Abstract
Abstract A non-adhesive chewing gum base composition demonstrates reduced adhesion, and improved chewing satisfaction, and consists essentially of an elastomer, at least one emulsifier including lecithin, lecithin derivatives, or mixtures thereof in an amount of from 0.5% to 6.0%, an elastomer solvent including the glyceryl ester of partially hydrogenated wood rosin, the latter present in an amount of from about 2.5% to about 8%, as well as one or more mineral adjuvants, a non-toxic vinyl polymer and at least one oleaginous plasticizer. Preferably, the wood rosin elastomer solvent is present in an amount ranging from 2.5 to 5%. A method for preparing the present chewing gum base composition is also disclosed, which comprises mixing the ingredients of the base composition in one step. Preferably, the elastomer is charged first, and subject to high shear, after which the remaining components are added and shearing is continued. The present invention is more economical, as it eliminates adherence to critical processing parameters.
