What is the chemical reaction that causes “heat” when eating a pepper?
In: 10
It’s not really a chemical reaction that releases heat. Rather the capsaicin in pepper is an irritant. In repsonse the body duakites blood vessels in the mouth and nose making our mouth and nose feel hotter. Just like how a fresh bruise or cut will feel slightly hot to the touch and swell. Essentially the spicy flavor is a “pain” reaction.
