Claims20
A method of producing a color changing chewing gum comprising admixing a water insoluble gum base portion, a water soluble bulk portion, and a flavor to form a gum matrix of a color changing chewing gum, wherein at least one color compound is admixed with both the water insoluble gum base portion and the water soluble bulk portion, wherein admixing the at least one color compound with the water insoluble gum base portion is a separate step from admixing the at least one color compound with the water soluble bulk portion, and wherein admixing the at least one color compound with the water insoluble gum base portion includes adding to the water insoluble gum base portion a water insoluble color compound or an oil soluble color compound to be retained therein throughout chewing, such that the color changing chewing gum produced visually changes in color from an original color of the color changing chewing gum to a color of the water insoluble color compound or the oil soluble color compound during chewing.
A method of producing a color changing chewing gum comprising admixing a water insoluble gum base portion, a water soluble bulk portion, and a flavor to form a gum matrix of a color changing chewing gum, wherein at least one color compound is incorporated into the water insoluble gum base portion and wherein incorporating the at least one color compound into the water insoluble gum base portion is performed by adding solely to the water insoluble gum base portion a water insoluble color compound or an oil soluble color compound to be retained therein throughout chewing, such that the color changing chewing gum produced visually changes in color from an original color of the color changing chewing gum to a color of the water insoluble color compound or the oil soluble color compound during chewing.
A method of producing a color changing chewing gum comprising admixing a water insoluble gum base portion, a water soluble bulk portion, and a flavor to form a gum matrix of a color changing chewing gum, wherein at least one color compound is incorporated into the water soluble bulk portion and wherein incorporating the at least one color compound into the water soluble bulk portion is performed by adding solely to the water soluble bulk portion a water soluble color compound to be dissipated therewith during chewing, such that the color changing chewing gum produced visually changes in color from an original color of the color changing chewing gum to a lighter shade of the original color, to a color of a water insoluble color compound or an oil soluble color compound, or to a white or off-white color during chewing.
