Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A chewing gum product having improved shelf-life and flavor duration comprising gum base, sweetener, and a mixture of one or more flavors and a limonene derivative, said mixture being substantially uniformly dispersed throughout said gum base, said one or more flavors being present in an amount within range of from about 0.3 to about 2% by weight of the chewing gum, and said limonene derivative being present in an amount within the range of from about 0.1 to about 1.5% by weight of the chewing gum, said limonene derivative inhibiting or minimizing migration of said one or more flavors from said gum base thereby enhancing flavor duration and preserving flexibility of the chewing gum during storage.
