Abstract

A beverage product containing a first azo-component and a second azo-component in a weight about 1:999 to about 999:1; an electrolyte; and a solvent, wherein the first azo-component and the second-component remain in solution for at least thirty days.

First claim

We claim:

1. A beverage product comprising:
(a) a first food grade azo-dye and a second food grade azo-dye, wherein the first food grade azo-dye and the second food grade azo-dye are present in a combined amount of about 0.05 wt % to about 6 wt % of the beverage product;
(b) an electrolyte salt in an amount of 0.03 wt % to about 20 wt % of the beverage product, and
(c) a solvent,
wherein the second food grade azo-dye is different from the first food grade azo-dye, wherein the first food grade azo-dye and the second food grade azo-dye are each selected from Red 40, Yellow 5, and Yellow 6,
wherein the weight ratio of the first food grade azo-dye to the second food grade azo-dye is about 1:9 to about 9:1, and
wherein the beverage product is in the form of a solution and the first food grade azo-dye and the second food grade azo-dye remain in solution for at least seven days under refrigeration.

2. The beverage product of claim 1 , further comprising a third food grade azo-dye selected from Red 40, Yellow 5, and Yellow 6, wherein the first, second, and third food grade azo-dye are present in a combined amount of about 0.01 wt % to about 6 wt % of the beverage product.

3. The beverage product of claim 1 , wherein the first food grade azo-dye is Red 40 and the second food grade azo-dye is Yellow 5.

4. The beverage product of claim 1 , further comprising a non azo-dye colorant.

5. The beverage product of claim 4 , wherein the non azo-dye colorant is an anthocyanin-based natural color, Blue 1, turmeric, curcumin, cochineal, betanin, indigoid, or a combination thereof.

6. The beverage product of claim 4 , wherein the non azo-dye colorant is Blue 1.

7. The beverage product of claim 1 , wherein the beverage product contains no more than 0.12 wt % benzaldehyde.

8. The beverage product of claim 1 , wherein the weight ratio of the first food grade azo-dye to the second food grade azo-dye is about 1:4 to about 4:1.

9. The beverage product of claim 1 , wherein the electrolyte salt is included in an amount of 0.03 wt % to about 3 wt % of the beverage product.

10. A beverage product comprising:
(a) a first food grade azo-dye and a second food grade azo-dye, wherein the first food grade azo-dye and the second food grade azo-dye are present in a combined amount of about 0.05 wt % to about 6 wt % of the beverage product;
(b) an electrolyte salt in an amount of 0.03 wt % to about 20 wt % of the beverage product, and
(c) a solvent,
wherein the second food grade azo-dye is different from the first food grade azo-dye,
wherein the first food grade azo-dye and the second food grade azo-dye are each selected from Red 40, Yellow 5, and Yellow 6,
wherein the weight ratio of the first food grade azo-dye to the second food grade azo-dye is about 1:9 to about 9:1, and
wherein the beverage product is in the form of a solution.

11. The beverage product of claim 10 , further comprising a third food grade azo-dye selected from Red 40, Yellow 5, and Yellow 6, and wherein the first, second, and third food grade azo-dye are present in a combined amount of about 0.01 wt % to about 6 wt % of the beverage product.

12. The beverage product of claim 10 , wherein the first food grade azo-dye is Red 40 and the second food grade azo-dye is Yellow 5.

13. The beverage product of claim 10 , further comprising a non azo-dye colorant.

14. The beverage product of claim 13 , wherein the non azo-dye colorant is an anthocyanin-based natural color, Blue 1, turmeric, curcumin, cochineal, betanin, indigoid, or a combination thereof.

15. The beverage product of claim 13 , wherein the non azo-dye colorant is Blue 1.

16. The beverage product of claim 10 , wherein the beverage product contains no more than 0.12 wt % benzaldehyde.

17. The beverage product of claim 10 , wherein the weight ratio of the first food grade azo-dye to the second food grade azo-dye is about 1:4 to about 4:1.

18. The beverage product of claim 10 , wherein the electrolyte salt is included in an amount of 0.03 wt % to about 3 wt % of the beverage product.

19. A beverage product comprising:
(a) a food grade azo-dye in an amount of about 0.01 wt % to about 6 wt % of the beverage product;
(b) a non azo-component colorant;
(c) an electrolyte salt in an amount of about 0.03 wt % to about 20 wt % of the beverage product; and
a solvent, (d)
wherein the food grade azo-dye is selected from Red 40, Yellow 5, Yellow 6, or a combination thereof,
wherein the non azo-component colorant is an anthocyanin-based natural color, Blue 1, turmeric, curcumin, cochineal, betanin, indigoid, or a combination thereof, and
wherein the beverage product is in the form of a solution, and the non azo-component colorant is included in an amount effective to prevent precipitation of the food grade azo-dye for at least seven days under refrigeration.

20. The beverage product of claim 19 , wherein the non azo-component colorant is Blue 1.

21. The beverage product of claim 19 , wherein the beverage product contains no more than 0.12 wt % benzaldehyde.

22. The beverage product of claim 19 , wherein the non azo-dye is included in an amount of up to 2 wt % of the beverage product.

23. The beverage product of claim 19 , wherein the food grade azo-dye includes a combination of Yellow 5 and Red 40.

24. The beverage product of claim 19 , wherein the electrolyte salt is included in an amount of 0.03 wt % to about 3 wt % of the beverage product.

25. A beverage product comprising:
