15. A process for preparing a substantially moistureless chewing gum composition having a moisture content of from zero to about 0.3% which comprises:
-
(a) softening the gum base in a temperature range of about 40°
C. to about 60°
C.;(b) admixing with the gum base said medicament, a sweetening agent and a flavoring agent, said agents being substantially moistureless;
continuing to mix until a homogenous, pliable mixture is obtained;(c) extruding the composition; (d) forming the composition into suitable chewing gum pieces without cooling; and (e) wrapping the resultant product. - View Dependent Claims (16, 17, 18)
