TAILIEUCHUNG - Combined treatment of modified atmosphere packaging and 1-methylcyclopropene improves postharvest quality of Japanese plums

Two Japanese-type plum (Prunus salicina Lindell) cultivars, ‘Autumn Giant’ and ‘Black Beauty’, were harvested at commercial maturity stage and either packed in nonperforated modified atmosphere packaging (MAP). | Research Article Turk J Agric For 36 (2012) 563-575 © TÜBİTAK doi: Combined treatment of modified atmosphere packaging and 1-methylcyclopropene improves postharvest quality of Japanese plums Mustafa ERKAN*, Hakan ESKİ Department of Horticulture, Faculty of Agriculture, Akdeniz University, 07059 Antalya - TURKEY Received: ● Accepted: Abstract: Two Japanese-type plum (Prunus salicina Lindell) cultivars, ‘Autumn Giant’ and ‘Black Beauty’, were harvested at commercial maturity stage and either packed in nonperforated modified atmosphere packaging (MAP) or treated with a 500 ppb dose of 1-methylcyclopropene (1-MCP) alone or given a combination of 1-MCP and MAP. After these treatments, the plum samples were stored at 0 °C for 60 days. Treatment with either 1-MCP or modified atmosphere packaging (MAP) alone or with the 1-MCP+MAP combination reduced fruit softening, ethylene production, respiration rate, weight loss, and flesh browning, and resulted in higher flesh firmness, titratable acidity, and total soluble solids as compared to the control fruit at the end of the storage period. No decay was observed in either cultivar during the entire storage period. Furthermore, the combined treatment of MAP and 1-MCP had a clear advantage over the other treatments in reducing weight loss, retarding softening, increasing shelf life, and maintaining higher overall fruit quality for both cultivars of Japanese-type plums, especially after storage at 0 °C plus 7 days of storage at 20 °C. Key words: 1-MCP, ethylene, flesh browning, modified atmosphere packaging, Prunus salicina, storage Introduction The consumption of Japanese-type plums (Prunus salicina Lindell) has recently been increasing in Turkey due to high consumer demand. Japanese-type plums are generally consumed all over the world, but softening is a major obstacle for the marketing and eating quality of these plums. The marketing quality of plums can be maintained up to 2 .
