Abstract

Introduction – ‘Namwa’ is one of Thai native banana cultivars. It showed a rapid ripening which leads to senescence-associated peel blackening during the postharvest period. Thus, the effect of electrostatic atomized water particles (EAWPs) on the postharvest quality and senescence of ‘Namwa’ banana was assessed. Materials and methods – Fruit samples were pretreated with EAWPs for 0 (control), 0.5, 1.0, 1.5 and 3 h. After the treatment, the fruits were kept in polypropylene bags with two 5-mm holes and stored at ambient temperature (25±2 °C) under dark conditions. Results and discussion – The 1-h EAWPs treatment performed best at delaying ripening, reducing weight loss, and retarding peel color change, especially the Hue angle and L* value, in ‘Namwa’ banana during storage. It also efficiently delayed the reduction of Chlorophyll a and b contents. Interestingly, EAWPs treated samples showed higher hydrogen peroxide (H2O2) content in peel tissues just after treatment and decreased afterward to a level lower than the control. Moreover, treatment with EAWPs resulted in higher total phenolic content in peel tissues and lower polyphenol oxidase (PPO) and peroxidase (POD) activities associated with lesser peel blackening. Conclusion – The EAWPs treatment maintained postharvest quality of ‘Namwa’ banana through delayed ripening and senescence-associated peel blackening. © 2021 International Society for Horticultural Science.
