Postharvest quality changes as affected by storage humidity in 'Niitaka' pear fruit.

The effect of storage humidity (high or low) on postharvest fruit quality was examined in Pyrus pyriforia [P. pyrifolia] cv. Niitaka stored at 2 deg C. At low RH (50-80%), fruit firmness decreased much faster than under high RH (90-95%). Weight loss was up to 14.5% of initial value after 5 months of storage at low RH, whereas it was only 2.96% at high RH even after 10 months of storage. TSS and total acidity sharply increased after 3 months of storage at low RH. At low RH, fruits developed a rough cuticular layer, a dark skin colour and cells in the epidermal layer became smaller in size as storage period was extended. Higher concentrations of ethanol and acetaldehyde, resulting in 'off-flavour', were detected in fruits stored under low RH. Market quality of Niitaka fruits could be maintained for 10 months if fruits were stored at high RH.
