Abstract

A sugarless hard coated chewing gum comprising a sugarless chewing gum center and a sugarless hard coating containing hydrogenated isomaltulose. The chewing gum center has a low water content, preferably less than about 2.5 weight percent based on the weight of the gum center. The sugarless hard coated chewing gum is manufactured by applying to the chewing gum center a sugarless syrup comprising hydrogenated isomaltulose to coat the gum centers. The coated gum centers are then dried in an inert medium such as air to form the hard coating.

Claims

1. A hard coated sugarless chewing gum comprising a sugarless chewing gum center and a sugarless hard coating comprising hydrogenated isomaltulose, said gum center having a water content of less than about 2.5 weight percent based on the weight of the gum center.

2. The gum of claim 1 wherein the coating comprises hydrogenated isomaltulose and other coating ingredients and the hydrogenated isomaltulose constitutes greater than about 50 weight percent of the coating.

3. The gum of claim 1 wherein the coating comprises hydrogenated isomaltulose and other coating ingredients and the hydrogenated isomaltulose constitutes greater than 90 weight percent of the coating.

4. The gum of claim 1 wherein the coating further contains a flavoring agent.

5. The gum of claim 1 wherein the coating further contains an artificial sweetener.

6. The gum of claim 1 wherein the coating further contains a dispersing agent.

7. The gum of claim 6 wherein the dispersing agent comprises titanium dioxide.

8. The gum of claim 1 wherein the coating constitutes about 10 to about 75 weight percent of the coated chewing gum.

9. The gum of claim 1 wherein the chewing gum center has a water content of less than about 1.5 weight percent.

10. The gum of claim 1 wherein the chewing gum center has a water content of less than about 1.0 weight percent.

11. The gum of claim 1 wherein the chewing gum center comprises an insoluble gum base.

12. The gum of claim 1 wherein the insoluble gum base constitutes between about 5 to about 95 weight percent of the chewing gum center.

13. The gum of claim 1 wherein the chewing gum center further comprises a bulking agent.

14. The gum of claim 13 wherein the bulking agent constitutes between about 5 to about 95 weight percent of the chewing gum center.

15. The gum of claim 13 wherein the bulking agent comprises a sweetener.

16. The gum of claim 13 wherein the bulking agent comprises sorbitol, mannitol, hydrogenated isomaltulose, xylitol, maltitol, hydrogenated starch hydrolysate, or combinations thereof.

17. The gum of claim 15 wherein the sweetener comprises sorbitol.

18. The gum of claim 1 wherein the gum center further comprises a softener.

19. The gum of claim 18 wherein the softener constitutes between about 0.5 to about 15.0 weight percent of the chewing gum center.

20. The gum of claim 18 wherein the softener comprises glycerine.

21. The gum of claim 18 wherein the softener comprises an aqueous sweetener solution.

22. The gum of claim 21 wherein the aqueous solution comprises sorbitol, hydrogenated starch, hydrolysates, corn syrup, or combinations thereof.

23. The gum of claim 18 wherein the softener contains less than about 30 weight percent water.

24. The gum of claim 1 wherein the chewing gum center further comprises a flavoring agent.

25. The gum of claim 1 wherein the chewing gum center further comprises an artificial sweetener.

26. A sugarless hard coated chewing gum comprising a sugarless chewing gum center and a sugarless hard coating containing hydrogenated isomaltulose, said gum center comprising in admixture an insoluble gum base, a bulking agent and a softener, said softener having a water content less than about 30 weight percent.

27. The gum of claim 26 wherein said softener comprises glycerine, sorbitol, glycerols, glycerides, lecithin, vegetable oils, aqueous sweetener solutions or combinations thereof.

28. A method of manufacturing a sugarless hard coated chewing gum which comprises applying to a sugarless chewing gum center which has a water content of less than about 2.5 weight percent a sugarless syrup comprising hydrogenated isomaltulose to obtain a coated gum center and drying the coated gum center under drying conditions to form said sugarless hard coated chewing gum.

29. The method of claim 28 wherein the syrup temperature is between about 100°

to about 200°

F.

30. The method of claim 28 wherein the syrup composition comprises between about 60 to about 75 weight percent hydrogenated isomaltulose.

31. The method of claim 28 wherein the syrup composition further comprises a dispersing agent.

32. The method of claim 28 wherein the syrup composition further comprises an artificial sweetener.

33. The method of claim 28 wherein the syrup composition further comprises a flavoring agent.

34. The method of claim 28 wherein the syrup is applied by spraying.

35. The method of claim 28 wherein the coated gum is dried in forced air at a temperature range of about 90°

F. to about 150°

F.

36. The method of claim 35 wherein the drying air has a relative humidity of less than about 15 percent.

37. The method of claim 35 wherein the drying conditions include an air flow rate of about 2800 ft³ /min.

38. The method of claim 28 further comprising applying a flavoring agent to the coated chewing gum.

39. The method of claim 35 further comprising applying a flavoring agent to the coated chewing gum and the agent is dried in the absence of forced air.

40. The method of claim 28 wherein a plurality of coatings are applied to the chewing gum center.

41. The method of claim 40 wherein about 30 to about 60 coats are applied.

42. The method of claim 40 wherein a flavoring agent is applied during at least two of the plurality of coatings.

43. The method of claim 28 wherein the coating is applied to the chewing gum center in an amount sufficient to constitute about 10 to about 75 weight percent of the coated chewing gum.

44. The method of claim 28 wherein the chewing gum center comprise an insoluble gum base.

45. The method of claim 28 wherein the chewing gum center comprises sorbitol, mannitol, isomalt, xylitol, maltitol, sucralose, hydrogenated starch hydrolysates, or combinations thereof.

46. The method of claim 28 wherein the chewing gum center comprises glycerine.

47. The method of claim 28 wherein the chewing gum center comprises a flavoring agent.
