I’m only going to partially agree with that. Things like Nerds or Mt. Dew have no real precedence of what they should taste like. I agree that changing the formula may make the taste change slightly and that is possibly noticeable by regular consumers, but I don’t believe there is a default taste for any of these artificial foods. I think the old school partially hydronated peanut butter JIF taste better than anything today. Now is there any truth in that, or is it just good old rosy nostalgia? There are people who tell me they can taste the difference in caffeine free soda (not diet)…I doubt I could in a blind taste test. If I never had ripe tide rush Gatorade would it matter if it was blue or clear?
I know what you are saying. Take a look at cocktail cherries:

An organic version is typically dark red because the coloring is derived from beets (or other food stock), while those bright red ones on the right are colored with red40. From a purely visual aspect the bright red ones look more appetizing than the dark red ones.
