To make chewing gum, gum base is melted and purified, and then it is mixed with flavors and sweeteners before being rolled into a loaf of gum that goes through a series of rollers, according to Wrigley. After passing through the rollers, it is coated with sugar or artificial sweetener and then scored into sticks, strips or tabs; the gum is then conditioned, broken, coated, sprayed with a spray dryer and tumbled in a syrup mixture before it is wrapped with the help of a wrapping machine and then packaged in blister packaging or other types of packaging for shipment to distributors.Continue Reading
Up until the middle of the 19th century, chewing gum was made using a substance called chicle that is derived from the latex sap of the sapodilla tree. This tree is native to Central America, and the sap is a form of rubber. The chicle was mixed with flavorings to create gum. Much like a rubber band, chicle does not dissolve when it is chewed, although it is softer than a rubber band.
Chemists learned to make artificial gum bases by the 1960s, and these replaced chicle. Although they have the same temperature profile as chicle, these bases are synthetically produced.Learn more about Candy
