Notes:
The effectiveness of radiation disinfestation of California peaches, nectarines and plums infested by Mediterranean fruit flies (Ceratitis capitata) and the effects of gamma-radiation up to 1 kGy (100 krad) on the sensory qualities of these fruits were studied. Medfly eggs in infested peaches and nectarines treated at 0.4–0.5 kGy (40–50 krad) in a Cobalt-60 irradiator did not hatch. Results in irradiated plums were inconclusive. Results of triangle tests with a taste panel of 15–20 show no differences in sensory qualities between plum and nectarine samples irradiated at 0.3 kGy and their controls. Some differences were detected between irradiated samples and controls: color and flavor of peaches at 0.3 kGy; color of plums and peaches 0.5 kGy; aroma of peaches and texture of plums at 0.5 kGy. At 1 kGy, differences were found in the texture of plums, nectarines, and peaches, and color and flavor of nectarines. Better control of harvesting, shipping and handling would help retain the qualities of these irradiated fruits.
