Publication number: 20210093563Abstract: A method is provided of making a medicinal delivery system which satiates a craving in an individual when the medicinal delivery system is administered orally to the individual. A coating composition is applied on a saliva-soluble powder to establish a coated powder, the coating composition featuring an at least partially solubilized craving satiation medicinal compound. The coated powder is combined with an edible carrier base to establish a medicinal delivery system that rapidly releases medicine and buffer preferably followed by slower, sustained release.Type: ApplicationFiled: October 13, 2020Publication date: April 1, 2021Inventors: Tommy L.

Patent number: 5059416Abstract: 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.Type: GrantFiled: June 26, 1989Date of Patent: October 22, 1991Assignee: Warner-Lambert CompanyInventors: Subraman R.

Patent number: 5043169Abstract: 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.Type: GrantFiled: May 25, 1990Date of Patent: August 27, 1991Assignee: Warner-Lambert CompanyInventors: Subraman R. Cherukuri, Tommy L. Chau, Gul Mansukhani, Angel M. Orama
