Non-Destructive Evaluation

摘要: In this chapter an overview will be given of non-destructive techniques for measuring quality attributes horticultural produce. Vision-based to measure external appearance discussed, as well tomographic inspect internal defects. The emphasis on magnetic resonance imaging and X-ray computed tomography. Impact acoustic impulse response mechanical properties fruit reviewed. relationship between destructive measures firmness addressed, the limitations so-called index when applied non-spherical fruit. Spectroscopic such soluble solids content vegetables introduced. Novel time spatially resolved spectroscopy estimation light absorption scattering vegetable tissue, NIR hyperspectral techniques, discussed. Finally, novel mass spectrometry based electronic noses rapid measurement aroma described.
