The present invention is a directed at a sweetening agent delivery system having prolonged sweetness release prepared by a method which comprises the steps of (A) providing the following ingredients in percentages by weight of the sweetening agent delivery system (a) a solution of a high intensity sweetening agent, wherein the sweetening agent is present in an amount from about 0.01% to about 60%, (b) polyvinyl acetate present in an amount from about 40% to about 93% and having a molecular weight in the range from about 2,000 to about 100,000, (c) a plasticizing agent present in an amount from about 0.1% to about 20%, (d) a waxy material having a melting point from about 30.degree. C. to about 120.degree. C. present in an amount from about 0.5% to about 40%, and (e) an emulsifying agent present in an amount from about 0.1% to about 20%, (B) melting and blending the polyvinyl acetate with the plasticizing agent to form a uniform mixture, (C) admixing the solution of high intensity sweetening agent with the melted mixture from step (B) and evaporating the solvent to form a uniform mixture, (D) admixing the waxy material and the emulsifying agent with the mixture from step (C) to form a uniform mixture, (E) cooling and blending the mixture from step (D), and (F) granulating the mixture from step (E).

Microencapsulated high intensity sweetening agents having prolonged

A new delivery system for zinc compounds and the process for its preparation is disclosed, which has use in a variety of products including comestibles such as chewing gum compositions, confections, pharmaceuticals, food products such as vitamin preparations, dentifrice compositions and throat lozenges. More particularly, this invention relates to a process for preparing a zinc compound delivery system comprised of a zinc core material coated with a first hydrophilic coating comprising a hydrocolloid material and a second hydrophobic coating selected from the group consisting of fats, waxes and mixtures thereof. The delivery system provides enhanced masking of the bitter flavor characteristic of zinc compounds, as well as reduced grittiness with retained stability at the elevated temperatures of product formulation.

Zinc compound delivery system with improved taste and texture

A stabilized dipeptide sweetening composition useful in chewing gum applications provides longer shelf life stability and improved longer lasting sweetness. A dipeptide sweetner such as appartame is encapsulated through an anhydrous process that compresses the crystals with a mixture of inert binder ingredients so as to form a solid tablet or sheet which is then ground into fine granular particles. These particles may then be coated with a hydrophobic material such as a fat or wax and then incorporated into a variety of food applications such as chewing gum. The sweetener composition is thereby protected from adverse environmental conditions such as high temperature, moisture and pH.

Stabilized Sweetner Composition

A free-flowing particulate delivery system for providing enhanced flavor and sweetness to comestible compositions comprising a powdered flavor composition encapsulated in a matrix comprising an outer hydrophilic coating containing up to the solubility limit of the coating of an intense sweetener. The delivery system is particularly useful in chewing gums, confectioneries and pharmaceutical preparations as well as other food products.

Multiple encapsulated flavor delivery system and method of preparation

Chewing gum compositions resistant to moisture pickup and hardening and having a moisture content less than about 1.0% and preferably less than about 0.3% by weight of the final composition, including a hard or a soft gum base, flavoring agent, sweetening agent, and a hydrophobic softening agent. The present composition may be formed without cooling and does not require conditioning prior to wrapping. Prior to wrapping the gum pieces may be coated with a sweetening agent in the known manner at ambient temperatures and up to 80% relative humidity.
