This non-adhesive solution for chewing gum on dental work and dentures, however, remains an ineffective environmental one as the cud stays water insoluble and made of polymeric hydrocarbons which bond to asphalt and rubber shoes, making it both very expensive and difficult to remove in large pedestrian areas. (Refer to an earlier July 7, 2014 post on Chewing gum for a list of patents that address the chewing gum environmental issue).
Below you will find the abstract for US
4241091, titled Calorie-free non adhesive
chewing gums and method, and above an image of Freedent gum, with the properties
described in the patent.
A substantially calorie-free,
non-carbohydrate, non-cariogenic, non-adhesive chewing gum is provided which
does not adhere to dentures and includes gum base,
substantially calorie-free sweetener, flavor, water, thickener, filler,
softener and a slip agent for imparting non-adhesive properties to the gum, the
slip agent being alpha-cellulose, texturized vegetable protein, fish protein
concentrate, citrus peel, citrus pulp, fruit pulp or mixtures thereof. A method
for imparting non-adhesive properties to chewing gum is also provided. The
resulting chewing gum has significantly higher cud volume than heretofore known
chewing gum of equivalent weight.
* Cud = what remains of the water insoluble portion of the gum. Cud volume
matters especially for bubble gum since it is not possible to blow bubbles with
small cuds.
