A rolling compound containing about 80-95 weight per cent mannitol and about 5-20 weight per cent sorbitol has improved flow and results in improved chewing gum quality. Initially, the sorbitol has been prepared into a fine powder that has a particle size distribution similar to that of mannitol. Chewing gum compositions which have been dusted with the rolling compound process well and possess excellent flavor and appearance. |

DETAILED DESCRIPTION In accordance with the invention, there is provided a rolling compound blend which includes between about 80%-95% by weight mannitol and between about 5-20% by weight sorbitol, wherein the sorbitol particles have been selected or reduced in size such that the particle sizes of the mannitol and sorbitol are at least approximately similar to each other.
Specifically, the sorbitol particles used in the invention are selected or modified such that at least 95% by weight of the sorbitol particles used in the rolling compound blend have at least one peripheral dimension which does not exceed 100 mesh, so that the particles can pass through a 100 mesh screen.
Preferably, at least 99% by weight of the sorbitol particles used in the invention have at least one peripheral dimension which does not exceed 100 mesh.
Most preferably, at least 99.
5% by weight of the sorbitol particles have at least one peripheral dimension which does not exceed 100 mesh.
Ordinarily, sorbitol might not be considered for use as a flow agent.
Sorbitol is known to absorb moisture and become sticky and tacky.
Furthermore, commercially available crystalline sorbitol generally has much larger particle sizes than mannitol, suggesting that relatively small amounts of sorbitol would contribute little or nothing to improving the flow of relatively larger amounts of mannitol.
Accordingly, the present invention contemplates selecting or modifying the sorbitol particle sizes such as to approximate the size of the powdered mannitol particles.
When this is done, it has been found that a blend of fine powdered sorbitol and powdered mannitol, in the invention concentrations, has flow properties which are similar to or better than the blend of 93% by weight mannitol and 7% by weight talc.
By using fine powdered sorbitol instead of talc as the flow agent, the flavor of the chewing gum can also be improved.
With the foregoing in mind, it is a feature and advantage of the invention to provide a primarily mannitol containing rolling compound which has equal or better flow than the blend of 93% mannitol and 7% talc, but which does not contain talc
