Abstract
A coated chewing gum element about 25 to 99.9% by weight of a chewing gum centre having at least one environmentally degradable elastomeric or resinous polymer and about 0.1 to 75% by weight of an outer coating and processes for providing the chewing gum. The outer coating is a hard sugar or sugarless coating, a film coating or a soft coating. The application of an outer coating prevents degradation of the degradable polymers prior to chewing due to physical or chemical effects, thereby improving the shelf life of the environmentally degradable chewing gum. After chewing, the chewing gum will degrade in the environment and can be removed more readily than chewing gum based on non-degradable polymers.
