Gum base is the non-nutritive, non-digestible, water-insoluble masticatory delivery system used to carry sweeteners, flavors and any other desired substances in chewing gum and bubble gum. It provides all the basic textural and masticatory properties of gum.
Gum bases for chewing gum are different from those for bubble gum. A bubble gum base is formulated with the ability to blow bubbles; it contains higher levels of elastomers or higher molecular weight polymers for this purpose. Gum bases for non-acid flavored gum use calcium carbonate as a filler, while gum bases for acid flavored gum use talc as a filler, since acids can react with calcium carbonate to produce a gas, which is undesirable.
Bubble gum usually contains 15-20% gum base, while chewing gum contains 20-25% gum base and sugar-free chewing gum contains 25-30% gum base.
Researchers at the University of Illinois at Urbana and at Wm. Wrigley Jr. Company are studying the possibility of making gum base with biodegradable zein (corn protein).
Large chewing gum manufacturers generally produce their own gum base in-house while small chewing gum producers usually buy gum base from third-party suppliers.
