Abstract

Color indicating chewing gum compositions comprising one or more color compounds are provided. The compositions demonstrate a visual color or shade change from start of chewing to the end of chewing and provide oral health benefits. Methods of producing a color changing chewing gum are also provided.

First claim

What is claimed is:

1. A method of producing a color changing chewing gum comprising admixing a water insoluble gum base portion, a water soluble bulk portion, and a flavor to form a gum matrix of a color changing chewing gum, wherein at least one color compound is admixed with both the water insoluble gum base portion and the water soluble bulk portion, wherein admixing the at least one color compound with the water insoluble gum base portion is a separate step from admixing the at least one color compound with the water soluble bulk portion, and wherein admixing the at least one color compound with the water insoluble gum base portion includes adding to the water insoluble gum base portion a water insoluble color compound or an oil soluble color compound to be retained therein throughout chewing, such that the color changing chewing gum produced visually changes in color from an original color of the color changing chewing gum to a color of the water insoluble color compound or the oil soluble color compound during chewing.

2. The method of claim 1 , wherein the at least one color compound includes at least one water soluble color compound that is admixed with both the water soluble bulk portion and the water insoluble gum base portion, and wherein the at least one water soluble color compound is selected from the group consisting of FD&C Blue 2 dye, liquid caramel, FD&C Red 40, FD&C Yellow 5, FD&C Yellow 6, FD&C Green 3, betanin, spirulina, gardenia, and combinations thereof.

3. The method of claim 1 , wherein admixing the at least one color compound with the water soluble bulk portion includes adding a water insoluble color compound to the water soluble bulk portion.

4. The method of claim 1 , wherein admixing the at least one color compound with the water soluble bulk portion includes adding an oil soluble color compound to the water soluble bulk portion, and wherein the oil soluble color compound is selected from the group consisting of beta carotene, Beta Apo 8′ Carotenal, paprika oleoresin, canthaxanthin, and combinations thereof.

5. The method of claim 1 , wherein the color changing chewing gum comprises from about 0.05% to about 5.0% by weight of a water soluble color compound.

6. The method of claim 1 , wherein the color changing chewing gum comprises from about 0.004% to about 5.0% by weight of a water insoluble color compound.

7. The method of claim 1 , wherein the color changing chewing gum comprises from about 0.05% to about 5.0% by weight of a water soluble color compound, and from about 0.004% to about 5.0% by weight of a water insoluble color compound.

8. The method of claim 1 , wherein the color changing chewing gum comprises from about 0.004% to about 0.01% by weight of an oil soluble color compound.

9. The method of claim 1 , wherein the color changing chewing gum comprises from about 0.001% to about 5.0% by weight of color compound selected from lakes, pigments, and combinations thereof.

10. A method of producing a color changing chewing gum comprising admixing a water insoluble gum base portion, a water soluble bulk portion, and a flavor to form a gum matrix of a color changing chewing gum, wherein at least one color compound is incorporated into the water insoluble gum base portion and wherein incorporating the at least one color compound into the water insoluble gum base portion is performed by adding solely to the water insoluble gum base portion a water insoluble color compound or an oil soluble color compound to be retained therein throughout chewing, such that the color changing chewing gum produced visually changes in color from an original color of the color changing chewing gum to a color of the water insoluble color compound or the oil soluble color compound during chewing.

11. The method of claim 10 , wherein the color changing chewing gum comprises from about 0.05% to about 5.0% by weight of a water soluble color compound, and wherein the original color of the color changing chewing gum is a mixture of the water soluble color compound and the water insoluble color compound or the oil soluble color compound.

12. The method of claim 10 , wherein the color changing chewing gum comprises from about 0.004% to about 5.0% by weight of a water insoluble color compound.

13. The method of claim 10 , wherein the color changing chewing gum comprises from about 0.004% to about 0.01% by weight of an oil soluble color compound.

14. The method of claim 10 , wherein the color changing chewing gum comprises from about 0.001% to about 5.0% by weight of color compound selected from lakes, pigments, and combinations thereof.

15. A method of producing a color changing chewing gum comprising admixing a water insoluble gum base portion, a water soluble bulk portion, and a flavor to form a gum matrix of a color changing chewing gum, wherein at least one color compound is incorporated into the water soluble bulk portion and wherein incorporating the at least one color compound into the water soluble bulk portion is performed by adding solely to the water soluble bulk portion a water soluble color compound to be dissipated therewith during chewing, such that the color changing chewing gum produced visually changes in color from an original color of the color changing chewing gum to a lighter shade of the original color, to a color of a water insoluble color compound or an oil soluble color compound, or to a white or off-white color during chewing.

16. The method of claim 15 , wherein the color changing chewing gum comprises from about 1.0% to about 5.0% by weight of a water soluble color compound.

17. The method of claim 15 , wherein the color changing chewing gum comprises from about 0.004% to about 5.0% by weight of a water insoluble color compound.

18. The method of claim 15 , wherein the color changing chewing gum comprises from about 0.004% to about 0.01% by weight of an oil soluble color compound.

19. The method of claim 15 , wherein the color changing chewing gum comprises from about 0.001% to about 5.0% by weight of a color compound selected from lakes, pigments, and combinations thereof.

20. The method of claim 15 , wherein the color changing chewing gum comprises from about 0.05% to about 5.0% by weight of a water soluble color compound, and from about 0.004% to about 5.0% by weight of a water insoluble color compound.
