a chewing gum including at least one biodegradable polymer , wherein the molecular weight of the polymer is at least 105 , 000 g / mol . according to the invention , it has moreover been realized that various problems associated with the prior art may be effectively dealt with by increasing the molecular weight of at least one of the biodegradable polymers in the chewing gum when compared to conventional chewing gum polymers and thereby increasing the robustness of the chewing gum with respect to softeners , emulsifiers and e . g . flavor .
