不同包装对猕猴桃经运输跌落后货架品质的影响

Impact of Diverse Packaging on Shelf Quality of Kiwifruit after Falling during Transportation

  • 摘要: 为探究不同包装方式对经历跌落冲击的‘徐香’猕猴桃货架(20℃)品质的影响,分别选用4种方式(泡沫蛋托组:纸箱+聚苯乙烯(EPS)泡沫分果包装箱;分果纸盒组:珍珠棉网套+双层瓦楞纸分果包装盒;泡沫箱组:纸箱+EPS泡沫箱;纸箱组:珍珠棉网套+纸箱)包装猕猴桃,并进行物流跌落冲击模拟试验,以未进行跌落试验且用打孔聚乙烯(PE)保鲜自封袋包装的猕猴桃为对照组,测定果实货架期间的腐烂率、硬度、色泽、呼吸强度、失重率、相对电导率、可溶性固形物含量(SSC)、可滴定酸(TA)含量和VC含量。结果表明,泡沫蛋托组的猕猴桃果实在经跌落后,其货架期间的腐烂率、硬度、色泽、呼吸强度、失重率、细胞膜渗透率、可溶性固形物含量、可滴定酸含量等指标优于其他包装处理组,与未经跌落的对照组果实品质最为接近,而分果纸盒组的果实货架品质最差。综上,泡沫蛋托组的分果托盘减振包装方式可有效降低猕猴桃果实受到的跌落冲击力,避免了果实因受到跌落损伤而引起的品质加速劣变。

     

    Abstract: In order to explore the effect of different packaging methods on the shelf quality(20 ℃) of ‘Xuxiang’ kiwi fruits after the falling impact, the kiwifruits were packaged with four ways(foam egg tray group: corrugated paper(CP) boxes + EPS foam fruit separation box; fruit separation carton group: pearl cotton net cover + double CP fruit separation box; foam box group: CP boxes + EPS foam box; carton group: pearl cotton net cover + CP boxes). A logistics drop impact simulation test was conducted. The kiwifruits packaged in perforated PE bags without falling were used as the control group. The decay rate, hardness, color, respiratory strength, weight loss rate, relative conductivity, soluble solid content(SSC), titratable acid(TA) content, and VC content of fruits were determined during the shelf life. The results showed that the indexes of decay index, firmness, color, respiration intensity,weight loss, cell membrane permeation rate, soluble solid content, and titrable acid content of kiwifruits in foam egg tray group after drop impact test were better than those in other packaging groups, and the fruit quality was closest to that of the control group. While the shelf quality of kiwifruit in carton group was the worst. Which suggested that the separate fruit tray vibration reduction packaging method in foam egg tray group can effectively reduce the falling impact force of kiwifruit and avoid the accelerated quality deterioration of kiwifruit due to drop damage.
