How is Chewing Gum Made
Sunday, November 9, 2008
All formulas for chewing gum manufactured today share the same main ingredients: a gum base, sweeteners, chiefly sugar and corn syrup, and seasonings. Some also contain softeners, such as glycerine and vegetable oil. The quantity of each added to the mix varies as to which type of gum is being constructed. For example, bubble gum contains more of the gum base, so that your bubbles don't burst…particularly during class!Though gum producers cautiously guard their formulas, they all share the same basic process to reach the completed product. Preparation of the gum base at the factory, by far the most extended step, necessitates that the raw gum stuffs be melted down and sterilized in a steam cooker, and then pumped to a high-powered centrifuge to rid the gum base of unsuitable dirt and bark.
Once the factory workers cleanse the melted gum base, they blend approximately 20% of the base with 63% sugar, 16% corn syrup, and 1% flavoring oils, such as spearmint, peppermint, and cinnamon. While still hot, they run the mixture between pairs of rollers, which are coated on both sides with fine-grained sugar, to prevent the resulting ribbon of gum from sticking. The final pair of rollers comes fully outfitted with knives, which snip the ribbon into sticks, which yet another machine singly wraps.
The gum base used in these recipes is, for the most part, constructed, due to economic constraints. In the good old days, the entire gum base came straight from the milky white sap, or chicle, of the sapodilla tree found in Mexico and in Guatemala. There, indigenes collect the chicle by the bucket, boil it down, mold it into 25-pound blocks, and ship it straightaway to chewing gum factories. Those with little or no self-restraint, chew their chicle directly from the tree, as did New England colonists, after watching Indians do the same.
The concept of chewing gum stuck, and continues to play a vital role in our economy, mostly due to the many benefits associated with its use. Sales of chewing gum first began in the early 1800s. Later, in the 1860s, chicle was imported as a replacement for rubber, and finally, in approximately the 1890s, for use in chewing gum.
The pure delight derived from angering a schoolteacher by blowing bubbles in class, or from bothering a co-worker by snapping it, is only one of the attractiveness of chewing gum. Chewing gum really helps to clean the teeth, and to humidify the mouth, by stimulating saliva production, which helps to neutralize tooth-decay-forming acids left behind after eating hard food.
The muscular action of chewing gum also helps to check a person's appetite for a snack or for a cigarette, to focus, to stay awake, to ease stress, and to relax one's nerves and muscles. For these very reasons, the armed forces furnished soldiers with chewing gum in World War I, World War II, in Korea, and in Vietnam. Today, chewing gum is still included in field and battle rations. In fact, the Wrigley Company, following the Department of Defense specifications supplied to government contractors, issued chewing gum for the distribution to troops stationed in Saudi Arabia during the Persian Gulf War.
