Abstract
Prestorage heat treatments at 47-53 degrees C for 1-3 min were investi gated as a potential control of chilling injury in cold disinfested 'E ureka' lemons (Citrus limon). Hot water dips significantly reduced the incidence of chilling injury in fruit stored at 1 degrees C for 28 an d 42 days. Storage at 1 degrees C for 14 days resulted in comparativel y minor chilling injury, so that hot water dips gave little additional benefit. This result is thought to reflect the low incidence of chill ing injury, rather than the lack of effectiveness of heat treatments. Scald damage (surface browning) occurred after 3 min at 53 degrees C. Heat treatments had no significant effect on the incidence of disease at all durations of storage. The rate of fruit weight loss during 7 da ys at 20 degrees C after storage for 14, 28 or 42 days at 1 degrees C was significantly lower in heat- treated fruit.
