I mean that would seem to apply to nearly all packaged foods that aren't plain bagged fruits and vegetables. If you sell food, you want it to taste good and want people to want to eat more of it. Whether its doritos, chili dogs, apple pie, bread, jam, or whatever else. Nobody makes a mix of peanut butter, finds it bland and unappealing, but then doesn't change either the ingredient proportions, ingredient sources, or add in other flavors or spices or sugars to make it more appealing.
