In this study, the aim is to determine the storage condition of Ziraat 900 sweet cherry cultivar in province of Mersin in Turkey and to find out the effectiveness of treating the UV-C, Hot Water and the combination of both in protecting the fruit quality during storage in MAP (modified atmosphere packaging). For this aim, clusters of control group were not subjected to any application in the postharvest period, while clusters of treatment group were performed with VilberLourmat UV-C lamp glimmered 254 nm wavelength from 100 (0.25 kJ / m 2) cm distance for 4 minutes in the sterile cabinet without any fumigation. Hot water application was also performed by maintaining of clusters in the water bath at 50 °C for 1 minutes. After treatment, by covering of all clusters (in the control and treatment groups) with stretch film with packing containers called modified atmosphere packaging, all clusters were stored at 0 ± 1 °C and 90 ± 5% relative humidity conditions in the cold storage room. For this purpose, cherry fruits was kept for 20 days in 0°C cold storage. Weight loss and color (L*, a*, b*, Chroma, and Hue), SSC (soluble solid content), titratable acidity, pH, total phenolics and total antioxidant changes that occurred postharvest storage were examined. As a result of this study, an increase in weight loss was detected during storage in all applications. As a result of study, it was concluded that cluster of Ziraat 900 sweet cherry cultivars subjected to hot water and UV-C can be stored for optimal 20 days by covering with stretch film.
