Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
A method for improving the solubility and stability of dipeptide nutritive sweetners, while at the same time producing a bulked sweetening composition having a broader spectrum of amino acids which comprises co-drying an aqueous solution of at least one of said sweeteners with a nutritious, bland low molecular weight polypeptide, the sweetener and polypeptide being present in solution at from about equimolar amounts to weight ratios of sweetener to polypeptide of 1:100, which sweetener and polypeptide are present at concentrations at which both are soluble.
Claim 2
Independent Claim
85 words
A method for improving the solubility and stability of dipeptide nutritive sweetners, while at the same time producing a bulked sweetening composition having a broader spectrum of amino acids which comprises co-drying an aqueous solution of at least one of said sweeteners with a nutritious, bland low molecular weight polypeptide, the sweetener and polypeptide being present in solution at from about equimolar amounts to weight ratios of sweetener to polypeptide of 1:100, which sweetener and polypeptide are present at concentrations at which both are soluble.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein the dipeptide is L-aspartyl-L-phenylalanine methyl ester.
Claim 4
Dependent Claim
17 words
The method of claim 1 wherein the low molecular weight polypeptide is an enzymatically hydrolyzed nongelatin protein.
Claim 5
Dependent Claim
13 words
The method of claim 2 wherein the enzymatically hydrolyzed protein is vegetable derived.
Claim 6
Dependent Claim
14 words
The method of claim 3 wherein the vegetable derived hydrolyzed protein is soy isolate.
Claim 7
Dependent Claim
11 words
The method of claim 1 wherein co-drying is by freeze drying.
Claim 8
Dependent Claim
11 words
The method of claim 1 wherein co-drying is by spray drying.
Claim 9
Dependent Claim
18 words
The method of claim 1 wherein the ratio of sweetener to polypeptide is about 1:1 to about 1:20.
Claim 10
Dependent Claim
15 words
The method of claim 8 wherein the ratio of sweetener to polypeptide is about 1:4.
