电商包装方式对水蜜桃运输缓冲防震及货架品质的影响

目的 研究常规电商包装中不同缓冲材料和包装量对水蜜桃在跌落、随机振动条件下的损伤防护及货架品质的影响。方法 以“华玉”水蜜桃为试材,分别采用瓦楞纸隔板+单盒包装、聚乙烯发泡棉(EPE)内衬+单盒包装、瓦楞纸隔板+两盒包装及EPE内衬+两盒包装等4种形式包装后,依据ISTA 3A标准开展模拟公路运输实验,分析水蜜桃货架期品质变化。结果 瓦楞纸隔板+两盒包装在面跌落时的加速度仅为90.306 m/s²,缓冲性能比单盒包装更好,但其在随机振动中响应较大,而EPE内衬+单盒包装处理受随机振动影响最小,一阶共振响应和二阶共振响应分别为0.012 2 g²/Hz和0.014 3 g²/Hz。模拟运输后在常温货架条件下,瓦楞纸隔板+两盒包装的水蜜桃在货架期内始终保持较低的呼吸强度和乙烯释放量,维持较好的外观品质。相较于单盒包装,两盒包装对维持水蜜桃质地、可溶性固形物、总酸含量及外观品质具有积极作用。结论 综合来看,以瓦楞纸隔板为缓冲材料,两盒包装更有利于水蜜桃电商物流运输中的震动防护,并能较好地保持货架品质,为适宜水蜜桃的电商物流包装...

Effects of E-commerce Packaging on Transportation Cushioning and Shelf Quality of Honey Peach

The work aims to study the effects of different cushioning materials and packaging quantity on the damage protection and shelf quality of honey peach under the conditions of drop and random vibration in conventional E-commerce packaging. With "Huayu" honey peach as the test material, four forms of packaging were adopted:corrugated board partition + single box, expandable polyethylene (EPE) lining + single box, corrugated board partition + two boxes and EPE lining + two boxes. Then, the road transportation experiment was simulated according to ISTA 3A standard to analyze the changes of honey peach shelf quality. The acceleration of corrugated board partition + two boxes packaging when falling on the surface was only 90.306 m/s2, and the cushioning performance was better than that of single box packaging, but its response was larger in random vibration, while EPE lining + single box packaging was least affected by random vibration, and the first-order and second-order resonance responses were 0.012 2 g2.Hz-1 and 0.014 3 g2.Hz-1 respectively. After simulated transportation, under the normal temperature shelf condition, the honey peach packed in corrugated board partition + two boxes always maintained low respiratory intensity and ethylene release during the shelf life, and had better appearance quality. Compared with single box packaging, two boxes packaging played a positive role in maintaining the texture, SSC, TA content and appearance quality of honey peach. Overall, with corrugated board partition as cushioning material, the packaging of two boxes is conducive to the vibration protection of honey peach in logistics transportation, and can better maintain the shelf quality, which is a suitable packaging method for E-commerce logistics of honey peach.
