It turns out that there are, in all kinds of foods, molecules that are called "conjugates." They're a kind of business end of the molecule, and usually attached to a sugar of some kind. When we put something in our mouth, and we have enzymes in our mouth, those enzymes can go to work on things like conjugates and free up the sugar from the rest of the molecule, and the rest of the molecule can be aromatic.
