What Is Gum Really Made Of?

Chewing gum is a confectionery product made from a combination of several ingredients that give it its characteristic texture and flavor. At its core, gum is primarily composed of a gum base, which provides the chewy consistency. Traditionally, this gum base was derived from natural latex substances like chicle, a sap from the sapodilla tree found in Central America. However, most modern gums use synthetic rubber-like materials such as polyvinyl acetate or polyethylene to achieve a similar effect. These synthetic bases are more cost-effective and offer consistent quality. In addition to the gum base, chewing gum contains sweeteners, which can be sugars like sucrose or glucose, or sugar substitutes such as sorbitol, xylitol, or aspartame for sugar-free variants. Flavorings are also essential and can range from natural extracts like mint and fruit to artificial flavors. Softening agents, such as glycerin or vegetable oil, are added to maintain moisture and ensure that the gum does not become too hard. Finally, food colorings are often used to enhance the visual appeal of the gum. The combination of these ingredients is what makes up the familiar, enjoyable experience of chewing gum.

The natural origins of gum

The earliest forms of gum were entirely natural and derived from trees that were indigenous to ancient cultures. The oldest known chewing gum is believed to be birch sap; a piece of birch bark sap with bite marks was found in Finland and is estimated to be between 5,500 and 6,000 years old.

In Greece, a natural gum was sourced from the mastic tree on the southern island of Chios, dating back 2,500 years to the era of Hippocrates. In the Mayan and Aztec civilizations, which spanned from Mexico to Central America, the sap from chicozapote trees was collected, processed, and chewed. Native Americans also chewed on hard sap nuggets from spruce trees, which eventually led to the creation of the first commercial chewing gum in the United States.

If you prefer not to use the popular synthetic gums available today, you can enjoy gum similar to that of the ancient Mayans and Greeks. In Mexico and parts of Central America, there are still producers known as chicleros who gather the white sap from tree trunks, cook it down, and shape it into large blocks of natural gum. This product, called chicle (the Spanish word for gum), is distributed to over 30 countries worldwide. The teardrop-shaped sap drippings from the mastic tree are still collected and sold for chewing. While natural gums may be harder to find in typical supermarkets, they can be purchased online or at select natural food stores.
