Answers<br />
Chewing gum is made with three basic ingredients:<br />
gum base,<br />
sweeteners, <strong>and</strong><br />
flavourings.<br />
The main ingredient of chewing gum is the gum<br />
base, which is like rubber. It makes the gum chewy<br />
<strong>and</strong> also gives it a smooth texture. When chewing<br />
gum was first produced, gum base was made from tree<br />
sap, but now artificial gum bases are used. As the<br />
gum base gets warm in your mouth, it softens <strong>and</strong><br />
the flavour of the gum is released. Sweeteners <strong>and</strong><br />
flavourings are added to the gum base. The most<br />
common sweeteners added to chewing gum are<br />
sugar <strong>and</strong> corn syrup. The most popular flavourings<br />
used in chewing gum are peppermint <strong>and</strong> spearmint.<br />
