Gum base

Gum base is the non-digestible component of chewing gum, providing its characteristic chewy texture. It is typically a blend of synthetic polymers, resins, and waxes, though natural resins like chicle were historically used. The exact composition is proprietary to manufacturers but is designed to be inert and stable.

Manufacturers add gum base to chewing gum and bubble gum to give the product its elasticity and chewability. It acts as a binder and texturiser, allowing the gum to be chewed for extended periods without breaking down. It is the primary functional ingredient in these confectionery items.

Gum base is authorised as a food additive in Great Britain and is listed on the Register of Food Additive Authorisations. It is generally considered to be biologically inert and is not absorbed by the body, meaning it passes through undigested. European food safety authorities have evaluated it, and it is not associated with adverse health effects when consumed as part of chewing gum. There are no widespread controversies regarding its safety.
