Abstract
Surfactants are used in low concentrations in order to solubilize water-insoluble solids for inclusion in aqueous beverages. Beverage concentrates, beverage syrups and finished beverages, all of which contain surfactant and water-insoluble solids, are stable; the concentrates and finished beverages are clear.
Claims55
A method of forming a stable, clear beverage concentrate, said stable, clear beverage concentrate containing water-insoluble solids, comprising dissolving said water-insoluble solids in a non-aqueous solvent to form a solution;
- and adding a surfactant to said solution to form said stable, clear beverage concentrate, wherein the weight ratio of said water-insoluble solids to said surfactant ranges from about 1.5:1 to about 5:1 and said stable, clear beverage concentrate is not a microemulsion.
A method of forming a stable beverage syrup, said stable beverage syrup containing water-insoluble solids, comprising the steps of:
- (a) dissolving said water-insoluble solids in a non-aqueous solvent to form a solution;
- and adding a surfactant to said solution to form a stable, clear concentrate, wherein the weight ratio of said water-insoluble solids to said surfactant ranges from about 1.5:1 to about 5:1 and said stable, clear concentrate is not a microemulsion;
- and
- (b) adding an aliquot of said concentrate to a beverage syrup to form said stable beverage syrup.
A method of forming a stable, clear beverage, said stable, clear beverage containing water-insoluble solids, comprising the steps of:
- (a) dissolving said water-insoluble solids in a non-aqueous solvent to form a solution;
- and adding a surfactant to said solution to form a stable, clear concentrate, wherein the weight ratio of said water-insoluble solids to said surfactant ranges from about 1.5:1 to about 5:1 and said stable, clear concentrate is not a microemulsion;
- (b) adding an aliquot of said stable, clear concentrate to a beverage syrup to form a stable beverage syrup;
- and
- (c) diluting said stable beverage syrup to form said stable, clear beverage.
A method of forming a stable beverage concentrate, said stable beverage concentrate containing water-insoluble solids, comprising the step of:
- (a) dissolving said water-insoluble solids in a non-aqueous solvent to form a solution;
- and adding a surfactant to said solution to form said stable beverage concentrate, wherein the weight ratio of said water-insoluble solids to said surfactant ranges from about 1.5:1 to about 5:1 and said stable beverage concentrate is not a microemulsion.
A method of forming a stable beverage, said stable beverage containing water-insoluble solids, comprising the steps of:
- (a) dissolving said water-insoluble solids in a non-aqueous solvent to form a solution;
- and adding a surfactant to said solution to form a stable beverage concentrate, wherein the weight ratio of said water-insoluble solids to said surfactant ranges from about 1.5:1 to about 5:1 and said stable beverage concentrate is not a microemulsion;
- (b) adding an aliquot of said stable beverage concentrate to a beverage syrup;
- and
- (c) diluting said beverage syrup to form said stable beverage.
