Biodegradable chewing gum bases containing one or more crosslinked polyesters, and methods of making and using thereof are described herein. In one embodiment, the base contains a first monomer derived from a saturated or unsaturated lipid, such as a saturated or unsaturated hydroxy fatty acid, optionally a second monomer derived from a saturated or unsaturated polyol, such as a saturated or unsaturated polycarboxylic acid or polyhydroxy compound, and optionally a third monomer, such as a saturated or unsaturated monocarboxylic acid, polycarboxylic and/or hydroxy acid having 5 carbons or less. The polyesters can be crosslinked in the presence of a free radical initiator via thermally-initiated or photo-initiated free radical polymerization. The chewing gum bases are rubbery at room temperature, have a low degree of tackiness and have low glass transition temperatures. One or more additive can be incorporated and/or active agents can also be incorporated into the chewing gum base.
