Two measurement techniques; interactance and reflectance were compared their performing abilities. Partial least square regression was used to develop prediction models for physical and chemical quality of intact persimmon fruit. The following conclusion can be drawn from all experimental results. Vis/SWNIRS was found to be feasible to predict soluble solids content, ascorbic acid, as well as physical quality like fruit firmness. The models from interactance measurement mode provided better prediction accuracy in all parameters. In addition, spectral preprocessing techniques can eliminate or reduce variability of spectral properties unrelated to the spectral property of interest., 新大院博(農)第227号}, school = {新潟大学, Niigata University}, title = {Nondestructive Determination of Postharvest Quality of Persimmon Fruit}, year = {} }
