How chewing gum started ?

You may find many players chewing gum on the field. Studies suggest that chewing gum can increase concentration. Some chew gum for the flavor and fun Even before the kind of gum we know today, people enjoyed chewing on different things. Greeks used to chew a special kind of tree sap. Native Americans and the Mayans had their own versions of gum. They would chew on the sap from specific trees. These early forms of gum set the stage for what we enjoy today.

What's in our gum: The gum base?

Now, let’s talk about what makes up our modern-day gum. The first important part is called the “gum base.” The gum base is what gives gum its chewy texture. It’s a mix of materials like resins and waxes .

 

Resins are a sticky kind of material that has a bit of stretch. They’re a big part of what makes gum stay chewy for a long time. The waxes, on the other hand, keep the gum from getting too hard. They make sure it stays soft enough to chew.

Adding taste to gum: Sweeteners and flavors

Just the gum base alone wouldn’t be very tasty. That’s where sweeteners and flavors come in. Sweeteners are what make the gum sweet. They could be simple sugar or something else called xylitol.

 

Flavors make the gum taste like something specific. These flavors could be anything from mint to fruit or even cinnamon. Some kinds of gum also have a liquid center that gives extra flavor as you keep chewing.

How is chewing gum made?

Making chewing gum is a process with several steps. First, the gum base is heated until it turns soft. In the early days (as early as the Stone Age!), chicle gum was made from the sap of a tree called Sapodilla.


Modern methods make use of a rubbery chemical called polyisobutylene. This is mixed with other chemicals, called plasticisers, to make the gum chewy. It is very important to know that these items may or may not be fit for chewing on, as these are synthetic chemicals. Hence these are called food grade chemicals, which are safe to consume.


Next, the sweeteners and flavors are mixed in with the base. This creates a big lump of gum mixture.


Then, the gum mixture is rolled out until it’s flat. After that, it’s cut into the right shape. That’s how you get your square, circle, or rectangle gum pieces. The last step is to wrap each piece of gum and put them into packages. That’s the gum that you see on store shelves.

Why is chewing gum so flexible?

Both chicle and polyisobutylene have a narrow temperature range over which they start to soften. This comes in handy because the chewing gum needs to stay firm and tough inside the package, however, the subtle change in temperature can change the chewing gum into a flavorful delicacy. The warmth provided by our mouth softens the gum.

Fun facts: What you didn't know about gum?

Chewing gum has a long history and it’s something that many people enjoy. Here are some fun facts about gum that you might not know. Did you know that the average person in America chews around 1.8 pounds of gum every year?


Also, the largest bubble ever blown from gum was 20 inches across. That’s almost two feet wide! Can you imagine a bubble that big?


How gum has gone from being tree sap to the tasty treat we have today, is a story of humane genius.
