No, gum doesn't expire in the sense that it becomes unsafe to consume. However, its quality deteriorates over time.
What Happens to Gum Over Time?
According to the International Chewing Gum Association, gum is a very low-moisture, non-reactive product that won't deteriorate in a way that poses a health risk. [12-Feb-2024] While not inherently dangerous, its properties change. Over time, gum will:
- Lose its flavor: The flavorings will fade, resulting in a less enjoyable chewing experience. This can happen relatively quickly, even within a short time after opening the package, as noted in a Reddit discussion. https://www.reddit.com/r/NoStupidQuestions/comments/17il7on/does_gum_really_expire/
- Become hard and brittle: The texture will change, becoming less pliable and more difficult to chew. https://www.quora.com/What-happens-if-you-eat-expired-chewing-gum
- Maintain its shelf life for years: Properly stored gum can last for two years or even longer. https://usa.inquirer.net/120245/does-gum-expire-what-you-should-know
"Expiration Dates" on Gum
Dates printed on gum packaging are often "best before" dates, not true expiration dates. These dates indicate when the gum is expected to be at its best quality in terms of flavor and texture. https://www.quora.com/What-are-the-risks-of-eating-expired-gum Gum isn't legally required to have an expiration date in most places because it doesn't pose a health risk even after a significant amount of time. https://spoonuniversity.com/lifestyle/does-gum-expire/
