I've heard the claim that artificial banana flavoring doesn't taste like bananas since it was based on a different cultivar than the one we know today. Until the 1950's the main banana cultivar commercially grown and sold was the Gros Michel or Big Mike. This would be the banana most people were familiar with. However, the Gros Michel was nearly wiped out by Panama Disease, so bananas you find in the stores today, are mostly all of the Cavendish variety, which can withstand the disease.
I've read and heard the claim that the artificial banana flavor used in candies and other food, is based on the taste and flavor of Big Mike. That, according to the claim, is the reason that banana flavored food tastes nothing like bananas. See for instance this article in Business Insider: "Strange Facts About Bananas".
In a thread on the Snopes forum someone offers the idea that the difference in taste is more likely due to use of a single flavoring, isoamyl acetate, instead of a richer palette of flavorings. But that doesn't exclude the possibility that the artificial banana flavoring was developed in the time of Gros Michel and based on its taste, and has changed little since, possibly because it became a flavor in its own right.
So, is the taste of artificial banana flavor more like the Gros Michel than the Cavendish?
And if so, is that because artificial banana flavor was developed to taste like the Gros Michel?
