History of Chewing Gum

Chewing gum is a type of confectionery traditionally made of chicle, a natural latex product, or rubber.

Chewing gum has traditionally been made from chicle, but for reasons of economy and quality many modern chewing gums use rubber instead of chicle. Chicle is nonetheless still the base of choice for some regional markets, such as in Japan. Chewing gum is a combination of a water-insoluble phase, known as gum base, and a water-soluble phase of sweeteners, flavouring and sometimes food colouring
