No significant changes (p < 0.05) in physicochemical properties, nutritive value or sensory attri-
butes were detected in the treated apple juice, but the PPO started recovering its activity during the
storage without causing significant difference (p < 0.05) in its colour. PME was completely inactivated in
the HPP treatment, while indigenous micro-biota of the raw juice was also eliminated. The applied
processing conditions preserved the physicochemical and sensory quality of apple juice, and kept
polyphenols content and antioxidant capacity unaltered
