Outline
To investigate the effects of preharvest 1-methylcyclopropene (1-MCP) treatment and post-harvest Ag/ZSM-5 zeolite nano-preservation paper on the maturation process and storage quality of Myrica rubra cv. Dongkui.
The effects of preharvest 1-MCP spraying on fruit maturity was evaluated based on in-tree parameters including appearance, fruit diameter, soluble solids content, titratable acidity, color indices and so on. Concurrently, the synergistic effects of post-harvest Ag/ZSM-5 zeolite nano-preservation technology were analyzed under both ambient and low-temperature storage conditions, with assessments of weight loss, sugar-acid profile, texture, color, polyphenol oxidase (PPO) and peroxidase (POD) enzyme activities.
Preharvest 1-MCP treatment effectively delayed the in-tree maturation process, postponing color initiation by 4 days and suppressing fruit expansion. It also reduced post-harvest weight loss during low-temperature storage, maintained sugar-acid ratio balance and color stability, and enhanced POD enzyme activity, thereby delaying fruit senescence. Meanwhile, standalone post-harvest Ag/ZSM-5 zeolite nano-preservation paper reduced weight loss under ambient storage, maintained fruit firmness and cohesiveness, preserved red hue (a), and alleviated cell membrane damage. Furthermore, the combined pre- and post-harvest treatments drastically reduced PPO enzyme activity by 86.31% and mitigated membrane lipid peroxidation during low-temperature storage.
Preharvest 1-MCP application delays bayberry maturation, while its integration with post-harvest Ag/ZSM-5 zeolite nano-preservation paper significantly enhances storage tolerance and extends shelf life under room and low temperature by preserving fruit quality and elevating antioxidant activity during storage.
