Abstract
Abstract The disclosure relates to a sugarless center-filled gum wherein the sugarless chewing gum formulation can be extruded to form a hollow-centered rope and wherein the sugarless center-fill is not absorbed into the chewing gum. Both the chewing gum and the liquid fill have incorporated therein a composition comprising a natural or synthetic gum, glycerin humectant and an additional humectant which may be sorbitol solution or a combination of sorbitol solution and propylene glycol. Suitable synthetic or natural gums include carboxymethylcellulose, pectin, propylene glycol alginates, agar and gum tragacanth. The preferred composition which is incorporated into both the sugarless chewing gum formulation and the sugarless liquid fill contains sodium carboxymethylcellulose, glycerin and sorbitol solution.
