Have you ever wondered why popping a Mentos candy in your mouth gives you an instant cooling sensation? The secret behind this phenomenon is our classic homie, menthol. Menthol has the fascinating ability to activate a specific type of receptor in our sensory system. In this blog post, we’ll explore the science behind that refreshing cool feeling.
Fun Fact: Hensel and Zotterman discovered this for you, but it took more than 50 years to believe them.
The Cool Activation
When you consume a Mentos candy containing menthol, this chemical interacts with the TRPM8 receptors on the sensory nerve endings in your mouth. These receptors are like tiny gatekeepers that respond to various stimuli, including cold temperatures and certain chemical compounds, such as menthol.
As menthol binds to the TRPM8 receptors, it triggers a series of events that lead to the activation of these receptor channels. Think of it as unlocking a door and allowing ions, like calcium and sodium, to flow through. This influx of ions generates electrical signals, which are then transmitted to your brain, resulting in the perception of a cool sensation.
TRPM8 Receptors: The actual “COOL”
The TRPM8 receptor is primarily known for its sensitivity to cold temperatures. Just like dipping your toes in a chilly stream on a hot summer day, the activation of TRPM8 receptors by menthol tricks your brain into perceiving a refreshing coolness. It’s like a burst of icy freshness on your tongue.
But here’s the interesting part – menthol doesn’t actually change the temperature of your mouth. It simply stimulates the TRPM8 receptors, which are normally activated by cold temperatures. By activating these receptors, menthol creates a perception of coolness without any actual temperature change. It’s like a sensory illusion, fooling your brain into thinking it’s experiencing something cold.
Mentos candies, with their menthol content, offer more than just a burst of flavour. The menthol activates the TRPM8 receptors in your mouth, triggering a perception of coolness that refreshes your senses. By understanding the science behind this fascinating phenomenon, we gain a deeper appreciation for the intricate workings of our sensory system.
So, the next time you enjoy a Mentos candy and experience that instant cooling sensation, take a moment to appreciate the remarkable role played by menthol and the TRPM8 receptors in creating a refreshing experience that tantalizes your taste buds and leaves you feeling pleasantly cool.
