TL;DR: everything in the middle of the grocery store has altered tastes, chemically, to make you eat and buy more of it.
The sad reality is that nature sucks. When you want a specific fruit, vegetable or animal-sourced flavor it's never going to be the same twice. The large OJ bottlers, for example, are always blending juice from a variety of sources to get the right level of sweetness/acidity but even then it's always going to differ. When you're adding just a little bit of an ingredient it's that much harder to make sure you get exactly the right qualities in every batch and that's where these guys come in. Every manufacturer strives to get you to buy more; there's nothing magical about what these guys do, they just assure the consumer that the flavors you liked last time will be replicated effectively the next time you buy, but there's no mystical "make you eat more" ingredient in there.
