【摘要】 【目的】研制一种具有减振功能的蟠桃专用包装盒及其套件，分析其在运输中的使用效果。【方法】以新疆蟠桃为试材，采用模拟运输振动方式，测定果实的损伤指数、失重率、硬度、呼吸速率、可溶性固形物(TSS)含量、过氧化氢酶(CAT)活性等指标，分析蟠桃专用包装盒防止蟠桃振动和跌落损伤的效果。【结果】相比于对照和普通包装盒，专用包装盒不仅可以有效减少蟠桃果实表面损伤率(10.53%)、维持果实硬度(5.0 kg/cm~2),还可以降低失重率(16.93%)、呼吸强度(72.08 mgCO~2/kg·h)和乙烯释放速率速率(2.7μl/kg·h),减少丙二醛(MDA)的积累(1.21 mmol/g),抑制多酚氧化酶(PPO)活性(11.78 U/g),增强过氧化氢酶(CAT)活性(25.73 U/g),延缓果实的衰老。【结论】蟠桃专用包装盒具有显著减少果实损伤和延缓衰老的效果，更利于蟠桃运输后贮藏品质的保持。更多还原

【Abstract】 【Objective】 To develop a special packaging box and a kit for flat peaches with damping function and to explore its effect in transportation.【Methods】 Xinjiang flat peach as the test material, the simulated transportation vibration method was applied and the damage index, weight loss rate, hardness, respiration rate, soluble solids(TSS) content, catalase(CAT) activity and other indicators of the fruit were measured to analyze whether the special packaging box for flat peaches prevented vibration and fall damage of flat peaches.【Results】 Compared with the control and ordinary packing box, the special packing box can not only effectively reduce the surface damage rate of flat peach fruit(10.53%), maintain the fruit hardness(5.0 kg/cm~2), but also reduce the weight loss rate(16.93%), respiratory intensity(72.08 mgCO~2/kg·h) and ethylene release rate(2.7 μL/kg·h), reduce the accumulation of malondialdehyde(1.21 mmol/g), inhibit the activity of polyphenol oxidase(11.78 U/g), enhance the activity of catalase(25.73 U/g), and delay the senescence of fruits.【Conclusion】 The special packaging box for flat peaches has the effect of significantly reducing fruit damage and delaying its senescence, which is more conducive to maintaining the storage quality of flat peaches after transportation.更多还原
