EFFECTS OF HEAT TREATMENTS ON THE DELAYED LIGHT EMMISSION AND ETHYLENE-FORMING-ENZYME SYSTEM IN PAPAYAS |

| Abstract:
The severity of heat damage to papayas was investigated. Hot air and hot water treatments were compared by determining the delayed light emission (DLE) and ethylene forming enzyme (EFE) of papayas. Heat inactivation kinetics showed greater retention of both DLE and EFE activities in hot air treated papayas compared to hot water treated papayas. Papayas heated in hot-air showed an atypical heat inactivation curve with a resurgence of EFE activity after 190 min at 48.5°C. | |
