Impact of dynamic controlled atmosphere storage and 1-methylcyclopropene treatment on quality and volatile organic compounds profile of ‘Galaxy’ apple

Thus, the aim of this work was to evaluate the effect of between 1-MCP with DCA-RQ, DCA based on chlorophyll fluorescence (DCA-CF), controlled atmosphere (CA) and ultralow oxygen (ULO) on the physical and chemical quality and VOCs of ‘Galaxy’ apples after 8 months of storage plus 7 d of shelf life. All storage conditions were performed with or without 0.625 μL L−1 of 1-MCP application. Despite of 1-MCP maintaining some quality attributes, the production of VOCs was reduced even under apples stored under DCA-RQ1.5 with it. DCA-RQ1.5 without 1-MCP maintained better VOCs than CA, ULO, DCA-RQ1.3 and DCA-CF. DCA-RQ1.5 without 1-MCP showed a similar flesh firmness compared to DCA-RQ1.5 with 1-MCP application, with high VOCs emission and flesh firmness. 1-MCP, despite of maintaining flesh firmness, has no positive effect in other attributes in apple under DCA-RQ1.3. Moreover, this regulator reduced the production of VOCs in all storage conditions.Graphical abstract
