Non-crystallizing syrups containing sorbitol and their use in chewing gum
An aqueous syrup for use in chewing gum, particularly pellet gum, comprises, on a dry basis, greater than about 98% polyols, of which i) about 50% to about 90% is sorbitol, ii) about 3% to about 30% is maltitol, iii) about 2% to about 20% are polyols, other than sorbitol and maltitol, with a degree of polymerization (DP) of 1 or 2, and iv) less than about 20% (and perhaps less than about 12%) are polyols with a DP of 3 or greater. The syrup is made with less than about 1.0% plasticizing agent, such as glycerin or propylene glycol. The syrup contains less than 5% water. The syrup can be made by evaporating a mixture of a sorbitol solution, a maltitol syrup and one or more polyols selected from the group consisting of mannitol, xylitol, lactitol, erythritol, hydrogenated isomaltulose, and combinations thereof. Methods of using the syrup to make chewing gum, and chewing gum products containing the syrup are also provided.

iii) about 2% to about 20% are polyols, other than sorbitol and maltitol, with a degree of polymerization (DP) of 1 or 2, and
iv) less than about 20% are polyols with a DP of 3 or greater; and
b) less than about 1.0% plasticizing agent selected from glycerin, propylene glycol and mixtures thereof.

3. The syrup of claim 1 wherein the syrup has a moisture content of about 0.5% to about 5%.
4. The syrup of claim 1 wherein the syrup comprises, on a dry basis; about 70% to about 90% sorbitol, about 5% to about 20% maltitol and about 4% to about 15% polyols with a DP of 1 or 2 other than sorbitol and maltitol.
5. The syrup of claim 1 wherein the syrup has about 3% or less water but does not crystallize when held at 65° C. for one week.
6. The syrup of claim 1 wherein the polyols, other than sorbitol and maltitol, with a DP of 1 or 2 are selected from the group consisting of mannitol, lactitol, hydrogenated isomaltulose, xylitol, erythritol and mixtures thereof.
7. A syrup composition prepared from a sorbitol solution, maltitol, and one or more polyols selected from the group consisting of mannitol, xylitol, lactitol, erythritol, hydrogenated isomaltulose, and combinations thereof; wherein the one or more polyols are present in the syrup at a level of about 2% to about 20% on a dry weight basis, the sorbitol is present in the syrup at a level of at least 50% on a dry weight basis, and the syrup contains between about 2% and about 4% water and less than 1.0% plasticizer.
8. The syrup of claim 7 held in storage at a temperature of about 65° C. for at least one week without undergoing crystallization.
9. A chewing gum composition comprising a homogeneous mixture of gum base and a bulking agent wherein the bulking agent comprises an aqueous sugarless syrup comprising, on a dry basis, about 50% to about 90% sorbitol; about 3% to about 30% maltitol; about 2% to about 20% polyols, other than sorbitol and maltitol, with a DP of 1 or 2; and less than about 20% hydrogenated oligosaccharides having a DP of 3 or greater; the syrup containing at least 98% polyols on a dry basis and less than about 1.0% plasticizing agent selected from glycerin, propylene glycol and mixtures thereof; and wherein the chewing gum composition has less than 2% moisture and said syrup comprises over 20% of said composition.
