Over time, lollipops have had different looks. They have been traditional hard candy on a stick and hard candy on a ring, some include bubble gum or chocolate as a surprise center and some even spin or glow. Whether traditional or novel, the lollipop is still enjoyed by many people.
The History of Bubble Gum
There is evidence that the early Greeks chewed on a substance made from a resin of the mastic tree indigenous to Turkey. In North America, Native Americans chewed on a substance that was made from the resin of spruce trees. This practice continued until the early 19th century and has been accredited as one of the first modern examples of chewing gum. In the late 19th century, paraffin or edible wax was introduced as a substitute for spruce resin. Although this trend was short lived, we do see similar examples in modern candies such as wax fangs or wax lips or the retro candy classic, wax bottles. Although flavors vary, all chewing gum consists of basic ingredients. The base is often made from resins from tropical trees as well as synthetic materials such as polyvinyl acetate, wax or rubber byproducts. The remainder is an amalgamation of corn syrups, sugars and hundreds of flavorings not to mention artificial colors. The base is melted to a soluble liquid and then combined with the byproducts and stored in a solid block. It is then combined with colorings, flavors and sweeteners prior to packaging. Bubble Gum, unlike regular chewing gum, has a base that consists of rubber latex and this is what gives it elasticity.
Early chewing gums were a challenge as they were hard to chew and the flavor, if any, lasted a very short time. As chewing gum became more popular, manufacturers began to experiment with new flavors and non-solid, often liquid, centers. The advent of modern chewing gum is attributed to Mexican General, Antonio Lopez de Santa Anna, who became infamous as one of the participants of the Alamo. As with most great inventions, it was more luck than planning.
After being exiled from Mexico, he introduced Thomas Adams Sr. to Chicle which is a substance derived from Sapota or Saodilla trees. Adams wanted to use the elastic ingredient in experiments to find ways to make more economical car tires. Although he was never able to produce an economical tire substitute, in the end, he created one, if not the, first mass marketed chewing gums called Adams New York Chewing Gum. The first patent for chewing gum was awarded in 1869 although Adams did not create the first mass production chewing gum assembly line until 1871.
In 1880, William White combined corn syrup with Chicle and added peppermint extract thus creating the first flavored gum called “Yucatan”. In the same period, Dr. Edward Beeman added pepsin powder and created a gum that was to serve as a 'digestive aid.' Beemans Chewing Gum, still available today, is a derivative of this discovery.
