  • Publication number: 20130156885
    Abstract: A method for producing a chewing gum and confections, as well as the chewing gum and confections so produced, incorporates 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 and confections, these particles are adapted to enhance the shelf stability of the flavor and/or produce a modified release. In another embodiment, coated chewing gum has a coating that comprises combinations of physiological cooling agents. 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: 20070248717
    Abstract: A method for producing a confection such as chewing gum, as well as the confection so produced, incorporates a blend of physiological cooling agents, including menthyl glutarate and one or more of L-isopulegol and p-menthane-3,8-diol. In another embodiment the blend 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 blend of physiological cooling agent is included in a confection coating.

  • 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: 20060240145
    Abstract: The present invention includes a method for producing a chewing gum with a modified release sweetener selected from the group of N-substituted derivatives of aspartame, particularly neotame, as well as the chewing gum so produced. The modified release neotame or other N-substituted derivative of aspartame sweetener is obtained by physically modifying the sweetener properties by coating and drying. Neotame or another N-substituted derivative of aspartame sweetener is coated by encapsulation, partially coated by agglomeration, entrapped by absorption or extrusion, or treated by multiple steps of encapsulation, agglomeration, absorption, or extrusion. The coated sweetener is then co-dried and particle sized to produce a release-modified high-intensity sweetener. When incorporated into the chewing gum, these particles are adapted to enhance the shelf stability of the sweetener and/or produce a modified release when the gum is chewed.

  • Publication number: 20050202118
    Abstract: Chewing gums and methods of making same that have improved flavor duration by stimulating a trigeminal nerve of a consumer of the chewing gum are provided. The chewing gums of the present invention includes a trigeminal stimulant. The trigeminal stimulant stimulates the trigeminal nerve of the consumer to provide longer lasting flavor duration.

  • Publication number: 20050008747
    Abstract: A method of forming a sugarless coating on chewing gum cores comprises: providing chewing gum cores; providing a coating syrup comprising one or more sugarless sweeteners; providing a dusting mix comprising about 20% to about 60% of a bulk sweetener selected from the group consisting of malitol, hydrogenated isomaltulose, lactitol, sorbitol and mixtures thereof and about 40% to about 80% filler; and applying a plurality of layers of the coating syrup and a plurality of layers of the dusting mix to the chewing gum cores to form a sugarless coating on the gum cores.

  • Patent number: 4986991
    Abstract: A chewing gum composition having an extended sweetness and flavor comprising a chewable gum base and a sweetener comprising 4,1',6'-trichloro-4,1',6'-trideoxy-galactosucrose (TGS), also known as sucralose. the gum base preferably comprises polyvinyl acetate, wax, and fats and oils. Within the initial 2 minutes of chewing, the TGS releases from said gum at a rate less than about 8 sucrose equivalents per minute, and at about 10 minutes of chewing, said TGS releases from said gum at a rate greater than about 3 sucrose equivalents per minute. To improve sweetness and flavor balance, a portion of the TGS is modified to make it fast releasing or a fast release sweetener is added to the chewing gum. The chewing gum is manufactured by mixing chewing gum ingredients including the chewable gum base and the sweetener in any conventional manner.
