Some of it is typical flavoring stuff, onion powder, etc, that could easily show up on a list of spices in a home dish.
But a big part of the list is the stuff you see in highly engineered food product only: maltodextrin, dextrose monohydrate, yellow 5, disodium guanylate, disodium inosinate, sodium phosphate, etc.
No "home cooked meal of home grown fruits and vegetables" has a similar ingredient list to this.
Although I will say that I have suspicions around the industrial processes for food additives and dyes. Yellow 6 for example is petroleum or coal tar derived. I'm sure the relevant regulatory bodies have approved these things, but I am not convinced that it is something I would like to consume personally.
Perhaps the burden should be on the manufacturer? I'm not sure where the discussion would lead if I had to rationalize every industrial by-product I preferred not to eat?
Again, there's no accounting for taste.
