Abstract

A method of making coated chewing gum products containing an acid blocker comprises the steps of providing chewing gum cores; providing a coating syrup comprising a bulk sweetener, providing an acid blocker, applying the coating syrup and acid blocker to the cores and drying the syrup to produce a coating on the cores, the coating containing the acid blocker.

Claims

1. A coated chewing gum product comprising:

a) a chewing gum core; and

b) a coating on said core, the coating comprising an acid blocker.

2. The coated chewing gum product of claim 1 wherein the acid blocker is selected from the group consisting of histamine H₂- receptor antagonists, gastric proton pump inhibitors and combinations thereof.

3. The coated chewing gum product of claim 1 wherein the acid blocker is a histamine H₂- receptor antagonist selected from the group consisting of cimetidine, famotidine, rantidine and its active salt, nizatidine and combinations thereof.

4. The coated chewing gum product of claim 1 wherein the acid blocker is a gastic proton pump inhibitor selected from the group consisting of omeprazole, rabeprazole and combinations thereof.

5. The coated chewing gum product of claim 1 wherein the coating further comprises a neutralizing antacid.

6. The coated chewing gum product of claim 1 wherein the acid blocker is selected from the group consisting of cimetidine, ranitidine, nizatidine, famotidine and omeprazole.

7. The chewing gum product of claim 1 wherein the acid blocker comprises famotidine and the coating comprises about 30% to about 75% maltitol by weight.

8. The chewing gum product of claim 1 wherein the acid blocker is present at a level in the coating of about 1 mg to about 200 mg per piece of coated gum product.

9. A method of making coated chewing gum products containing an acid blocker comprising the steps of:

a) providing chewing gum cores;

b) providing a coating syrup comprising a bulk sweetener;

c) providing an acid blocker; and

d) applying the acid blocker and coating syrup to the cores and drying the syrup to produce a coating on the cores, the coating containing said acid blocker.

10. The method of claim 9 wherein the bulk sweetener is a polyol.

11. The method of claim 10 wherein the polyol is selected from the group consisting of sorbitol, xylitol, erythritol, maltitol, lactitol, hydrogenated isomaltulose and combinations thereof.

12. The method of claim 9 wherein the bulk sweetener is a sugar.

13. The method of claim 9 wherein the coating further comprises a binding agent.

14. The method of claim 13 wherein the binding agent is selected from the group consisting of gum arabic, gum talha, guar gum , karaya gum, locust bean gum, alginate gums, xanthan gum, arabinogalactan, cellulose derivatives, vegetable gums, gelatin and mixtures thereof.

15. The method of claim 13 wherein the binding agent comprises at least about 2% of the coating.

16. The method of claim 9 wherein the acid blocker is selected from the group consisting of cimetidine, ranitidine, nizatidine, famotidine and omeprazole.

17. The method of claim 9 wherein the acid blocker is mixed into the coating syrup before the syrup is applied to the cores.

18. The method of claim 9 wherein the coating further comprises a high-intensity sweetener.

19. The method of claim 18 wherein the high-intensity sweetener is selected from the group consisting of sucralose, aspartame, N-substituted APM derivatives, salts of acesulfame, alitame, saccharin and its salts, cyclamic acid and its salts, glycyrrhizin, dihydrochalcones, thaumatin, monellin and mixtures thereof.

20. The method of claim 19 wherein the high-intensity sweetener comprises acesulfame K.

21. The method of claim 9 wherein the bulk sweetener comprises maltitol.

22. The method of claim 9 wherein the coating is sugarless.

23. The method of claim 9 wherein a powdered sugar or polyol is applied to the cores after application of the coating syrup.

24. The method of claim 9 wherein the acid blocker in the coating comprises a histamine H₂-receptor antagonist.

25. The method of claim 24 wherein the histamine H₂-receptor antagonist is selected from the group consisting of cimetidine, ranitidine and its active salt, famotidine, nizatidine and mixtures thereof.

26. The method of claim 24 wherein the histamine H₂-receptor antagonist comprises famotidine.

27. The method of claim 23 wherein the acid blocker is mixed with powdered sugar or polyol prior to being applied to the cores.

28. The method of claim 9 wherein the acid blocker is selected from the group consisting of histamine H₂ - receptor antagonists, gastric proton pump inhibitors, and combinations thereof.

29. The method of claim 9 wherein the acid blocker is physically modified prior to being incorporated into the coating.

30. A chewing gum product made by the method of claim 9.

31. A method of making coated chewing gum products containing an acid blocker comprising the steps of:

a) providing chewing gum cores;

b) providing a coating syrup comprising a bulk sweetener;

c) providing a dry charge material comprising a bulk sweetener and an acid blocker; and

d) applying the coating syrup and dry charge material to the chewing gum cores to produce a coating on the cores, the coating comprising said acid blocker.

32. The method of claim 31 wherein the coating comprises about 30% to about 75% maltitol.

33. The method of claim 31 wherein multiple coats of coating syrup and dry charge material are applied to build up the coating.

34. The method of claim 31 wherein the dry charge material and coating syrup both include maltitol as the bulk sweetener.

35. The method of claim 31 wherein the coating further comprises calcium carbonate.

36. The method of claim 35 wherein the calcium carbonate is dispersed in the coating syrup.

37. The method of claim 31 wherein the acid blocker is selected from the group consisting of cimetidine, ranitidine, nizatidine, famotidine and omeprazole.

38. A method of delivering an acid blocker to an individual that provides relief in the gastrointestinal tract comprising the steps of:

a) providing chewing gum cores;

b) providing a coating syrup comprising a bulk sweetener;

c) providing an acid blocker;

d) applying the acid blocker and coating syrup to the cores and drying the syrup to produce a coating on the cores, the coating containing said acid blocker; and

e) chewing the coated chewing gum product in the mouth and swallowing the coating, the coating dispersing and dissolving to provide said acid blocker in the gastrointestinal tract.

39. A method of making coated chewing gum products containing an acid blocker comprising the steps of:

a) providing chewing gum cores;

b) providing a coating syrup comprising;
