What is the source of chewing gum?

The production of chewing gum was first related to a Mexican general named Antonio Lopez de Santa Ana. 1836, he was captured in the Battle of Jesento and released back to China by American general Sam Houston. Soon, Santa Anna came to new york with a heartwood chewing gum, which grew in the jungle of Mexico and was chewed by Aztecs (Mexican Indians). As for why Santa Anna brought this gum to the United States, there are many theories at present. One view is that Santa Anna wants to arouse the interest of some American adventurers in this kind of chewing gum and replace it with rubber; Another view is that it is only because he likes to chew this kind of gum. Despite different opinions, he did take this bag of chewing gum to see Thomas Adams, an adventurer in Jersey, USA. Later, the experiment of replacing rubber with this chewing gum failed, and Santa Anna ran away in debt.

When talking with Santa Anna, Adams found that Mexicans took a small piece of chewing gum from their pockets from time to time and put it in their mouths to chew. Adams' son Horatio likes it, too. One afternoon, Adams saw the shopkeeper selling a piece of paraffin to the little girl in a drugstore. At that time, paraffin was used for chewing. This reminds Adams of Santa Anna's chewing gum and his son's interest. He asked the drugstore owner if he would like to sell a better chew, and the boss immediately agreed.

Adams and his son Horatio are at home processing chewing gum brought by Santa Anna. By the way, Horatio 1956 died at the age of 102, which may be related to his habit of chewing gum. Father and son add hot water to the chewing gum, stir it into a sticky shape, then rub it hard, and finally knead it into a ball. Adams sent these balls to the drugstore. A day or two later, the boss told him that these rubber chewing gum sold well for a penny.

Adams bought another batch of chewing gum for $55, rented the floor of a factory in Jersey City and started mass production. The chewing gum he produced has no strange taste. Later people called it: Adams's new york gum-loud and soft.

Adams' other son, Thomas, shipped chewing gum to Mississippi in the west to sell it. Although some people shouted that it was a "bad habit" at that time, snuff smokers and smokers dismissed it as a "woman's chew", parents tried their best to prevent their children from buying it, and teachers also regarded it as a serious confrontation with the classroom, but it didn't help.

Some people fabricate scientific evidence that chewing gum is made of horseshoe and glue, which will not only lead to indigestion, but more seriously, if it is swallowed carelessly, it will lead to appendicitis in light and intestinal adhesion in severe cases. Hundreds of children have been waiting for death because they accidentally swallowed chewing gum. As a result, death did not befall them. 1932, nikola tesla, an electrical expert, asserted that "chewing gum will lead to salivary gland failure and death." However, five years ago, James Dowkat told the American Medical Association that the boxer Jack Dempsey had the habit of chewing gum, which made his jawbone so strong that when Georges Carpentier hit his jawbone, his jawbone was intact, but Carpentier broke his thumb.

Adams's new york gum was loud and soft. After it was a great success, he tried to add some spices. He first tried sassafras oil and licorice, and called licorice-flavored chewing gum "Black Jack", which is the oldest flavored chewing gum on the market at present.

Since then, chewing gum production has flourished, and more and more people chew gum. 1875, John Colgan added aromatic agent to chewing gum, which added a large number of lovers to chewing gum. It was not until 1880 that someone added mint to chewing gum that the output of aromatic chewing gum fell from its peak.

The production of chewing gum has made many people rich and become millionaires. William Jay White used to be a popcorn vendor. Because of an accident, the seller sent the chestnuts he ordered into chewing gum. As a result, he mixed corn syrup with chewing gum and added spices to make a good chewing gum. This process is simple and low-cost, which makes White become a millionaire, build a manor and be elected as a member of parliament.

Until World War II, the most basic raw material of chewing gum was chewing gum. Heart fruit trees are wild in Central America, South America and the Amazon River basin. Only 70-year-old trees can be cut down. Cut down a tree every five years, and only during the day. Because of the war, the source of chewing gum is very difficult. Moreover, most chewing gum is supplied to the army, so chewing gum has become a scarce material. Soldiers chew gum to relieve tension and fear, moisten their throats during long marches, and sometimes even use it to repair jeep tires, fuel tanks and aircraft parts. In order to overcome the shortage of chewing gum, people began to test the synthetic main agent and synthetic resin of chewing gum, and found that the quality control of synthetic resin is easy, even if people swallow it, it is completely harmless. Most chewing gum people chew today is based on polyvinyl acetate. Until recently, manufacturers began to be cautious about promoting the use of synthetic resin as raw materials, because people think that chewing gum made of gum collected from mysterious virgin forests is more romantic.

The production of chewing gum also provides some employment opportunities for the service industry, and chewing gum cleaners are employed in theaters, hotels, churches, restaurants and other public places. In the center of new york, a man cleans chewing gum at the central station of new york subway. He cleans up 7 kg of chewing gum every day, which is as high as 14 kg on weekends. Some authorities have publicly instructed chewing gum manufacturers to bear the cost of removing chewing gum from the subway. As a result, the larger manufacturers printed the words "Please wrap the chewed chewing gum with sugar paper" on the wrapping paper, but no one obeyed.

Why do people like chewing gum? Psychologists have three reasons to analyze. First, eliminate loneliness and irritability; Second, ease the tension; Third, vent your inner anger by chewing. Whether the explanation is correct or not, people just like it.
