Abstract
Abstract The addition of effective amounts of selected peptides, preferably dipeptides such as L-aspartyl-L-phenyl-alanine methyl ester (aspartame), to dental caries supporting food products reduces the tendency toward the occurrence of dental caries. Also, the addition of these peptides to low pH beverages reduces the tendency toward tooth enamel demineralization as well as dental caries.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
47 words
A method of reducing the demineralization of tooth enamel caused by contacting said enamel with an acid-containing food product which normally fosters tooth enamel demineralization comprising the step of adding to said food product, aspartame in an amount that produces excess sweetness and a sweetness modulating material.
Claim 2
Independent Claim
47 words
A method of reducing the demineralization of tooth enamel caused by contacting said enamel with an acid-containing food product which normally fosters tooth enamel demineralization comprising the step of adding to said food product, aspartame in an amount that produces excess sweetness and a sweetness modulating material.
Claim 3
Dependent Claim
50 words
A method according to claim 1 wherein the food product is a beverage having a pH below 6.0, each quart of beverage containing from 0.015 to 0.15 gram equivalents of an edible food acid selected from the group of acids consisting of citric, malic, adipic, fumaric, ascorbic and combinations thereof.
Claim 4
Dependent Claim
23 words
A method according to claim 2 wherein sucrose is employed at a level from about 25 to 100 grams per quart of beverage.
Claim 5
Dependent Claim
33 words
The method according to claim 2 wherein the amount of aspartame is from about 0.25 to about 2.0 grams per quart of beverage or an amount of dry mix for preparing said beverage.
Claim 6
Dependent Claim
48 words
The method according to claim 1 wherein aspartame is used in combination with sweeteners selected from the group consisting of natural sweeteners, synthetic sweeteners and combinations thereof the level of sweetness is reduced by adding a sweetness modulating material selected from the group consisting of alum and naringin.
Claim 7
Dependent Claim
12 words
The method according to claim 5 wherein the natural sweetener is sucrose.
Claim 8
Dependent Claim
24 words
The method according to claim 6 wherein from about 0.1 to about 10.0 parts of aspartame is used for each 100 parts of sucrose.
