Who invented it?

Archaeologists have found that long before the historical records, human ancestors loved to chew natural resin for fun, which is the most primitive "chewing gum". For thousands of years, people from different regions and cultures have the habit of chewing gum. For example, the ancient Greeks cleaned their teeth with resin to keep their mouths fresh, the Indians loved to chew the sap of tree trunks, and the Mayans in Central America loved to chew gum.

There is a deep affection between the United States and chewing gum, not only because chewing gum is one of the important export products of the United States, but also the pride in the history of American invention. The chewing gum we ate today can be traced back to 1848. At that time, John Curtis of the United States made the first piece of chewing gum for sale and processing. 1869, photographer Thomas Adams made the first chewing gum product made of chewing gum. The following year, he introduced a kind of chewing gum "Black Jack" flavored with licorice essence, and changed the chewing gum from block to strip, which was very popular and can still be found in the market.

1906 invented chewing gum, but the first kind of chewing gum was too sticky to sell. Until 1928, the technology of making chewing gum was finally perfected and successfully entered the market. The first batch of chewing gum was pink and named "Dubble Bubble". Sugar-free chewing gum came out in the 1950s. Today, the main materials for making chewing gum are sugar, syrup, seasoning, softener and gum base.

Chewing gum was invented by Americans, and Americans love chewing gum. According to statistics, the chewing gum that Americans chew every year can be as long as 5 million miles if it is connected in a line. It is said that during World War II, chewing gum was a munitions of the United States, and it was supplied in large quantities to American troops on the battlefield, because people thought that chewing gum could ease tensions.

The earliest chewing gum in the world is refined spruce chewing gum from Maine, USA. 1848, John Catches of Maine made chewing gum from spruce. However, chewing gum made of sugar gum did not appear until the 1970s. Surprisingly, the invention of this kind of chewing gum is actually related to photography, which is a typical story of waste utilization.

Thomas Adams is the owner of a photo studio in Staten Island, USA. 1870, he intended to improve the molding material of photographic film, so he tried to replace rubber with sugar glue, but failed. One day, he accidentally put some useless sugar gum in his mouth and chewed it. At this moment, he had a brainwave: if this kind of chewing gum is spiced, isn't it also chewing gum? He asked the predecessors of spruce gum, but they all thought that it was not appropriate to take risks and that the failure of spruce gum could be regarded as a warning. But he wouldn't listen to dissuasion. After two years of research and development, he finally established a factory in 1872, and achieved success.

Wave-blowing gum actually evolved from chewing gum.
