Abstract
A steviol glycoside composition with reduced surface tension. The reduced surface tension steviol glycoside composition includes an aqueous solution of a steviol glycoside and a surface tension reducing compound in an amount effective to reduce surface tension. Method for reducing surface tension in a steviol glycoside solution includes contacting a steviol glycoside and a surface tension reducing compound.
Claims23
A method for reducing surface tension in a steviol glycoside solution, the method comprising:
- adding one or more steviol glycosides and a surface tension reducing compound to an aqueous solution to form a steviol glycoside solution;
- wherein surface tension of the steviol glycoside solution is reduced relative to an equivalent solution lacking the surface tension reducing compound;
- wherein the surface tension reducing compound comprises:
- (i) one or more monocaffeoylquinic acids or salts thereof;
- (ii) at least 20% (wt) of one or more dicaffeoylquinic acids or salts thereof;
- and
- (iii) at least one of an ester of ferulic acid and quinic acid, an ester of sinapic acid and quinic acid, an ester of p-coumaric acid and quinic acid, an ester of caffeic acid and 3-(3,4-dihydroxyphenyl)lactic acid, an ester of caffeic acid and tartaric acid, and isomers thereof;
- and
- wherein the one or more steviol glycosides and the surface tension reducing compound are added such that the steviol glycoside solution comprises a 1:0.5 to 1:4 ratio by weight of steviol glycose to surface tension reducing compound.
A method for preparing a beverage concentrate solution with reduced surface tension, the method comprising:
- adding to an aqueous solution i) one or more steviol glycosides and ii) a surface tension reducing compound to form a beverage concentrate solution, wherein the beverage concentrate solution has reduced surface tension relative to an equivalent beverage concentrate solution lacking the surface tension reducing compound;
- wherein the surface tension reducing compound comprises:
- (i) one or more monocaffeoylquinic acids or salts thereof;
- (ii) at least 20% (wt) of one or more dicaffeoylquinic acids or salts thereof, and
- (iii) at least one of an ester of ferulic acid and quinic acid, an ester of sinapic acid and quinic acid, an ester of p-coumaric acid and quinic acid, an ester of caffeic acid and 3-(3,4-dihydroxyphenyl)lactic acid, an ester of caffeic acid and tartaric acid, and isomers thereof;
- and
- wherein the one or more steviol glycosides and the surface tension reducing compound are added such that the beverage concentrate solution comprises a 1:0.5 to 1:4 ratio by weight of steviol glycose to surface tension reducing compound.
