Patent number: 7767243Abstract: A method of preparing a liquid flavoring composition includes combining menthol and at least one physiological cooling agent selected from the group consisting of N-substituted p-menthane carboxamides, acyclic carboxamides, menthyl succinate and combinations thereof. The menthol and the at least one physiological cooling agent are heated to form a liquid composition. The composition of the menthol and the at least one physiological cooling agent is cooled to about 25° C. while maintaining the composition in a liquid state to create the liquid flavoring composition.Type: GrantFiled: December 22, 2005Date of Patent: August 3, 2010Assignee: WH. Wrigley Jr. CompanyInventors: David L. Witkewitz, Gordon N. McGrew

Publication number: 20080199565Abstract: A method for producing a chewing gum, as well as the chewing gum so produced, incorporates a physiological cooling agent, such as acyclic carboxamide, or combinations of physiological cooling agents. In another embodiment a combination of physiological cooling agents is made in a modified release structure. The modified release/cooling agents combination is preferably obtained by physically modifying the properties of the combination of cooling agents by coating and drying. When incorporated into gum, these particles are adapted to enhance the shelf stability of the flavor and/or produce a modified release when the gum is chewed. In another embodiment, the physiological cooling agent is present with menthol and menthone. In another embodiment, coated chewing gum has a coating that comprises a physiological cooling agent. The preferred inventive chewing gum provides a high flavor impact in which the harsh notes normally associated with such a high flavor impact have been reduced or eliminated.Type: ApplicationFiled: April 29, 2008Publication date: August 21, 2008Inventors: Fred R. Wolf, Gordon N. McGrew, Jeffrey S. Hook, Lindell C. Richey, Mansukh M. Patel, Robert J. Yatka, David L. Witkewitz, Michael J. Greenberg, Henry T. Tyrpin, Kathryn T. Nelson

Patent number: 6955827Abstract: A method for producing a chewing gum with a controlled release of an antimicrobial agent, as well as the chewing gum so produced, is obtained by physically modifying the release properties of the antimicrobial agent by coating and drying. The antimicrobial agent is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated antimicrobial agent is preferably then co-dried and particle sized to produce a release-modified antimicrobial agent for use in chewing gum. When incorporated into the chewing gum, these particles are adapted to produce a fast release or a delayed release when the gum is chewed. The preferred antimicrobial agent is chlorhexidine digluconate.Type: GrantFiled: July 14, 2003Date of Patent: October 18, 2005Assignee: Wm. Wrigley Jr. CompanyInventors: Roman M. Barabolak, Steven E.
