Abstract

Chewing gums incorporating Alitame in a manner to delay its release, separate the Alitame from gum ingredients which cause the Alitame to degrade, or both, are disclosed. The Alitame may be coated by an encapsulating agent applied by spray drying, fluid bed coating, fiber spinning or coaservation techniques, agglomeration, and fixation or entrapment/absorption plus encapsulation or agglomeration. Also, the Alitame may be incorporated in a physically separate part of the gum, such as a center fill, a part of a rolling compound, or a part of a panning composition.

Claims

1. A chewing gum composition comprising:

(a) about 5 to about 95% of a gum base;

(b) about 10 to about 90% of a bulking agent;

(c) about 0.1 to about 10% of a flavoring agent; and

(d) coated Alitame wherein at least one of the said gum base ingredients, bulking agents, or flavoring agents is also an Alitame degradation agent and wherein the Alitame is sufficiently coated to slow Alitame degradation due to the degradation agent so that at least 60% of an original amount of Alitame in the chewing gum remains after 8 weeks of storage at 85°

F.

2. The chewing gum composition of claim 1 wherein the Alitame comprises from about 0.005 to about 0.10% of the total gum composition.

3. The chewing gum composition of claim 1 wherein the chewing gum is a sugarless chewing gum.

4. The chewing gum composition of claim 3 wherein the bulking agent comprises a sugar alcohol selected from the group consisting of sorbitol, mannitol, xylitol, maltitol, hydrogenated starch hydrolysates and mixtures thereof.

5. The chewing gum of claim 1 wherein the Alitame is coated by a material selected from the group consisting of acrylic polymers, carboxyvinyl polymers, polyamides, polystyrene, polyvinyl acetate, polyvinyl acetate phtalate, polyvinylpyrolidone and copolymers thereof.

6. The chewing gum composition of claim 1 wherein the Alitame is coated by a material selected from the group consisting of agar alginates, guar gum, gum tragacanth, carrageenan, and xanthan gum.

7. The chewing gum composition of claim 1 wherein the Alitame is coated by a material which comprises a cellulose derivative selected from the group consisting of ethyl cellulose, methyl cellulose, sodium hydroxymethyl cellulose, hydroxypropylmethyl cellulose and modified starches.

8. The chewing gum composition of claim 1 wherein the Alitame is coated by a material selected from the group consisting of shellac, Zein and gelatin.

9. A method of making a chewing gum with Alitame comprising the steps of:

(a) providing from about 5 to about 95% gum base, about 10 to about 90% of a bulking agent, and about 0.1 to about 10% of a flavoring agent, at least one of said bulking and flavoring agents also being an Alitame degradation agent;

(b) coating a quantity of Alitame with a coating material which slows Alitame degradation due to the Alitame degradation agent so that at least 60% of an original quantity of Alitame formulated in the gum remains after 8 weeks of storage at 85°

F.; and

(c) mixing the coated Alitame, the gum base, bulking agent and flavoring agent to make a chewing gum composition.

10. The method of claim 9 wherein the quantity of Alitame added to the other ingredients is between about 0.005 to about 0.10% of the total gum composition.

11. The method of claim 10 wherein the chewing gum is a sugarless chewing gum.

12. The method of claim 11 wherein the bulking agent further comprises a sugar alcohol selected from the group consisting of sorbitol, mannitol, xylitol, maltitol, hydrogenated starch hydrolysates and mixtures thereof.

13. The method of claim 9 wherein the coating material is selected from the group consisting of acrylic polymers, carboxyvinyl polymers, polyamides, polystyrene, polyvinyl acetate, polyvinyl acetate phtalate, polyvinylpyrolidone and copolymers thereof.

14. The method of claim 9 wherein the coating material is selected from the group consisting of agar alginates, guar gum, gum tragacanth, carrageenan, and xanthan gum.

15. The method of claim 9 wherein the coating material comprises a cellulose derivative selected from the group consisting of ethyl cellulose, methyl cellulose, sodium hydroxymethyl cellulose, hydroxypropylmethyl cellulose and modified starches.

16. The method of claim 9 wherein the coating material is selected from the group consisting of shellac, Zein and gelatin.

17. The method of claim 9 wherein the step of coating the Alitame comprises:

(a) mixing a quantity of Alitame with an encapsulating material; and

(b) agglomerating the encapsulated Alitame.

18. The method of claim 9 wherein the step of coating the Alitame comprises:

(a) mixing a quantity of Alitame with a spray drying solvent and an encapsulating material; and

(b) spray drying the mixture in such a way as to encapsulate the Alitame.

19. The method of claim 9 wherein the step of coating the Alitame comprises fluid bed coating a quantity of Alitame with an encapsulating material dissolved or dispersed in a solvent.

20. A method of making a chewing gum with Alitame comprising the steps of:

(a) providing from about 5 to about 95% gum base, about 10 to about 90% of a bulking agent, and about 0.1 to about 10% of a flavoring agent, at least one of said bulking and flavoring agents also being an Alitame degradation agent;

(b) agglomerating Alitame with an agent which is capable of slowing Alitame degradation so that at least 60% of an original quantity of Alitame formulated in the gum remains after 8 weeks of storage at 85°

F.; and

(c) mixing the coated Alitame, the gum base, bulking agent and flavoring agent to make a chewing gum composition.

21. A method of making a chewing gum with Alitame comprising the steps of:

(a) providing from about 5 to about 95% gum base, about 10 to about 90% of a bulking agent, and about 0.1 to about 10% of a flavoring agent, at least one of said bulking and flavoring agents also being an Alitame degradation agent;

(b) absorbing Alitame in an agent which is capable of slowing Alitame degradation so that at least 60% of an original quantity of Alitame formulated in the gum remains after 8 weeks of storage of 85°

F.; and

(c) mixing the coated Alitame, the gum base, bulking agent and flavoring agent to make a chewing gum composition.
