Broccoli is rich in health-promoting compounds such as ascorbic acid and glucosinolates. However, amount of such compounds inevitably decrease along with the storage. This study was conducted to investigate the effects of 1-methylcyclopropene (1-MCP) and Modified Atmosphere Packaging (MAP) treatments alone or in combination on postharvest life and quality of broccoli heads during cold storage. MAP and 1-MCP+MAP significantly reduced weight loss, delayed surface color changes and chlorophyll breakdown, maintained visual quality, ascorbic acid, total phenol, soluble solid contents and titratable acidity compared with control as well as 1-MCP treatment. In 1-MCP plus MAP treated florets, approximate 47% and more chlorophyll and 24% more total phenol contents were found compared to control florets. 1-MCP plus MAP application better performed in maintaining the quality of broccoli florets during 28-day-storage. Overall results revealed that combined treatment can be recommended for commercial broccoli storage at 0 °C.

Kiwifruit is very perishable especially at 20 °C. The quality of kiwifruit with 1-MCP treatment stored at 20 °C in modified packages was investigated. Three different polyolefin films, including 0.03mm thickness polyethylene (PE), 0.03mm and 0.05mm thickness poly (vinyl chloride) (PVC) films, were used as packaging films. Kiwifruit were fumigated with 1-MCP to delay ripeness and then packaged with the three films and control (air). O2 and CO2 concentrations in the packages, flesh firmness, soluble solids concentration (SSC), titratable acidity (TA) and ascorbic acid were measured. MAP treatments could postpone the increase of TTS, inhibit the reduction of TA, and avoid the decrease of flesh firmness. Kiwifruit packaged in 0.05mm PVC obtained 33% TA more than control fruit and approximate 25 % retention of initial firmness. However, MAP didn’t maintain more ascorbic acid content of kiwifruit. In conclusion, MAP using polyolefin films combination 1-MCP treatment, especially 0.05mm PVC, might be more effective for preserving the quality of kiwifruit.

Fresh bell peppers were individually shrink-wrapped in film (SW), sealed in gas-flushed (5% O2, 10% CO2, 85% N2) film (GP) pouches, or stored unpackaged in cardboard packing crates (CN). All samples were stored at 13°C and changes in populations of total aerobic microorganisms, yeasts and molds, members of Enterobacteriaceae, and lactic acid bacteria were determined. In addition, overall sensory quality, color changes, and surface pH were monitored. SW peppers developed higher populations of total aerobic microorganisms, yeasts and molds, and Enterobacteriaceae than did CN peppers, but populations of other groups of microorganisms were similar. Color and surface pH of peppers did not differ in any of the treatments. SW and GP peppers remained unspoiled at least 6 weeks, whereas CN peppers spoiled in 3 weeks.

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

Cornelian cherries were stored in two types of polymeric films (low density polyethylene and polypropylene) and three gas combinations 5%O2 + 20%CO2 + 75%N2, 60%O2 + 20%CO2 + 20%N2 and Air) at 1 °C and 90-95% relative humidity for 35 days. Unpackaged cornelian cherries were used as a control. Samples were taken initially and at intervals of 7-days during storage, when quality parameters were measured. Results showed that modified atmosphere packaging (MAP) allowed the stored fruits to retain their weight and visual quality throughout the experiment, regardless of the gas combinations used, while by the end of the storage period the unpackaged fruit lost over 30% of their weight and consequently visual quality. Overall, packaging in 60%O2 + 20%CO2 polypropylene (PP) and air low density polyethylene (LDPE) could retard soluble solid contents, titratable acidity, ascorbic acid, anthocyanin index decrease and pH increase during the storage time. Additionally, such packaging could lead to better surface color preservation than that of fruits kept in open containers. Furthermore, packaging in air low density polyethylene and 60%O2 + 20%CO2 low density polyethylene could delay total phenolics accumulation and increase peroxidase activity to levels higher than those in the control. During the maintenance period, no symptoms of decay were observed.
