<p>Gums that are capable of changing color during use are provided. The color change results from one or more coloring agents in the gum which can cause a release of different colors as the gum is chewed. The coloring agent can include a variety of different combinations of materials, such as encapsulated coloring materials, dyes, lakes, dispersions, pH sensitive coloring materials and combinations thereof. In this regard, the gum of the present invention can produce gum bubles that are differently colored, such as uniformly colored and/or multi-colored, during use.</p> |
