Fig. 6.Activity of (a) guaiacol peroxidase (POD) and (b) polyphenoloxidase (PPO) in avocado slices after HPP processing at pressures of 200–600 MPa for 3, 6 or 10 min. The control
treatment is non-HPP treated samples. Values represent average enzyme activity measured from avocados sourced from three growers treated on three consecutive days (replicates).
Error bars represent standard deviation.‘*’ = significant difference from the control atPb0.05
