Effects of X-ray irradiation on the postharvest quality characteristics of ‘Maehyang’ strawberry (Fragaria × ananassa)

•Effects of X-ray irradiation on postharvest storage of strawberries were evaluated.•Irradiation (≤1 kGy) reduced fruit weight loss and decay incidence during storage.•Regardless of storage period, irradiated samples showed decreased microbial counts.•Overall irradiation treatment delayed color changes irrespective of dose.•Irradiated fruits exhibited improved sensory characteristics throughout storage. This study evaluated the effects of X-ray irradiation (0–1 kGy) on quality parameters of Korean strawberries during storage at 15 °C for 9 d. As compared to control, all irradiated samples exhibited dose-dependent decreases in microbial counts regardless of storage period. Irradiation significantly (p
