摘要:

目的: 探究‘徐香’猕猴桃贮运过程中不同减振包装材料的减损防伤效果和对猕猴桃货架期品质的影响,以及发泡聚乙烯包装对猕猴桃采后苹果酸代谢过程中相关酶活性以及基因表达的作用,以期为物流过程猕猴桃风味品质保持提供理论依据。方法: 采取泡沫网袋、发泡聚苯乙烯(EPS)、发泡聚乙烯(EPE)3种减振材料包装猕猴桃,通过在振动实验台72 h振动实验模拟道路运输,测定果实贮藏过程货架期品质(硬度、色泽、可滴定酸、可溶固形物、维生素C和总酚含量)变化;对细胞膜损伤指标(丙二醛、相对电导率和脂氧合酶活性)进行分析;测定猕猴桃果肉苹果酸代谢相关酶和基因表达量变化。结果: 与泡沫网袋和EPS包装相比,EPE包装能够维持猕猴桃果实硬度和色泽,延缓抗氧化物质含量下降,抑制膜脂过氧化程度并维持细胞膜完整性。猕猴桃果实贮藏过程的苹果酸含量与NAD-MDH、PEPC酶活呈正相关,与NADP-ME酶活呈负相关,EPE包装能够保持苹果酸代谢相关酶NAD-MDH、PEPC的酶活性和基因表达水平。结论: 在猕猴桃鲜果贮运过程中EPE减振包装有利于贮运过程其货架期品质的保持,对猕猴桃果实苹果酸的代谢具有积极作用。

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.
