Effect of Modified Atmosphere Packaging (MAP) and UV-C Irradiation on Postharvest Quality of Red Raspberries

Red raspberries (Rubus idaeus L.) are highly appreciated by consumers. However, their postharvest shelf life scarcely exceeds 5 d under the refrigeration temperatures usually applied during commercialization, due to high susceptibility dehydration, softening and rot incidence. Thus, objective of this study was investigate ability UV-C radiation (UV1: 2 kJ m?2 UV2: 4 m?2), passive modified atmosphere packaging (MAP) with transmission rates (TR) for O2 CO2 1805 mL d?1 1570 (MAP1), 902 785 (MAP2), respectively, combination both technologies prolong raspberries’ at 6 °C. Their influence on respiration, physicochemical parameters, microbiological nutritional quality assessed 12 storage. The a film d?1, produced synergistic effect against development, delaying senescence fruit. UV2MAP2 MAP2 samples only showed 1.66% incidence after 8 also had higher bioactive content (1.76 g kg?1 gallic acid equivalents (GAE), 1.08 catechin (CE) 0.32 cyanidin 3-O-glucoside (CGE)) than control end life. Moreover, mass loss minimal (0.56%), fruit color firmness were maintained rest batches not suitable commercialization excessive mold development.
