Gum base is a non-nutritive masticatory substance. (US FDA, “Code of Federal Regulation”).
It is an inert and insoluble non-nutritive product used as a support for the edible and soluble portion of the chewing gum (sugar, glucose, polyols and flavours).
The general description "gum base", used on chewing gum products throughout the world, is recognised by The Food Chemicals Codex and most national legislation.
Gum base is produced through a blend of raw materials which can be categorized in five classes:

Elastomers, act as the key ingredient and provide elasticy

Resins act as binders and softeners

Plasticizers render the elastomer soft to ensure thorough blending of the gum base

Fillers contribute to the overall texture

Antioxidants prevent oxidation of the gum base and flavors during shelf life

Through close cooperation with customers, Gum Base Co.'s has developed many "tailor-made” gum bases that allow customers to produce their own, unique quality products, which can create the competitive edge and distinguish their brands among others.
