O que é Chewing/Bubble Gum Base? Aplicações, dosagem, alternativas e especificações

Gum Base, also known as chewing gum base, is a non-nutritive, indigestible, and water-insoluble masticatory solid. It is the core foundational ingredient for gum base-type confectionery such as chewing gum and bubble gum, serving as a carrier for sweeteners, flavors, and other functional substances. According to GB 1886.359–2022 "National Food Safety Standard – Food Additive – Gum Base and Its Ingredients," gum base is defined as a substance prepared by combining rubber, resins, waxes, and other materials for use in the production of gum base confectionery. Gum base ingredients are the general term for food additives including natural rubber, synthetic rubber, resins, waxes, emulsifiers, softeners, antioxidants, preservatives, and fillers, as well as cocoa powder and hydrogenated vegetable oil, used in gum base. Gum base imparts chewing, foaming (bubble-blowing), and plasticizing functions to gum base confectionery and should be discarded after consumption. Gum base must be an inert, insoluble substance that does not dissolve in saliva and does not enter the human digestive system.

Gum base is divided into two main categories: natural gum base and synthetic gum base. Natural gum base primarily uses natural tree gums such as chicle, balata, and jelutong, while synthetic gum base primarily uses synthetic rubbers such as styrene-butadiene rubber, butyl rubber, and polyvinyl acetate. Currently, synthetic gum base accounts for approximately 92% of the global market, making it the absolute mainstream.

The composition of gum base is highly complex and typically consists of the following categories of ingredients:
