Outline of Final Research Achievements

The objectives of this study were to examine the changes in permeability and lipid peroxide of biomembrane in postharvest spinach leaves, and to develop nondestructive measurement technology for those properties using visible and near infrared spectroscopy. Results revealed that membrane lipid peroxide was gained prior to the increase in membrane permeability, suggesting that there is a threshold in the accumulation of lipid peroxide to increase membrane permeability. It was possible to construct calibration models having an R-square value above 0.5 for rate constant of ion leakage and malondialdehyde equivalent. This study gave the possibility of freshness evaluation of fruits and vegetables based on health assessment of the biomembrane using visible near-infrared spectroscopy.
