ABSTRACT :

The Commission on Postharvest Handling of Horticultural Produce of the International Society for Horticultural Science seeks to disseminate the most important research findings and technological innovations presented during the many symposia held in this field around the world. Promising new postharvest studies in the fields of non-destructive measurement of quality, consumer quality preferences, the biochemical basis of ethylene production, fermentation and aroma ester biosynthesis, and disease resistance are reported, as is information about gene-manipulated cultivars with an extended shelf life. Cultivation and climate have specific effects on postharvest quality and delays in harvesting date must be avoided. Yeasts, bacteria, fungistatic plant extracts and heat treatments are being investigated for control of postharvest decay. More sophisticated refrigeration techniques with a higher RH, controlled atmosphere storage, ethylene absorption and nitrogen flushing can be used to further extend s

torage life. Also, new modified atmosphere atmosphere packaging (MAP)-films with micropores or absorbent layers for ethylene and water vapour are available. Management with intelligent dynamic control systems will be useful during refrigerated storage. For precooling using forced-air cooling, an ice bank is recommended as a cold source. Temperature management during and after packing requires greater attention. To reduce bruising during transport, less advanced fruit maturity, a minimum vibration level (< 0.75 g) and a convenient packaging (norms for compression pressure) are important.
