Abstract
This study evaluated the effects of delayed storage followed by storage under static controlled atmosphere (CA) and dynamic controlled atmosphere established by respiratory quotient (DCA-RQ) with and without 1-methylcyclopropene (1-MCP) application on quality and volatile profile of “Cripps Pink” apple. A fruit batch was immediately stored at 1.5 ± 0.1°C, and another remained for 7 days at 20°C (delay) until storage. The storage conditions were: (1) CA (1.0 kPa O2 + 1.0 kPa CO2); (2) DCA-RQ 1.3; (3) DCA-RQ 1.5. Additionally, for each storage condition and delay strategy, a batch of fruit was treated with 1-MCP, and another batch was left untreated. Practical applications DCA-RQ 1.3 maintened flesh firmness even without 1-MCP and with delayed storage. 1-MCP application reduced all esters. Delayed storage increased the esters concentration and when associated with DCA-RQ 1.3 and 1.5 should be recommended to reduce decay, increase the healthy fruit amount, and improve the aroma emission of “Cripps Pink” apple.
