“…Additionally, kiwifruit and mushrooms treated with HRW showed higher free radical scavenging activity and lower rot rate as compared to the non-treated groups ( Chen et al., 2017 ; Hu et al., 2018 ). In our previous study, we observed that hydrogen-rich water treatment delayed the softening process and prolonged the storage time by modifying the cell wall metabolism and cell wall composition in postharvest okras ( Dong et al., 2023 ). Similarly, here we demonstrated again that HRW treatment could prolong the shelf life of postharvest okras.…”

Hydrogen-rich water (HRW) treatment has been reported to delay the softening and senescence of postharvest okras, but its regulatory mechanism remains unclear. In this paper, we investigated the effects of HRW treatment on the metabolism of several phytohormones in postharvest okras, which act as regulatory molecules in fruit ripening and senescence processes. The results showed that HRW treatment delayed okra senescence and maintained fruit quality during storage. The treatment upregulated all of the melatonin biosynthetic genes such as AeTDC, AeSNAT, AeCOMT and AeT5H, contributing to the higher melatonin content in the treated okras. Meanwhile, increased transcripts of anabolic genes but lower expression of catabolic genes involved in indoleacetic acid (IAA) and gibberellin (GA) metabolism were observed in okras when treated with HRW, which was related to the enhanced levels of IAA and GA. However, the treated okras experienced lower abscisic acid (ABA) content as compared to the non-treated fruit due to the down-regulation of its biosynthetic genes and up-regulation of the degradative gene AeCYP707A. Additionally, there was no difference in γ-aminobutyric acid between the non-treated and HRW-treated okras. Collectively, our results indicated that HRW treatment increased levels of melatonin, GA and IAA, but decreased ABA content, which ultimately delayed fruit senescence and prolonged shelf life in postharvest okras.

During postharvest storage, the metabolism of cell wall components greatly affects the quality of fruits and vegetables. Utilizing 1‐methylcyclopropene (1‐MCP) as an ethylene receptor inhibitor and modified atmosphere (MA) separately or in combination (1‐MCP+MA) were investigated for their impact on Zizania latifolia quality during postharvest storage. The treatments effectively controlled firmness increase, color degradation, and reductions in soluble protein, reducing sugar, total phenol, and ascorbic acid content, with the combined 1‐MCP+MA showing the most significant effect. These treatments also moderately changed soluble pectin, protopectin, cellulose, and hemicellulose content, preserving the activities of essential enzymes and the expression of enzyme genes. The combined treatment particularly demonstrated superior preservation capabilities, holding promise for reducing postharvest losses and maintain the storage quality of edible produce, offering insights for efficient postharvest storage and freshness maintenance of fruits and vegetables.

Postharvest handling is an important approach to reduce loss and ensure the global supply of fresh fruits and vegetables (FVs). Recently, nanomaterials are increasingly recognized for their great potentials in extending shelf life and maintaining the quality of postharvest FVs owing to their unique properties and outstanding functions with extremely small sizes. This study reviews critically applications of nanotechnology in shelf life extension and quality maintenance of postharvest FVs via nano-packaging, nano-coatings, and micro/nano-bubbles. The advantages of these nanotechnologies to effectively compensate for the shortcomings of the traditional methods are highlighted alongside future research directions at a large low-cost scale. Generally, nano-packaging, nano-coatings, and micro/nano-bubbles have the functions to modify gas or solvent permeability, inhibit pathogens infection, enhance antimicrobial capacity, and regulate the physiological activity of postharvest FVs. With the development of nanotechnology and quality control measures, it can be expected that green nanopreservation technology will be an important and novel alternative for the storage and transportation of postharvest FVs.
