Structure[edit]

what is the structure of polyphenol oxidase??


Food browning[edit]

This article mentions tea and coffee are a result of PPO, but the article on Maillard_reaction implies the opposite. I would think roasting coffee would be in the realm of a Maillard reaction instead due to the intentional heating, which would likely inactive the PPO enzyme in the process anyway. Can another shed more light on this subject and/or comment if that line related to tea and coffee should be removed? Bobtheowl2 (talk) 16:17, 23 July 2012 (UTC)
