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.
