Abstract
Abstract The present invention relates to a gum composition exhibiting improved shelf life and resistance to staling, and which comprises a substantially anhydrous mixture of a gum base, at least one sugar alcohol, and glycerin, the glycerin being present In an amount ranging from about 8% to about 18% by weight of the composition. The gum composition preferably contains no more than 2% by weight of water. The invention includes a method for preparing the gum composition, comprising treating the ingredients thereof, including the glycerin, to remove substantially all water therefrom, thereafter combining the sugar alcohol with the glycerin under agitation and at an elevated temperature, and adding subsequently thereto the gum base, after which certain additive materials, such as flavourings, and the like may be added with mixing. The compositions of the present invention retain softness and desirable chewing sensation after storage in atmospheres of low relative humidity, for periods of time of up to one year. The present composition and method of preparation do not adversely effect the other desirable properties of the gum compositions, and both regular chewing gums and bubble gums may be prepared in this way. The present invention is particularly useful in the instance where sugar-free gum compositions are contemplated.
