Breadfruit from Samoa potentially host the Pacific fruit fly (Bactrocera xanthodes) and so their export to New Zealand requires a disinfestation treatment. Heat treatments by air (HAT) or water (HWT) are common fruit-fly disinfestation treatments for tropical crops. Two breadfruit cultivars - Puou and Ma'afala - were subjected to three heat treatments, HAT-1 (minimum 47.2°C for 20 min at core), HAT-2 (49.0°C for 100 min at core) and HWT (47.2°C for 20 min at core), and an untreated control was also included. Fruit were stored for one week at 15°C followed by three days at 25°C. Disorders observed were heat damage to the skin (blackening) and increased decay on the body and stem-end. Heat damage was at an acceptably low level following HAT-1 but was unacceptable following HAT-2 or HWT. Initial results suggest that a HAT can be tolerated, but the effect of ramp rate and the potential of using a two-step HWT system should be examined. [ABSTRACT FROM AUTHOR] |
