The combined effect of aqueous chlorine dioxide (ClO2) or fumaric acid with ultraviolet-C (UV-C) on postharvest quality of “Maehyang” strawberries was examined. The strawberries were treated with distilled water, 50 mg L−1ClO2, 0.5% fumaric acid, 5 kJ m−2UV-C irradiation, and a combination of 50 mg L−1ClO2/5 kJ m−2UV-C and 0.5% fumaric acid/5 kJ m−2UV-C. The combined treatment of fumaric acid/UV-C reduced the initial populations of total aerobic bacteria and yeast and molds in the strawberries by 2.25 and 2.01 log CFU g−1, respectively. Sensory evaluation results indicated that the combined treatment provided better sensory scores than did the control. These results suggest that postharvest treatments of either ClO2 or fumaric acid with UV-C can be useful for maintaining the quality of ‘Maehyang’ strawberries.
