Why do baked tostitos get warm when you chew them?Anybody else notice this? I don't see anything in the ingredients that would likely cause a noticeable exothermic reaction with saliva....maybe I'm just weird.
...time passes...
Upon further consideration... my best guess is that it is a mechanical effect caused by the particles of corn crunching against each other. You would get the same effect in any other corn chip, sure, but Baked Tostitos have very little fat, and so little place for the heat to go in those high-friction movements. Perhaps the fat in corn chips acts as a lubricant for the corn particles.
Though, I'm sitting here with a piece of a chip just in my mouth, not chewing...and it's getting a little warm, but not as warm as it does if I chew. So maybe it has two causes.... wow this is a dull day at work, huh?
