  • Chewing gum containing high-potency sweetener particles with modified zein coating
    Patent number: 4931295
    Abstract: The present invention is a method for producing a chewing gum with a zein coated delayed release high-potency sweetener. In accordance with the invention, the zein coating is modified so as to be softer so that the sweetener particles are less crunchy and perceptible in the chewing gum. The process beings by mixing a quantity of zein, solvent for the zein, and a water soluble modified cellulose compound, such as hydroxypropyl methylcellulose, together to form a modified zein solution. The amount of the inclusion material is preferably about 5 to about 40 percent by weight of the zein. This modified zein solution is applied to a high-potency sweetener and then dried to produce the delayed release sweetener particles. These particles are then added to a chewing gum formulation.

  • Method of making chewing gum
    Patent number: 4806364
    Abstract: A method of making chewing gum is disclosed which reduces the incidence of "sugar spots." The method begins by providing a sweetener matrix in a mixer. Discrete particles of unmelted gum base, e.g. commercially available gum base pellets, are then added to the mixer. These two components are mixed until a homogenous mass is produced. Preferably, the sweetener matrix contains no more than about 13 percent by weight moisture at the time the gum base particles are added.
