Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
44 words
A concentrated liquid low calorie sweetening composition comprising a mixture of propylene glycol and at least 5% by weight of a dipeptide salt selected from the group consisting of the sodium salt of L-aspartyl-L-phenylalanine methyl ester and the potassium salt of L-aspartyl-L-phenylalanine methyl ester.
Claim 2
Dependent Claim
44 words
A concentrated liquid low calorie sweetening composition comprising a mixture of propylene glycol and at least 5% by weight of a dipeptide salt selected from the group consisting of the sodium salt of L-aspartyl-L-phenylalanine methyl ester and the potassium salt of L-aspartyl-L-phenylalanine methyl ester.
Claim 3
Dependent Claim
28 words
The composition of claim 1 wherein the salt is incorporated in the propylene glycol in an amount sufficient to render the propylene glycol nearly saturated at refrigeration temperature.
Claim 4
Dependent Claim
