  • Environmentally friendly chewing gum compositions containing elastic protein-based polymers and method of making it
    Patent number: 5580590
    Abstract: A chewing gum composition is provided comprising a water soluble gum portion and a water insoluble gum base portion including an elastic protein-based polymer. Additionally, a method for creating an environmentally acceptable chewing gum is provided comprising the steps of creating a chewing gum base that includes a sufficient amount of elastic protein-based polymer to create a resultant chewing gum that is more environmentally acceptable than a chewing gum without elastic protein-based polymer, and adding to the chewing gum base a water soluble portion to create the resultant chewing gum.

  • Wax-free chewing gum base
    Patent number: 5424080
    Abstract: A gum base, as well as methods for making same, is provided which is free of wax, but has an increased glass transition temperature. It has been found by removing or reducing gum base vinyl polymer softeners that the glass transition temperature of the gum base can be raised to a temperature wherein even at elevated ambient temperatures, blocking (agglomeration) does not occur.

  • Use of tocopherol to stabilize chewing gum rubber
    Patent number: 5270060
    Abstract: A chewing gum elastomer is stabilized with a specific mixture of tocopherol homologs, thereby eliminating the need for synthetic antioxidants. The mixture of tocopherol homologs falls within the range of 7-20% by weight alpha tocopherol, 45-75% by weight gamma tocopherol, 18-32% by weight delta tocopherol and, optionally, 0-3% by weight beta tocopherol.

  • Gum compositions containing vinyl laurate/vinyl acetate copolymer
    Patent number: 5173317
    Abstract: Chewing gum and chewing gum bases containing vinyl laurate/vinyl acetate copolymer as a primary elastomer component are provided. The gum compositions also contain certain elastomer plasticizers, softeners, and low melting point waxes. The chewing gum bases provided are substantially free of polyvinyl acetate and glycerol triacetate, and are particularly useful in bubble gum compositions.
