Chewing gum with delayed-interaction modifier

A method of producing a chewing gum having increased environmental acceptability comprising incorporating a food-acceptable delayed-interaction modification agent into a primary chewing gum composition comprising a gum base, a sweetener and a flavoring agent, the delayed-interaction modification agent being present in an amount sufficient such that, when the gum is chewed for 12 minutes and a chewed cud is formed, the delayed-interaction modification agent reacts with the primary chewing gum composition and causes the primary chewing gum composition to exhibit increased environmental acceptability after the chewed cud is discarded, as compared to a chewing gum of the same composition but without the delayed-interaction modification agent;

• wherein the delayed-interaction modification agent is physically or chemically prevented from substantially interacting or reacting with a targeted primary chewing gum component of the composition until after the gum has been chewed and discarded, and wherein a modification agent comprises between about 5% and about 50% by weight of the delayed-interaction modification agent, wherein the modification agent comprises lipase and wherein the chewed cud comprises at least one fat that remains in the gum cud after chewing.
