The objective of the present study was to evaluate the effectiveness of aqueous hexanal in prolonging the storage life of apple cv. ‘Royal Delicious’ while maintaining its quality. The influence of different concentrations of aqueous hexanal (1 mM, 2 mM and 3 mM) as a dip treatment for 2, 3 and 4 min was tested. Fruits given no hexanal treatment were taken as control. The treated and control apple fruits were stored under 1–2 °C and 80–90% RH for a period of 90 days and evaluated for physical and biochemical changes at regular interval of 15 days. The current study demonstrated that exogenous application of 1 mM hexanal applied as dip treatment for 3 min soaking time given to ‘Royal Delicious’ apple fruits retained higher firmness, reduced decay and improved the overall quality of the fruits upto 3-month storage under 1–2 °C. To conclude, postharvest application of aqueous hexanal as dip treatment holds promise in prolonging postharvest storage life and preserving quality of apple cv. ‘Royal Delicious’.

本研究的目的是评估含水己醛在延长苹果品种贮藏期限方面的有效性。'皇家美味'，同时保持其质量。测试了不同浓度的己醛水溶液（1 mM、2 mM 和 3 mM）作为浸渍处理 2、3 和 4 分钟的影响。未进行己醛处理的水果作为对照。处理过的和对照的苹果果实在 1-2°C 和 80-90% RH 下储存 90 天，并每隔 15 天定期评估物理和生化变化。目前的研究表明，外源性应用 1 mM 己醛作为浸渍处理，浸泡 3 分钟，使“皇家美味”苹果果实保持更高的硬度，减少腐烂并提高果实的整体质量，长达 3 个月的 1– 2℃。总结一下，含水己醛作为浸渍处理的收获后应用有望延长苹果品种的收获后储存期和保持品质。'皇家美味'。
