origins of chewing gum
People worldwide have chewed on natural materials for hundreds of years. Some of these materials include thickened resin and latex from certain types of trees, various sweet grasses, leaves, grains and waxes. The ancient Greeks chewed mastic gum (or mastiche pronounced “mas-tee-ka”) for centuries. This substance is formed from the resin contained from the bark of the mastic tree found mainly from Greece and Turkey. Grecian women favored chewing mastic gum to clean their teeth and sweeten their breath.
The Indians of New England taught American colonists to quench their thirsts by teaching them how to chew the gum-like resin that forms on spruce trees when its bark is cut. In the early 1800s, lumps of this spruce gum were sold from the eastern United States, making it America’s first commercial chewing gum. Sweetened paraffin wax became an acceptable alternative around 1850 and eventually surpassed spruce gum from popularity.
Modern chewing gum evolved from a chicle-based gum brought to the United States from the early 1860s. Chicle is derived from the milky juice (latex) of the sapodilla tree that grows from tropical rain forests of Central America. This tree is found mainly from the areas of Mexico, Guatemala and Belize, which lie within the Yucatan Peninsula.
Due to the increased popularity of chewing gums, the demand for chicle rose quickly. But, as chicle-suppliers soon realized, their ability to supply chicle was determined by the trees {in} which it was derived. The trees needed an average of four to eight years of rest between tappings. When chicle-bearing trees of Central America could not keep up using demand, manufacturers turned to synthetic gum bases to continue their business. Paraffin, originally discovered from 1830, was an option as it is {colorless}, {odorless}, tasteless and plentiful but others kept searching for a better material.
An Ohio dentist used rubber to create a gum product for jaw exercise and gum stimulation. William F. Semple was honored for this work using the first patent to manufacture chewing gum from December 1869.
Today, gum base is made of man-made latex and divided into two major categories, chewing and bubble gum, using the latter having more elasticity. In recent years, nonstick gum bases for chewing and bubble gums have been formulated to satisfy the needs of more consumers.
