Browning degree, changes in color, total phenol content, superoxide
anion production rate (O2
), H2O2 content, antioxidant capacities (DPPH radical scavenging ability, ABTS
radical scavenging activity and the reducing power) and activities of the phenol metabolism-associated
enzymes including phenylalanine ammonialyase (PAL), catalase (CAT), peroxidase (POD), polyphenol oxidase
(PPO) were evaluated.
