Effects of Special Package in Simulated Transportation of Flat Peaches

【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/cm²), but also reduce the weight loss rate (16.93%), respiratory intensity (72.08 mgCO²/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.
