摘　　要：【目的】筛选出保持蟠桃运输后常温货架期最佳品质的包装方式,研究蟠桃在物流运输后不同包装对蟠桃货架期硬度、可溶性固形物(SSC)、腐烂率、相对电导率、多酚氧化酶(PPO)、过氧化物酶(POD)、VC含量的影响。【方法】以英格尔蟠桃为试材,采用不同保鲜处理(无包装,无包装+保鲜袋(0.02mm),自制缓冲垫,自制缓冲垫+保鲜袋(0.02mm),发泡网,发泡网+保鲜袋(0.02mm)),共6个处理,物流运输后蟠桃常温货架期连续测定4 d的理化指标。【结果】相较于其他处理,自制缓冲垫+保鲜袋处理保鲜效果最佳,自制缓冲垫次之,均可有效维持蟠桃较高的SSC、硬度、POD、VC的含量,有效抑制果实腐烂率、相对电导率、PPO的上升。【结论】保鲜袋处理效果优于无保鲜袋处理,自制缓冲垫、发泡网处理保鲜效果优于无包装处理;自制缓冲垫、自制缓冲垫+保鲜袋处理可保持较好的物流运输后果实货架期品质,降低运输途中由于机械碰撞造成的果实货架期品质下降的问题,实现蟠桃远距离运输。【Objective】Select the best packaging method to maintain the best shelf-life quality of flat peach after transportation,the effects of different packaging on shelf-life firmness,soluble solid(SSC),decay rate,relative conductivity,polyphenol oxidase(PPO),peroxidase(POD)and vitamin C(VC)were studied.【Methods】Using Ingle flat peach as test material,the physical and chemical indexes of flat peach with shelf life of 4 days at room temperature were determined after logistics transportation in different fresh-keeping packages(no packaging,no packaging+storage bag,homemade buffer pad,homemade buffer pad+storage bag,foaming net,foaming net+storage bag).【Results】Compared with other packaging home-made cushion+plastic bag,the fresh-keeping effect was the best,followed by homemade buffer pad,which could effectively maintain the higher SSC,hardness,POD and VC contents of the peach,and effectively inhibit the rise of fruit decay rate,relative electrical conductivity and PPO.【Conclusion】The effect of plastic bag packaging is better than that of non-plastic bag packaging,the effect of homemade buffer pad and foaming net packaging is better than that of non-packaging group,homemade buffer pad,homemade buffer pad+plastic bag packaging can maintain better quality of fruit shelf life after logistics transportation,reduce the problem of fruit shelf life quality decline caused by mechanical collision during transportation,thus achieving the purpose of long distance transportation of peaches.
