Assume you have been chewing a piece of bread for 5 or 6 minutes. How would you expect its taste to change during this interval? Why?

It should begin to taste sweet because the amylase changes the flour's starch into sugar. Starch is just long chains of sugar molecules.

It loses its sweetness. Salivary Amylase is an ezyme that breaks down starch: starch is a long chain or simply monomers of glucose... but the bread also has simple sugars in it, and they are the easiest, and therefore fastest to break down.. so the cookie, cracker or bread goes from tasting sweet or at least semi-sweet.. to very much bland and maybe even a little sour by the end of the timespan.
