Effect of UV-C, Ultrasound and Modified Atmosphere Package Applications on Postharvest Quality of Starks Gold Sweet Cherry (Prunus avium L.) Cultivar

This study was carried out to determine the effects of UV-C, Ultrasound and modified atmosphere packaging (MAP) applications on postharvest quality of Starks Gold cherry (Prunus avium L.) variety. For this purpose UV-C (15 W, 10 min), ultrasound (35 kHz, 10 min, 20 °C) and MAP were applied to fruit. After the application, fruit was taken to the store (0 °C, 85-90% humidity) and quality changes on 4, 8, 12 and 16 days were examined. During the storage between 1.15% (4th days, MAP) and 10.54% (Day 16, Control) weight lossses 3.63% (4th day, MAP) and 3.98% (Day 16, Control) titratable acidity values 15.73% (Day 12, MAP) and 18.47% (4th day, MAP) soluble solid contents 14.81% (Day 4, Control) and 47.28% (16th day, MAP) postharvest losses had been determined. For color measurements during the trial, from 40.83 (day 4, MAP) to 57.37 (day 12 UV-C) L * values, 10.21 (day 12, UV-C) - 26.49 (Day 8, UV-C) a, 12.39 (Day 4, MAP) - 25.13 (Day 12, UV-C) b, 20.85 (day 4, UV-C) - 31.07 (day 8, UV-C) Chroma and between 31.18 (Day 8, UV-C) and 67.50 (Day 12, UV-C) hue values were determined. In this study it was seen that for the postharvest protection of the quality of Starks Gold, MAP, UV-C and Ultrasound applications were insufficient and MAP was more prominent if one of the applications was preferred. There was a need to elaborate on the subject with different studies
