title: Shelf-life extension of highbush blueberry using 1-methylcyclopropene stored under air and controlled atmosphere.
abstract: The potential of 1-methylcyclopropene for controlling ripening in 'Lateblue' blueberry fruit was explored. After harvest, blueberry fruits were exposed to 1-MCP (0.3 and 0.6μll(-1)). After treatment, samples were stored in air at 0°C for 35days and in a controlled atmosphere (3kPa O2+11kPa CO2) for 60days. Quality parameters were monitored (weight loss, total soluble solids content, titratable acidity, firmness, anthocyanin content, phenolic content, total antioxidant capacity). Blueberries treated with 1-MCP showed a reduced weight loss during storage and a lower total soluble solid content compared to untreated fruit. High titratable acidity values were observed after controlled atmosphere storage, but no significant effect of 1-MCP on this parameter was observed. 1-MCP had no significant effects on anthocyanins, phenolics or antioxidant activities.
