Abstract

An improved carbonated protein beverage/drink composition which provides a relatively high protein content, ranging from about 2% by weight to about 15% by weight, while simultaneously employing a carbonation concentration between about 0.1 volumes of carbonation (per volume of liquid drink solution or liquid drink suspension) to about 4 volumes of carbonation. Preferably the protein is whey protein. The carbonated protein beverage has been heat treated to inactivate microbes in the presence of the carbonation which is used to provide taste and mouth feel for the drink. Typically, the treatment for microbe inactivation is carried out in the individual package used for storage and handling of the carbonated protein drink.

Claims

1. A carbonated whey protein beverage composition suitable for human consumption, comprising:

about 2% by weight to about 15% by weight whey protein, wherein the source of said whey protein is whey protein isolate that is essentially free of caseinate and lactose;

about 0.1 volumes to about 4 volumes of carbon dioxide gas present per volume of whey protein beverage liquid composition; and

wherein said carbonated whey protein beverage composition exibits a pH ranging from about 2.0 to about 3.4, wherein both, at the time of packaging of the carbonated whey protein beverage and during subsequent storage without refrigeration for a time period of at least one year after packaging, substantial solubility of the whey protein is maintained in the beverage composition, and said carbonated whey protein beverage is essentially free of active microbes known to be harmful to human health.

2. A carbonated whey protein beverage composition in accordance with claim 1, wherein said weight % of whey protein present ranges from about 3% by weight to abont 10% by weight.

3. A carbonated whey protein beverage composition in accordance with claim 2, wherein said weight % of whey protein present ranges from about 5% by weight to about 8% by weight.

4. A carbonated whey protein beverage composition in accordance with claim 1, or claim 2, or claim 3, wherein said essentially free from active microbe condition is created by the inactivation of microbes in the individual container in which said carbonated whey protein beverage composition is packaged.

5. A carbonated whey protein beverage composition in accordance with claim 4, wherein said inactivation was accomplished using a timed temperature condition of the carbonated whey protein beverage, while said carbonated whey protein beverage is contained in said individual container.

6. A carbonated whey protein beverage composition in accordance with claim 1, or claim 2, or claim 3, wherein said carbonation ranges from about 1.6 volumes to about 35 volumes per volume of liquid in said carbonated whey protein beverage.

7. A carbonated whey protein beverage composition in accordance with claim 6, wherein said carbonation ranges from about 1.7 volumes to about 3.0 volumes per volume of liquid in said carbonated protein beverage.

8. A carbonated whey protein beverage in accordance with claim 6, wherein said beverage comprises at least one additional ingredient selected from the group consisting of an anti-foaming agent, a nutrient, an herbal supplement, a flavoring agent, a sweetener, and a coloring agent.

9. A carbonated whey protein beverage in accordance with claim 1, or claim 2, or claim 3, wherein said beverage comprises at least one additional ingredient selected from the group consisting of an anti-foaming agent, a nutrient calcium or a calcium derivative, an herbal supplement, a flavoring agent a sweetener, and a coloring agent.

10. A method of preparing a carbonated whey protein beverage. comprising:

admixing in water a whey protein isolate that is essentially free of caseinate and lactose to achieve a percent by weight of whey protein in the admixture of about 2% to about 15% an anti-foaming agent, and an amount of a ph adjusting agent to provide a ph of between about 2 and about 3.4, thereby obtaining an admixture;

heating said admixture to atexuperature ranging from about 140°

F. to about 188°

F. for a time period ranging from about 60 seconds to about 10 seconds;

cooling said admixture to a temperature of about 40°

F. or less over a tame period ranging from about 5 minutes to about 10 minutes;

adding carbon dioxide to said admixture to obtain a carbonated whey protein beverage wherein the amount of carbonation present in said admixture ranges from about 0.1 volumes per volume of liquid admixture to about 4.0 volumes per volume of liquid admixture; and

packaging said carbonated whey protein beverage in a container which may be stored without refrigeration for more than one year before use by a consumer of the carbonated whey protein beverage.

11. A method in accordance with claim 10, wherein said temperature maximum duririgheatingis about 150°

F.

12. A method in accordance with claim 10 or claim 11, wherein additional ingredients are admixed into said admixture prior to heating of said admixture, and said additional ingredients include at least one ingredient selected from the group consisting of a nutrient, an herbal supplement, a flavoring agent;

a sweetener, and a coloring agent.

13. A method in accordance with claim 12, wherein said carbonated whey protein beverage is clear in color, exhibiting essentially no turbidity.

14. A method of preparing a carbonated whey protein beverage, comprising:

admixing in water a whey protein isolate that is essentially free of caseinate and lactose to achieve a percent by weight of whey protein in the admixture of about 2% to about 15%, an anti-foaming agent, and an amount of a pH adjusting agent to provide a pH of between about 2 and about 5.5, thereby obtaining an admixture;

adding carbon dioxide to said admixture to obtain a carbonated protein beverage wherein the amount of carbonation present in said admixture ranges. from about 0.1 volumes per volume of liquid admixture to about 4.0 volumes per volume of liquid admixturer;

packaging said carbonated whey protein drink beverage in a container designed for use by a consumer of the carbonated whey protein beverage; and

treating said admixture to inactivate biologically active microbes;

wherein the packaged and treated carbonated whey protein beverage may be stored without refrigeration for more than one year before use by a consumer of the carbonated whey protein beverage.

15. A method in accordance with claim 14, wherein said pH maximum is about 3.4.

16. A method in accordance with claim 14 or claim 15, wherein additional ingredients arc admixed into said admixture prior to inactivation of said biologically active microbes, and said additional ingredients include at least one ingredient selected from the group consisting of a nutrient, an herbal supplement, a flavoring agent, a sweetener, and a coloring agent.

17. A method in accordance with claim 16, wherein said carbonated whey protein beverage is clear in color, exhibiting essentially no turbidity.

18. A method in accordance with claim 14 or claim 15, wherein said treatment of said admixture to inactivate biologically active microbes is carried out in an individual container in which said carbonated whey protein beverage is subsequently stored and handled by a consumer of the beverage.

19. A method in accordance with claim 18, wherein additional ingredients are admixed into said admixture prior to inactivation of said biologically active microbes, and said additional ingredients include at least one ingredient selected from the group consisting of a nutrient, an herbal supplement, a flavoring agent, a sweetener, and a coloring agent.
