5. ( Polyphenoloxidase is involved in the darkening of wheat products due to its oxidative effect on endogeneous phenols. Darkened wheat products are unacceptable to consumers, and there has been a considerable effort to reduce genetic levels of PPO activity in wheat germ plasm. a. Briefly describe the browning reaction in the bran layer of wheat that is catalyzed by polyphenoloxidase using phenol as substrate.
