Postharvest handling techniques which have the potential for extending the market life of bananas and pawpaws by delaying ripening and avoiding undesirable physiological, biochemical and physical changes are examined, with reference to the marketing and export of these fruits from the ASEAN (Association of Southeast Asian Nations) region. Many different banana cultivars are grown in the region with resulting variations in fruit size and shape which hamper uniform production, handling, packing and marketing practices. Postharvest fruit ripening in bananas can be delayed by early harvesting and by controlling storage temperatures. The threshold temperature for the onset of chilling injury varies for different cultivars between 10 and 14 deg C. Modified atmosphere (MA) storage of fruits or holding fruits for a short period in 100% N2 following harvest can also delay ripening. The advantages and disadvantages of these and other techniques, including gamma irradiation, waxing and controlling ripening by ethylene application are discussed. Less information is available on handling techniques for pawpaws. Fruit ripening can be delayed by storing at a low temperature; however, chilling injury occurs in many cultivars after one week at 15 deg . Satisfactory colour and flavour develop in fruits ripened at 25 deg but not at 20 deg . MA storage extends storage life and ethylene application can accelerate ripening by 25-50%.
