Chewing gum containing compositions for controlled release of flavor bearing substances and process for producing same

Claim 1

A chewing gum composition consisting essentially of a chewing gum base having dispersed therein sweetener and flavor bearing polymeric particles, each of said polymeric particles consisting essentially of: (a) at least one water-soluble normally solid polymer; (b) at least one water-insoluble normally solid polymer; (c) (i) at least one flavor composition, a portion of which is incorporated in the water-insoluble polymer and a portion of which is incorporated in the water-soluble polymer; and (ii) at least one sweetener composition, a portion of which is incorporated in the water-insoluble polymer and a portion of which is incorporated in the water-soluble polymer; the water-soluble polymer and the water-insoluble polymer being physically associated with each other and in such a manner that one is in the form of a multiplicity of discrete entities in a matrix of the other produced according to the process consisting essentially of the sequential steps of: (a) first mixing a water-soluble polymer and a water-insoluble polymer to form a first polymer blend; (b) then adding to the polymer blend at least one sweetener composition and at least one flavor composition; (c) then mixing the resulting blend to form a second polymer blend; (d) then cooling the resulting second polymer blend to a substantially solid state to form a substantially solid bland; (e) then grinding the resulting substantially solid blend to form a particulate substantially solid flavor and sweetener composition; and then (f) admixing the resulting particulate substantially solid flavor and sweetener composition with a chewing gum base.
