  • 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.
