Abstract

The invention relates to inactivating mold spores in a beverage using pasteurization in the presence of natamycin and to a beverage comprising natamycin and mycosamine.

First claim

The invention claimed is:

1. A beverage having a pH of from 2.0 to 4.0 when measured at 20±2° C., wherein the beverage comprises an antifungal agent consisting of an effective amount of natamycin and mycosamine; and
wherein mold spores of Aspergillus in the beverage are inactivated.

2. The beverage according to claim 1 , wherein the amount of each of natamycin and mycosamine in the beverage is from 0.1 to 100 ppm based on the total weight of said beverage.

3. The beverage according to claim 2 , wherein the amount of each of natamycin and mycosamine in the beverage is from 0.2 to 50 ppm based on the total weight of the beverage.

4. The beverage according to claim 3 , wherein the amount of each of natamycin and mycosamine in the beverage is from 0.3 to 25 ppm based on the total weight of the beverage.

5. The beverage according to claim 4 , wherein the amount of natamycin in the beverage is from 10 to 20 ppm based on the total weight of the beverage.

6. The beverage according to claim 5 , wherein the amount of natamycin in the beverage is about 10 ppm based on the total weight of the beverage.

7. The beverage according to claim 1 , wherein the beverage is selected from the group consisting of iced tea, flavored water, fruit juice, a carbonated beverage, and lemonade.

8. The beverage according to claim 1 , wherein the beverage is pasteurized.

9. The beverage according to claim 1 , wherein the beverage comprises at least one additional compound selected from the group consisting of an acidity regulator, an anticaking agent, an antifoaming agent, an antioxidant, a color, a color retention agent, a surfactant, an emulsifier, an additional preservative, and a dispersant.

10. The beverage according to claim 1 , wherein the beverage is microbially stable.

11. The beverage according to claim 1 , wherein the natamycin is present in an amount of less than 0.04 mg/L and the mycosamine is present in an amount of 2 mg/L.

12. A beverage comprising an antifungal agent consisting of an effective amount of natamycin and mycosamine, wherein the beverage is produced by subjecting the beverage having a pH of from 2.0 to 4.0, measured at 20±2° C. to a temperature of from 50° C. to 90° C. in the presence of natamycin and mycosamine; and
wherein mold spores of Aspergillus in the beverage are inactivated.

13. The beverage according to claim 12 , wherein the temperature is from 65° C. to 85° C.

14. The beverage according to claim 12 , wherein the temperature is from 80° C. to 90° C.

15. The beverage according to claim 12 , wherein the amount of each of natamycin and mycosamine in the beverage is from 0.1 to 100 ppm based on the total weight of said beverage.

16. The beverage according to claim 12 , wherein the natamycin is present in an amount of less than 0.04 mg/L and the mycosamine is present in an amount of 2 mg/L.

17. The beverage according to claim 12 , wherein the beverage is selected from the group consisting of iced tea, flavored water, fruit juice, a carbonated beverage, and lemonade.

18. The beverage according to claim 12 , wherein the beverage comprises at least one additional compound selected from the group consisting of an acidity regulator, an anticaking agent, an antifoaming agent, an antioxidant, a color, a color retention agent, a surfactant, an emulsifier, an additional preservative, and a dispersant.

19. The beverage according to claim 12 , wherein the beverage is microbially stable.
