Postharvest Disease Development in the Mango Supply Chain in Thailand

The aim of this research was to study of the development postharvest diseases during the supply chain of exporting mango. This experiment was assorted by sampling fruit randomly from the processes during mango handling in a packing house. The mango production comprised 5 processes, which were step 1 - no treatment (mangoes were kept from the field and then transport to the exporter), step 2 - pedicle cutting to 1 cm left and then dipped with 200 ppm chlorine, step 3 dipping into hot water at 50 degrees C for 3 min, step 4 - dipping with tap water for a few minutes and then dipping into 400 ppm ethephon, and step 5 - incubation in hot vapor at 47 degrees C for 20 min. The results show that steps 3-5 comprised lower infected areas and disease incidences than step 1 and 2. Therefore, step 3 was the most important step for decreasing mango postharvest diseases in the postharvest handling of exporting mango.
