Can someone please explain to me why it is that the organic Gerber baby food has so many random ingredients, and the non-organic does not?

I started out making Graciela’s baby food. However, sometimes we don’t eat anything for dinner that I can just mash or put in the food processor for her. So I figured I needed some backups for such times. I’ve been trying to stick to things that don’t have tons of preservatives in them, because I really don’t see why a baby should have that kind of junk in their system, but this is baffling.
