  • Publication number: 20070098842
    Abstract: 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.

  • Publication number: 20060286200
    Abstract: A method of producing a candy product includes providing a core including a first flavoring agent. The core is coated with a first layer to form a first coated product. The first layer may be a hydrophobic layer or a hydrophilic layer. The first coated product is coated with a second layer including a second flavoring agent to form an encapsulated particle. The second layer may be a hydrophobic layer or a hydrophilic layer. A plurality of the encapsulated particles is mixed with a base material to form a candy composition. The candy composition is formed into a candy product.

  • Publication number: 20060159819
    Abstract: 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.

  • Patent number: 5075118
    Abstract: A method for mixing sugarless xylitol containing chewing gums wherein a substantially homogeneous mixture of gum base, alditols other than xylitol, softener, and flavor is first formed, and the xylitol is added to the substantially homogeneous mixture. The mixing schedule enhances gum handling and processing.

  • Patent number: 4988518
    Abstract: A chewing gum product having a core portion including chewable gum base, sweetener and flavoring. The core portion has deposited on its surface a rolling compound including a powdered ingredient selected from the group consisting of sucrose, mannitol, starch, calcium carbonate, talc, lactitol, palatinit, lactose, and combinstions thereof. The rolling compound further includes between about 0.1 and about 2.5 weight percent of a liquid flavor. The rolling compound is substantially free of anti-caking agents and flow agents.
