A coated chewing gum element comprising about 25 to 99.9 % by weight of a chewing gum centre comprising at least one environmentally degradable elastomeric or resinous polymer and about 0.1 to 75 % by weight of an outer coating an 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.

L'invention porte sur un chewing-gum enrobé comprenant environ entre 25 et 99,9 % en poids d'un noyau comprenant au moins un polymère élastomère ou résineux dégradable, sans danger pour l'environnement, et environ de 0,1 à 75 % en poids d'un enrobage. L'invention porte également sur les procédés de préparation de ce chewing-gum. L'enrobage est un sucre dur ou un enrobage sans sucre, un film ou un enrobage mou. L'application d'un enrobage empêche la dégradation des polymères dégradables avant la mastication du fait des effets physiques ou chimiques, ce qui prolonge la durée de vie du chewing-gum dégradable, sans danger pour l'environnement. Après mastication, le chewing-gum se dégrade dans l'environnement et peut être retiré plus facilement que le chewing-gum à base de polymères non dégradables.
