This study aimed to investigate the staged application of ultraviolet C (UV-C) radiation on some qualitative and phytochemical characteristics of strawberry fruit cv. Paros during 14 days storage at 4°C and 85-90% relative humidity. The experimental design was a factorial based on a completely randomized design with two factors: the first factor was UV-C radiation (single-phased, dobuble-phased, and multi-phased UV-C radiation at an intensity of 4 kJ/m²), and the second factor was the storage period (0, 7, and 14 days) with three replications. The results showed that at the end of the 14-day storage period, multi-phased UV-C radiation showed 55.17% and 72.73% less weight loss and decay compared to the control treatment, respectively. This treatment also better maintained firmness and titratable acidity by 148% and 64% compared to the control, respectively. There was no significant difference in pH among the UV-C treatments at the end of storage, but they were higher than the control. At the end of the storage period, the multi-phased UV-C treatment increased the content of vitamin C (61.65%), total phenol content (49.44%), and antioxidant activity (22.92%) compared to the control. Single-phased UV-C radiation increased the total flavonoid and anthocyanin content by 51% and 111% more than the control on the 14th day of storage, respectively. Overall, multi-phased UV-C radiation had the greatest impact on increasing bioactive compounds and maintaining the quality of strawberry fruit, followed by the double-phased UV-C treatment, which showed more positive effects than the single-phased treatment.
