Effect of low intensity direct-current electric field on anti-browning of apple juice: Enzyme inactivation kinetics and juice properties

For the first time, the efficacy of low intensity (1–7 V/cm) direct-current (DC) electric field in preventing browning in apple juice is examined. The results show that applying a 5 V/cm electric field can inactivate 89.24% of polyphenol oxidase (PPO) within 90 min and achieve complete inactivation...
