利用魔芋葡甘聚糖复配膜、聚乙烯薄膜和无包装等处理，对“海顿1号”芒果进行采后常温（相对湿度为50％，温度为25℃）贮藏保鲜，并对货架期问芒果的硬度、病害、烂果率、失重率、可溶性固形物、呼吸强度、维生素C、可滴定酸和SOD，PPO，POD含量的变化进行了研究。结果表明：经魔芋葡甘聚糖复配膜和聚乙烯薄膜处理的芒果在第12天达到呼吸高峰，呼吸高峰与CK相比推迟了6d，且第9天时，SOD含量为CK的1．75倍。同时，魔芋葡甘聚糖复配膜和聚乙烯薄膜还能减少芒果病害、腐烂率与水分散失，保持较高的果实硬度和VC含量，降低果皮中PPO和POD活性，有效抑制芒果贮藏期间果皮褐变的发生，阻止可溶性糖积累和可滴定酸降解，延缓芒果的后熟进程。其中，魔芋葡甘聚糖复配膜比聚乙烯薄膜效果好，能更好地改善芒果在货架期的品质表现。

Fresh fruit of mango variety Haden 1 （Mangifera indicus L. ） were packaged with KGM compound film and polyethylene film with no film as the control, and stored at ambient temperature （ RH = 50%, T = 25 ℃）. The mangoes treated were determined during the shelf life in terms of hardness, disease incidence, bad fruit rate, weight loss rate, soluble solid content, respiration rate, Vitamin C content, titratable acid and SOD, PPO and POD activities. Results indicated that the KGM compound film and polyethylene film exhibited the highest respiration peak on the 12th day, 6 days late as against the control, and a higher SOD content at the day 9, 1.75 times higher than the control. The KGM compound film and polyethylene film also significantly reduced mango disease incidences, bad fruit rate and water loss rate, and had higher fruit hardness and Vitamin C content but lower PPO and POD activities in the peel, effectively restraining occurrence of peel browning during mango storage, accumulation of soluble sugar and degradation of titratable acid, and retarding mango ripening. KGM compound film gave a better effect than polyethylene film in improving the mango quality during the shelf life.
