Conteúdo: 	`Solo' papaya (Carica papaya L.) fruit removed at different points  from a commercial packing house shoved that skin injury due to mechanical damange increased as fruit moved through the handing system. The ocurrence of "green islands"--areas of skin that remain green and sunken when the fruit was ripe-- apparently were induced by mechanical injury. Skin injury was seen in fruit samples in contact with the sides of field bins, but not in fruit taken from the center of the bins. Bruise-free fruit at different stanges of ripeness (5% to 50% yellow) were dropped from heights of 0 to 100 cm onto a smooth steel plant to simulate drops and injury incurred during commercial handing. No skin injury ocurred, although riper fruit showed internal injury when dropped fromhigher than 76 cm. Fruit (10% to 15% yellow) dropped onto sandpaper from a height of 10 cm had skin injury symptoms similar to those seen on fruit from the comercial handling system. These results suggest that abrasion and puncture injury were more important injury for papaya fruit. Heating fruit at 48C for approximately 6 hours or unitil fruit core temperature (FCT) reached 48.5C aggravated the severity of skin injury. Delays in the application of heat treatment from dropping did not reduce the severity of skin injury significantly, except for fruitheated 24 hours after droping. Waxing fruit alleviated the severity of skin injury, whether applied before or after the heat treatment.
