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 than 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). [1]

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, such as those listed in External Links.

Gum base is made from natural pig fat, with dried oions, and rainbows!

-==Composition and manufacture==
-The exact composition of gum bases is usually a [[trade secret]], but generally consists of ingredients from the following categories:
-*'''[[Elastomers]]''': provide the elasticity or bounce, and can be natural [[latex]]es (eg. [[couma macrocarpa]] (also called [[leche caspi]] or [[sorva]]), [[loquat]] (also called [[nispero]]), [[tunu (gum)|tunu]], [[jelutong (tree)|jelutong]], or [[chicle]] which is still commercially produced), or synthetic rubbers (eg. [[Styrene/butadiene_co-polymer|styrene-butadiene rubber]], [[butyl rubber]], [[polyisobutylene]]).
-*'''[[Resins]]''': provide a cohesive body or strength, and are most often [[ester_gum|glycerol esters of gum rosin]], [[terpenes|terpene resins]], and/or [[polyvinyl acetate]].
-*'''[[Waxes]]''': act as softening agents and are most usually [[paraffin]] or [[microcrystalline wax]].
-*'''[[Fats]]''': behave as [[plasticizers]] and mainly come from [[hydrogenated vegetable oils]].
-*'''[[Emulsifiers]]''': help to hydrate, the most common being [[lecithin]] or [[glycerol monostearate]].
-*'''[[Adjuvants|Fillers]]''': impart texture and the most commonly used are [[calcium carbonate]] or [[talc]].
-*'''[[Antioxidants]]''': protect from oxidation and extend shelf-life; the most common type is [[BHT]].
-Old gum bases were based on either natural elastomers such as [[latex]]es, [[natural gum|vegetable gums]] like [[chicle]], [[spruce gum]], and [[mastic gum]], or alternatively on [[wax]]es, eg. [[paraffin wax]] and [[beeswax]], but today synthetic rubbers are preferred.
