Thing I learned about bubblegum

So, what IS that distinctive bubblegum-like smell and flavor? What is it made of, and what is it supposed to be?

It's a simplified artificial strawberry flavor/scent plus a simplified artificial banana flavor/scent. It makes me wonder if it would be possible to do something with actual strawberries and bananas to play off of that, but I suspect not. Real strawberries and real bananas are far to complicated -- and I think that the artificial banana flavorings are based off of the might-as-well-be-extinct Gros Michele banana, rather than the modern Cavendish, so, unless I got my hands on enough Gros Micheles to experiment with, I'm never going to find out.
