I LOVE banana flavored stuff. When I say this, people will often say "even banana flavored Laffy Taffy?". Yes, that's the best flavor and it's not even close.
That flavor is isoamyl acetate and the original "Big Mike" bananas of yesteryear were rich in it. Seriouseats actually has a really good article on it. I'm right there with you though. I actually love the flavor too. More for us, friend.
They still exist but they aren't bred at scale anymore.
A lot of the suitable land for the banana is contaminated with the fungus that causes Panama Disease so they can only be planted on land without it.
A decade ago, a new strain of the fungus that infects Cavendish was detected. There isn't any real replacement or treatment for it yet, meaning there is a high chance that all edible bananas will go extinct.
I like bananas, but I definitely don't like banana flavored stuff. So I guess you might be right. It tastes so artificial imo. When we buy yoghurt, the banana yoghurt is always the one that stays until all other flavours are gone. Same for candy.
That's because it doesn't taste like the bananas we eat nowadays. It's a flavor based on the Gros Michel banana, which was largely wiped out in the 1960s by a disease. The bananas we eat today are less flavorful, but they're also resistant to that disease.
