I read here about Bare apple chips being legal, so i looked into their other fruit and vegetable chips. I inquired about any unlisted ingredients/ processing aids and was told that there are no unlisted ingredients or processing aids for any of their chips, besides a select few, which only have sunflower oil added, which is legal.
So really, you can look at the ingredients on the chips and determine if that type is legal-and many are. Their website is baresnacks.com
Im attaching the email they sent me
