POD turned out to be more resistant to higher pressures than PPO. In turn, the higher temperature of HPP preservation caused a significant decrease in POD activity of 16 to 37%.obtained only a 30% reduction in PPO activity and as much as an 85% lower POD activity in HPP-preserved strawberries
(600 MPa, 60 °C, 10 min). The resistance of strawberry PPO to pressure was also reported by Garcia-Palazon et al. (2004), who achieved complete inactivation of PPO upon pressure treatment at 800 MPa for 10 min.
