To obtain the respiratory characteristic of agricultural product, the controlled atmospheric storage was conducted by using the desiccator at 5°C, 10°C and 25°C. As the experimental sample, mature green tomatoes and red ripe tomatoes were used. In a closed system, ripening was inhibited for tomato stored in low oxygen atmosphere, and the pseudo-periodic stop was observed at the critical respiration. It was confirmed that at 5°C tomatoes suffered chilling injury in the low oxygen atmospheric storage. Moreover, the oxygen permeability of film package was designed from the critical respiration rate calculated from the data by using the desiccator and it was examined on the effective storage desiccator. The results indicated that the change in surface color of tomato in the packaging film was inhibited. And it was confirmed that both the desiccator and film in the same storage condition showed the same tendency in the storage effect. Therefore, it is also confirmed that the packaging film with oxygen permeability 4, 300ml/m²·24h could be applied for the agricultural products.

Evaluation system of fruit appearance, available on Internet, was constructed by using a Java applet to analyze the shape and color that are the main factor of a fruit quality. Since quantified appearance data of fruits, that had been very difficult to calculate heretofore, were easily created and accumulated to the database by this system, the database of fruit appearance was automatically constructed.<br>In this study, the fruits of grape 'Aki Queen' was selected as a sample and its shape and color was analyzed by this system. As a result, the determination of standard shape was made and the temporal change of coloring was also clarified through the quantification process of the shape and color. From these, this system was shown to be useful to the appearance evaluation of a fruit, where not only the binding of the evaluation standard is difficult but also uniform evaluation is difficult to make.

Considering the surface color change in ripening of tomatoes the color appearance by the production of pigments, the purpose of this study is to examine the color appearance mechanism by measuring the surface color change, to find the relationship between the color development and the production of pigments. As the results, it was found the surface color changed from the special points upon the radial wall of the pericarp. Next, the changing rate of the chlorophyll and the lycopene were calculated by assuming that the carotene content was constant. The calculated values showed the similar tendency to the extracted values of the pigments. This result is suggested that the hue was suitable for the analysis of the production of pigments.

Color image processing system was constructed to manage the surface color of agricultural products, and several problems in measuring the surface color was examined. Two problems, that is, the setting of condition of illumination which is also an issue in general image processing, and the difference of the color sensation between the visual sense of human and the sense of camera, were dealt with HSL color space. On the problem of illumination, the influence of the quantity of light and the camera angle were examined, and it was confirmed that hue (H) and saturation (S) were not affected by uneven illumination. By the experiments using ripe bananas and immature tomatoes as samples, it was found that the shade of the surface color during post-ripening appeared on the H, and the shade of the surface color in later ripeness appeared on the S.
