摘　　要：目的:研究4种包装材料对西番莲果实的保鲜效果。方法:以“黄金”西番莲(八成熟)为研究材料,果实采后分别用聚氯乙烯(PVC)保鲜膜、聚乙烯(PE)保鲜袋、双向拉伸聚烯烃(BSP)热收缩膜和可降解气调(BMA)保鲜袋进行包装,以未包装的果实为对照,于(25±1)℃、相对湿度80%下贮藏15 d,每3 d测定果实外观品质、果肉营养品质和果实耐贮性等指标。结果:与对照组相比,4种包装材料处理均能延缓果实呼吸和乙烯高峰的出现,减缓果皮丙二醛含量上升而稳定细胞膜结构,延缓果实转黄和皱缩,保持果实较低失重率和较高商品率;维持果皮外观色泽和果肉营养物质含量。其中以BSP热收缩膜包装处理效果最佳。结论:BSP热收缩膜包装处理可作为一种提高“黄金”西番莲果实采后品质、延长其保鲜期的适宜保鲜技术。Objective:The preservation effects of four packaging materials on passion fruit were studied.Methods:The fruit of passion flower cv.Huangjin(maturity:eight)was used as the research material,and passion flower fruit was treated via polyvinyl chloride(PVC)film,polyethylene(PE)bag,bidirectional stretch polyolefin(BSP)heat shrinkable film,biodegradable modified atmosphere(BMA)bag,respectively,with untreated ones as the control group.Then,the fruits was stored at temperature of(25±1)℃and relative humidity of 85%for fifteen days,and the preservation indices of fruit were measured every three days.Results:Compared to control passion fruit,the four treatments of packaging materials could delay the peak of respiration and ethylene,slow down the increase of pericarp malondialdehyde content to stabilize cell membrane structure,delay the fruit etiolation and shrinkage,keep a lower weight loss rate and a higher commercially acceptable fruit rate,and maintain the pericarp appearance color and pulp nutrients contents.Among the different packaging materials,BSP heat shrinkable film had the best effects.Conclusion:The BSP heat shrinkable film might be used as a suitable storage technology to improve the quality and prolong the storage life of harvested"Huangjin"passion fruit.
