Modern marketing chains continuously stimulate postharvest technology research to develop and improve techniques for measuring internal defects and nutritional and organoleptic fruit quality attributes. Three relatively new non-destructive techniques to assess pear fruit quality and to determine the optimal harvest date-acoustic firmness sensor, electronic nose and near-infrared spectroscopy-are described here. Tomographic techniques like X-ray computer tomography and magnetic resonance imaging were found to be useful for detecting the incidence of core breakdown, a storage disorder in Conference pears. Both techniques were found suitable to discriminate between cavities, affected and unaffected tissue. An attempt was made to detect internal cavities using a technique based on vibrational modal analysis.
