What is gum made of?

Gum has some main ingredients, which are:

  • Gum base. Is the main ingredient for chewing gum, is responsible for the chewable feature, and also helps soften the gum and add flexibility to the mixture. Is made of resin, wax, and elastomer.
  • Sweeteners. This is the ingredient that adds that sweet flavor to gum. Some ingredients used as gum sweeteners are:

  • Mannitol
  • Sorbitol
  • Softeners. They are added to increase flexibility and keep moisture, basically, it is responsible for the experience of chewing gum texture. Some ingredients used are glycerine and vegetable oil.
  • Flavorings. We all know gum is present in every possible flavor, but at the end of the day is the factor that catches the eye’s attention. The most popular ones are peppermint and spearmint.

Gums are products that do not need to specify the expiration date on the label of the product. The gum’s components are water-free, which means no bacteria can grow in that environment. Some brands like Trident do include the expiration date on the label of their products.

 Although most gums do not have an expiration date, this does not mean their texture and flavor will remain the same as time passes. Most times, when the gum is consumed after the expiration date, some changes can be noticed.

Sugary gum is more likely to grow some bacteria or lose its features sooner, and that is because of its composition and added ingredients.
