Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A process for producing a low calorie sweetening composition which is readily soluble in aqueous systems, low in hygroscopicity and devoid of any aftertaste which alters the sweetness thereof which comprises: a. forming an aqueous solution of glucose; b. heating the glucose solution until the glucose is completely solubilized; c. adding a catalytic amount of phosphoric acid to the heated solution in order to catalyze the polymerization of the glucose; d. evaporating the heated solution to form an acidified glucose syrup; e. vacuum heating the acidified glucose solution to obtain a polyglucose residue; f. forming an aqueous solution of dipeptide sweetener with the polyglucose in a respective weight ratio range of about 1:19 to about 3:7. g. drying the dipeptide sweetener/polyglucose solution.
Claim 2
Dependent Claim
122 words
A process for producing a low calorie sweetening composition which is readily soluble in aqueous systems, low in hygroscopicity and devoid of any aftertaste which alters the sweetness thereof which comprises: a. forming an aqueous solution of glucose; b. heating the glucose solution until the glucose is completely solubilized; c. adding a catalytic amount of phosphoric acid to the heated solution in order to catalyze the polymerization of the glucose; d. evaporating the heated solution to form an acidified glucose syrup; e. vacuum heating the acidified glucose solution to obtain a polyglucose residue; f. forming an aqueous solution of dipeptide sweetener with the polyglucose in a respective weight ratio range of about 1:19 to about 3:7. g. drying the dipeptide sweetener/polyglucose solution.
Claim 3
Dependent Claim
12 words
The process of claim 1 wherein the dipeptide is L-aspartyl-L-phenylalanine methyl ester.
Claim 4
Dependent Claim
27 words
The process of claim 2 wherein the catalytic amount of phosphoric acid is added to bring the solution to a pH of about 1.8 to about 2.4.
Claim 5
Dependent Claim
21 words
The process of claim 2 wherein the polyglucose residue is dissolved in water and neutralized prior to combining with the dipeptide.
Claim 6
Dependent Claim
12 words
The process of claim 3 wherein the neutralized polyglucose solution is ultrafiltrated.
Claim 7
Dependent Claim
24 words
The process of claim 1 wherein the dipeptide sweetener and polyglucose are in the respective weight ratio range of about 1:3 to about 1:4.
Claim 8
Dependent Claim
11 words
The process of claim 1 wherein the dipeptide sweetener/polyglucose is freeze-dried.
Claim 9
Dependent Claim
22 words
The process of claim 1 wherein the dipeptide sweetener/polyglucose solution is dried to a final moisture content of no higher than 10%.
Claim 10
Dependent Claim
9 words
The product of the process according to claim 1.
