Abstract
Low density chewing gums having a density of less than 0.60 g/cc comprise at least 50% polymer and less than 40% bulking agent and filler combined. The low density chewing gum may be produced by mixing the ingredients with supercritical fluid carbon dioxide and cooling the mixture. The mixture may optionally be cut into pieces and coated.

A chewing gum comprising at least 50 wt. % polymer, less than 40 wt. % of bulking agent and filler combined wherein the chewing gum has an envelope density of less than 0.60 g/cc.
A method of making a chewing gum comprising the steps of;
- introducing ingredients comprising at least a polymer into an extruder;
- introducing supercritical fluid carbon dioxide into the extruder;
- operating the extruder to mix the ingredients and the supercritical carbon dioxide;
- and extruding the mixture to produce a low-density chewing gum.
A chewing gum comprising at least 60 wt. % polymer, less than 30 wt. % of bulking agent and filler combined wherein the chewing gum has an envelope density of less than 0.60 g/cc.
