This article has a lot of great information on the process of manufacturing HFCS including the use of two enzymes (alpha-amylase and glucose-isomerase) which are genetically modified to be more stable.

“Consumers trying to avoid genetically modified foods should avoid HFCS. It is almost certainly made from genetically modified corn and then it is processed with genetically modified enzymes. I’ve seen some estimates claiming that virtually everything–almost 80 percent–of what we eat today has been genetically modified at some point. Since the use of HFCS is so prevalent in processed foods, those figures may be right.”

Should an ingredient that must go thorugh such a process that includes genetically modified enzymes be allowed in foods labeled “All Natural” or “100% All Natural”.  It’s in “Snapple All Natural Lemon flavored Tea”.  It’s in “Arizona 100% All Natural Green Tea with Honey”, yes the stuff in the Zen-like green can or bottle.
