Abstract
The changes in antioxidant enzyme activity and oxidative enzyme, polyphenol oxidase enzyme (PPO) in strawberry fruit (Fragaria x ananassa cv. Camarosa) illuminated with different UV-C dosages were investigated. Three UV-C illumination dosages 0.25, 0.5 and 0.75 kJ/m 2 tested, promoted antioxidant enzyme activity and reduced oxidative enzyme, polyphenol oxidase, activity at 10 o C compared to the control. UV-C radiation for 0.5 and 0.75 kJ/m 2 showed the best results for enhancing antioxidant enzyme activity including superoxide dismutase (SOD) and catalase (CAT), also decreasing polyphenol oxidase activity. All UV-C dosages enhanced antioxidant enzyme activity and reduced, polyphenol oxidase activity but 0.75 kJ/m 2 UV illumination gave the best results.
