Non-chemical disinfestation: a freezing approach.

The effect of a short freezing period on fruit quality was evaluated as part of an assessment of the potential for using freezing temperatures to shorten the cold storage period required to achieve effective insect disinfestation of fruits using combinations of controlled atmosphere storage and cold storage. Packham's pears and Pink Lady apples were subjected to freezing temperatures (-5 deg C) for 2, 4 or 6 days (pears) and 1, 2 or 3 days (apples). The fruits were then stored in 1-2 kPa O2 at -1 deg C for 2, 4 or 6 weeks. Finally, the fruits were stored in air for 3 weeks at +1 deg C to simulate conditions during sea freight. Fruits were then evaluated for quality (taste, firmness, colour, internal browning and skin injury). No significant difference was found in consumer acceptance of treated apples and pears (pears frozen for 6 days were not tested). However, more than one day at -5 deg C produced unacceptable levels of visual damage (mainly internal and external browning) in both apples and

pears.
