Abstract
Chewing gum containing gum base, erythritol and flavor, but which is free of added water and hygroscopic ingredients, is environmentally stable, i.e., does not absorb significant amounts of water from the atmosphere to soften with age, or give off significant amounts of water to the atmosphere to harden or stiffen with age.
Claims16
A chewing gum composition which does not significantly gain or lose moisture when exposed to high or low humidity conditions, consisting essentially of:
- a) from about 5% to about 95%, by weight of the gum, of gum base;
- b) from about 4.9% to about 94.9% by weight of the gum, of erythritol;
- and
- c) from about 0.1% to about 10%, by weight of the gum, of flavor;
- d) the gum composition containing less than 0.25% of water and ingredients which have an equilibrium moisture content of more than about 7% at 20.degree. C. and a relative humidity of 78%.
A chewing gum composition which does not significantly gain or lose moisture when exposed to high or low humidity conditions, consisting essentially of:
- a) from about 5% to about 95%, by weight of the gum, of gum base;
- b) from about 4.9% to about 94.9% by weight of the gum, of erythritol;
- and
- c) from about 0.1% to about 10%, by weight of the gum, of flavor;
- d) the gum composition containing less than 0.25% of water and ingredients which have an equilibrium moisture content greater than that of xylitol at the same temperature and relative humidity conditions.
