according to claim 6 wherein the acidulent is citric, malic or fumaric acid or a combination of these.
Claim 10
Dependent Claim
28 words
A method as defined in claim 7 wherein citric acid is employed at a level of from 0.10 to 0.16 gram equivalents for each one quart of beverage.
Claim 11
Dependent Claim
28 words
A method as defined in claim 8 wherein the tricalcium phosphate is employed at a level of from 1.25 to 2.5 grams for each one quart of beverage.
Claim 12
Dependent Claim
43 words
A method as defined in claim 9 wherein the buffer is selected from sodium citrate, potassium citrate and a combination of these, and is employed in an amount sufficient to control the beverage pH to within the range of from 2.8 to 3.3.
