How was chewing gum invented?

Did you know that chewing gum is one of the oldest candies in the world? Archaeologists have discovered that long before historical records began, human ancestors loved to chew natural resin for fun. This was the most primitive "chewing gum". For thousands of years, people from different regional cultures have had the habit of chewing "glue". For example, the ancient Greeks used resin to clean their teeth and keep their mouths fresh, the Indians liked to chew the sap from tree trunks, and the Mayans in Central America liked to chew chicle. The United States has a deep affection for chewing gum, not only because chewing gum is one of the important export products of the United States, but it is also a pride in the history of American invention. The chewing gum we eat today can be traced back to 1848. At that time, John Curtis in the United States produced the first chewing gum for sale and processing. In 1869, photographer Thomas Adams produced the first commercial chewing gum made from chicle gum. The following year, he launched "black jack", a chewing gum flavored with licorice extract, and changed the chewing gum form to sold in strips. It became so popular that it can still be found on the market today. Chewing gum was invented in 1906, but the first type of chewing gum was too sticky and could not be sold. It was not until 1928 that the technology for making chewing gum finally improved and successfully entered the market. The first chewing gum was pink and called "dubble bubble." Sugar-free chewing gum was launched in the 1950s. The main materials used to make chewing gum today are sugar, syrup, flavorings, softeners and gum base.

In Mexico, people have had the habit of chewing the sap of wild pear trees since ancient times. In 1860, Adams of the United States solidified the sap and sold it, naming it [jikulu] (meaning to chew); then he named Jikulu After the odor of gum was eliminated, it was renamed Adams gum and sold in large quantities; in 1880, Rigre of the United States added sugar, mint, etc. to the gum to create fragrant and sweet chewing gum.
