Why do flavors “hit” at different times in our mouth?

Question

Such as when eating something hot, you get the sweeter notes first, before the heat.

In: Biology

Answer 1

The flavors are already there. The sweetness is noticed first because of dopamine and once it wears off, you are accustomed to the heat. Also, the heat from spices is a pain sensation that does not get noticed as fast as the taste sensation because of the wiring of the brain.
