The effect of cold disinfestation treatment on the quality of Washington Navel oranges in Sunraysia.

ABSTRACT :

 

Trials over 2 years were undertaken to determine the effect of cold disinfestation at 1 deg C on the internal and external quality of Washington Navel oranges. Chilling injury in the form of cold scald and rind pitting were significantly increased by cold disinfestation. The incidence and severity of chilling injury was low (maximum 7% of fruits rejected due to chilling injury), indicating that 16 days of storage at 1 deg will result in minimal fruit loss due to chilling injury. Extended storage at 10 deg after cold disinfestation at 1 deg for 16 days increased the severity of the chilling injury symptoms observed. The incidence of postharvest fungal breakdown was high in the second year of the trial and red Alternaria spot was high in the first year. Oleocellosis was present in almost all fruits tested and severe in 75% of the fruit. The overall external quality of the fruits was highly influenced by grower but no correlation between fruit quality and specific management practices could be made

. These results indicate that 'in transit' cold disinfestation would be a feasible treatment for export Washington Navel oranges but with the provisos that total transit time is kept to a minimum and that care is taken to minimize postharvest fungal breakdown and incidence of oleocellosis.
