Effect of different storage conditions and combined use of ethylene blocker on ‘Shalimar’ apple quality

Abstract Post-storage apple quality is affected by various factors, for instance, the stage of maturity at harvest, storage conditions, and post-harvest treatments. Storage conditions are crucial in deciding the fruit quality and flavor perceived by consumers. The variety 'Shalimar' (Topaz x Golden Delicious) is known to be resistant to scabs and mildew. To date, no research articles have established the optimal storage method for this particular cultivar. This study investigated the fruit quality and volatile profile of the 'Shalimar' apple variety as affected by storage conditions i.e., controlled atmosphere (CA), dynamic control atmosphere (DCA), and 1-methylcyclopropene (1-MCP) application after 7 months of storage. It was found that CA and DCA were both effective techniques to maintain fruit quality. 1-MCP significantly improved firmness maintenance in all storage treatments. CA-stored and 1-MCP-treated fruit showed a reduction in volatile organic compounds. DCA with carbon dioxide monitoring (DCA-CD) was an effective technique in maintaining 'Shalimar' fruit quality and ensuring higher volatile compound production after 7 months of storage.
