Mango fruit has a limited shelf life and is susceptible to rapid quality deterioration owing to its climacteric nature. This study aimed to investigate the effects of a newly developed Aloe vera (AV)-based edible coating containing melatonin (ML) and salicylic acid (SA) on postharvest quality preservation of mango fruits during storage (15 days at 20 ± 2 °C).
The results showed that the treated fruits exhibited a noticeably preserved quality compared to the control fruits, with the highest marketability observed in AV + ML and AV + SA. Fruit firmness was better maintained in the treated fruits, particularly in the AV + ML treatment (4.5 kg/cm). Fruit treated with Al + SA exhibited lower respiration rate than control and other treatments. Treated fruits also showed lower weight loss and higher levels of total phenolic content, flavonoids, and antioxidant capacity compared to the control group. Color changes were also mitigated in treated fruits, with higher a* and lower b* values. The PCA analysis showed that the AV + ML treatment was very different from the other treatments and the control at 15 days of storage.
These findings highlight the effectiveness of AV + ML and AV + SA in preserving the postharvest quality of mango fruits, providing valuable insights into postharvest quality, and improving market acceptance.
芒果果实的货架期有限，由于其呼吸跃变特性，容易迅速变质。本研究旨在探讨一种新开发的含有褪黑素（ML）和水杨酸（SA）的芦荟（AV）基可食用涂层对芒果果实在储存期间（20±2°C下储存15天）采后品质保存的影响。
结果表明，与对照果实相比，处理后的果实品质明显得到保存，在AV+ML和AV+SA处理中观察到最高的适销性。处理后的果实能更好地保持果实硬度，尤其是在AV+ML处理中（4.5kg/cm）。用Al+SA处理的果实呼吸速率低于对照和其他处理。与对照组相比，处理后的果实还表现出较低的失重率和较高的总酚含量、类黄酮含量和抗氧化能力。处理后的果实颜色变化也得到缓解，a值较高，b值较低。主成分分析表明，在储存15天时，AV+ML处理与其他处理和对照有很大差异。
这些发现突出了AV+ML和AV+SA在保存芒果果实采后品质方面的有效性，为采后品质提供了有价值的见解，并提高了市场接受度。
