PROPYLENE GLYCOL-FREE SPRAY-DRIED COMPOSITIONS AND METHODS OF PRODUCING THE SAME
The present invention relates to stable, propylene glycol-free and glycerin-free, spray-dried compositions containing flavors and optional surfactants for use in optically clear, liquid beverages and liquid beverage concentrates.
1 . A stable, propylene glycol-free and glycerin-free, spray-dried flavor composition produced by spray drying a flavor that contains volatile compounds and an optional surfactant in a spray dryer having an inlet temperature of less than 100° C. and an air inlet dew point −10° C. to 5° C.
2 . The spray-dried flavor composition of claim 1 , wherein the spray-dried flavor composition is further dried in a fluid bed chamber attached at the spray dryer outlet, wherein the temperature of the air of the fluid-bed unit is at or below the outlet temperature of the spray dryer.
3 . The spray-dried flavor composition of claim 1 , wherein the surfactant comprises a polysorbate, a polyglycerol fatty acid ester, a diglyceride ester of diacetyltartaric acid, a monoglyceride ester of diacetyltartaric acid or quillaja extract.
4 . The spray-dried flavor composition of claim 3 , wherein the polysorbate comprises polysorbate 20, polysorbate 40, polysorbate 60 or polysorbate 80.
5 . The spray-dried flavor composition of claim 3 , wherein the polyglycerol fatty acid ester comprises polyglyceryl-3 stearate, polyglyceryl-6 distearate, polyglyceryl-10 stearate, polyglyceryl-10 dipalmitate, olyglyceryl-10 oleate, and polyglyceryl-10 caprylate/caprate.
6 . The spray-dried flavor composition of claim 1 , wherein the volatile compounds are acetaldehydes, dimethyl sulfides, ethyl acetates, ethyl propionates, methyl butyrates, or ethyl butyrates.
7 . The spray-dried flavor composition of claim 1 , wherein the volatile compounds have a boiling point of less than 200° C., less than 100° C., or less than 60° C.
8 . The spray-dried flavor composition of claim 1 , further comprising a carrier material.
9 . The spray-dried flavor composition of claim 8 , wherein the carrier material is a sugar, sugar alcohol, sugar derivative, modified starch, protein, cellulose, salt, dextrin, polyol, peptide, acid, carbohydrate or hydrocolloid.
10 . The spray-dried flavor composition of claim 1 , wherein the flavor further comprises a solvent.
11 . The spray-dried flavor composition of claim 10 , wherein the solvent is a volatile solvent.
12 . The spray-dried flavor composition of claim 1 , wherein the air inlet temperature is in the range of 40° C. to 99° C.
13 . The spray-dried flavor composition of claim 1 , wherein the water activity of the composition is in the range of 0.1 to 0.6.
14 . The spray-dried flavor composition of claim 1 , wherein said composition provides a high intensity flavor.
15 . A liquid beverage or liquid beverage concentrate comprising the spray-dried flavor composition of claim 1 .
16 . The liquid beverage or liquid beverage concentrate of claim 15 , wherein said liquid beverage or liquid beverage concentrate comprises an acidulant.
