Coextruded chewing gum containing a soft non-SBR gum core portion

A coextruded chewing gum having a soft gum center portion, comprising an extruded soft gum core portion formed of chewing gum containing at least about 5% up to about 10% by weight moisture based on the weight of the core portion and an outer shell portion formed of chewing gum having a harder consistency than said core portion, said soft core portion comprising a polyisobutylene elastomer or a mixture of medium and lower molecular weight polyisobutylene elastomers having a molecular weight within the range of from about 750,000 to 1,300,000 and 37,000 to 80,000, respectively, in an amount of from about 0.5% to about 25% by weight of said core portion gum base, plasticizers comprising glyceryl triacetate and acetylated monoglyceride in an amount of from about 0.5% to about 25% by weight of said core portion gum base, one or more hydrophilic-type detackifiers which absorb saliva and become slippery, one or more filler-texturizing agents, one or more softening agents having a melting point above about 22.degree. C., one or more emulsifiers which function as slip agents and impart hydrophilic properties to the elastomer, and an anti-tack combination comprising a polyterpene resin, one or more waxes to enhance bite through characteristics, and optionally a polyethylene wax, said outer shell portion formed of chewing gum formulations generally known in the art and extruded simultaneously with said core portion so that said outer shell portion is bonded to said core portion to provide a support and protective barrier therefor to retain said moisture in said core portion and retard migration of moisture therefrom.
