Just came across this article because I know that many food manufacturers use different names for MSG like substances in foods but this article really explains yeast extracts and the like. If your package lists 'spices' as one of the ingredients don't eat it or inquire what that 'spice' is. I think you will be happy/surprised/maybe not-so-happy you did.
Scary, but worth the read because knowledge is power.
