Is food flavor 90 percent bacterial?

I’m riffing on the commonplace of human biology that the human body is actually 90 percent bacterial cells.

Well, if not 90 percent, bacteria on at least some foods contribute to the food’s flavor and odor. Those foods include, so far, grapes, onions and bell peppers.

And, given what I said about the human body, and how we know bacterial action contributes to human body odors, I’m sure we’re scratching just the surface of this scratch-and-sniff iceberg.
