Oh, bullshit.
Cane sugar has a very different mouth feel than HFCS. Itโs completely obvious if you taste the two around the same time.
Yes, I realize there is no โobjectiveโ taste of anything, but I also think nearly all of those tasting studies are hopeless flawed as people do taste and experience things subjectively, so attempting to make them do so objectively is kind of like asking a Geiger counter, โIf there were some radiation here, how much radiation would there be?โ
Itโs an example of science extending itself into areas where it has no dominion and is also often conducted by people so disconnected from the actual world that they donโt even understand what it is that they are testing โ thus their conclusions are completely wrong.
And donโt tell me mouth feel doesnโt matter. Try tasting soy nog and egg nog back to back. Even if all the ingredients that constitute the actual flavor are the same, mouth feel is what makes them (mainly) differ so much.
(If you think mouth feel doesnโt matter, why do you not blend all your food and drink it? After all, itโd be just the same that way.)
