Spray-dried compositions capable of retaining volatile compounds and methods of producing the same
The present invention relates to spray-dried compositions capable of retaining volatile compounds and methods relating to the same. The present invention also relates to the powders produced by such methods.
1. A method for producing a spray-dried flavor composition capable of retaining volatile compounds comprising spray drying a flavor containing volatile compounds in a spray dryer, the spray dryer having an inlet temperature of less than 100° C. and an inlet air humidity of 0—4 g H 2 O/kg dry air and having an outlet temperature between 35° C. and 55° C. and an outlet air humidity of 10—20 g H 2 O/kg dry air to obtain a spray-dried flavor composition, wherein the volatile compounds are present in the spray-dried flavor composition in an amount that is at least 20% of the volatile compounds originally contained in the flavor, and the spray-dried flavor composition has a stronger flavor than a control flavor after storage for at least 12 weeks at a temperature of at least 32° C.
2. The method of claim 1 , further comprising drying the spray-dried flavor composition 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 method of claim 1 , wherein the volatile compounds are acetaldehydes, dimethyl sulfides, ethyl acetates, ethyl propionates, methyl butyrates, or ethyl butyrates.
4. The method of claim 1 , wherein the volatile compounds have a boiling point of less than 200° C.
5. The method of claim 1 , wherein the flavor emulsion further comprises a carrier material.
6. The method of claim 1 , wherein the flavor further comprises a solvent.
7. The method of claim 6 , wherein the solvent is a volatile solvent.
8. The method of claim 5 , wherein the flavor and carrier material comprise 40% and 70% as dry solid material of the total composition.
9. The method of claim 1 , wherein air of the spray dryer is partially or wholly nitrogen or carbon dioxide.
10. The method of claim 1 , wherein the water activity of the composition is in the range of 0.1 to 0.6.
11. A spray-dried flavor composition produced by the method of claim 1 , wherein the water activity of the composition is in the range of 0.1 to 0.6.
12. The spray-dried flavor composition of claim 11 , wherein the spray-dried flavor composition is incorporated into gums, confections, oral care products, beverages, snacks, dairy products, soups, sauces, condiments, detergents, fabric softeners and other fabric care products, antiperspirants, deodorants, talc, kitty litter, hair care and styling products, personal care products, air fresheners, cereals, baked goods or cleaners.
13. The spray-dried flavor composition of claim 11 , wherein the spray-dried flavor composition is incorporated into a chewing gum or beverage.
