Abstract:

Objective: This study aims to investigate the effects of different anti-vibration packaging materials on the shelf-life quality of kiwifruit during the storage and transportation of ‘Xu Xiang’ kiwifruit, as well as the effects of expanded polyethylene (EPE) packaging treatment on the activity of relevant enzymes and gene expression during the malic acid metabolism of kiwifruit after harvest. Method: Three kinds of anti-vibration packaging treatments, namely, foam mesh bag packaging, expanded polystyrene (EPS) and expanded polyethylene (EPE), were adopted, and road transportation was simulated in a 72 h vibration experiment on a vibration test bench. The shelf-life qualities of kiwifruit (hardness, color, and the contents of titratable acid, soluble solids, vitamin C and total phenol) were determined. Then, the indicators of cell membrane damage (malondialdehyde, relative conductivity and lipoxygenase activity) were analyzed, and the activity and gene expression of enzymes involved in malic acid metabolism were measured and the correlation among the measured data was investigated. Result: Compared with the foam mesh bag and EPS packaging, the EPE packaging maintained the hardness and color of kiwifruit fruits, promoted the synthesis of saccharides, and inhibited the decomposition of antioxidants. It also slowed down the rise of relative conductivity and malondialdehyde content, reduced lipid peroxidation and maintained the integrity of cell membranes. Furthermore, results showed that malic acid content was positively correlated with synthesis-related NAD-MDH and PEPC enzyme activities, and negatively correlated with degradation-related NADP-ME enzyme activities. EPE packaging stabilized the malic acid metabolism-related enzyme activities and gene expression. Conclusion: EPE anti-vibration packaging treatment is beneficial to the maintenance of shelf-life quality of kiwifruit fruit during storage and transportation. It exhibits a positive effect on malic acid metabolism of kiwifruit fruits.
