  • The effects of the ice pack and aluminum coated board in the corrugated boxes for maintaining the quality of fresh oriental melons (Cucumis melo var. makuwa) were investigated. The harvested oriental melons were stored at a temperature of $30^{\circ}C$ for 21 days after placing them in the corrugated boxes treated with control, including ice pack and aluminum coated board. The treatment with the ice pack and aluminum coated board was identified to have maintained the relative low temperature in the corrugated box against the high temperature from the environment. For the storage study of the oriental melon, the treatments with the ice pack and aluminum coated board reduced the respiration rate, the development of external color, and total weight loss. All treatments were also effective in maintaining the firmness and decreasing the decay ratio of the oriental melon as compared to those that were controlled. However, the value of total soluble solids regarding the fruit was insignificantly affected by the ice pack treatment. The results indicated that the application of the ice pack and aluminum coated board in the corrugated box played an important role in maintaining the quality of oriental melons during storage. The combination with the ice pack and aluminum coated board had more effective values on the storage qualities for oriental melons than that with the ice pack only. Based on the results of this study, the ice pack and aluminum coated board were the useful treatments for reducing the loss of quality of the fresh oriental melons in high temperature storage conditions.

  • Background: High temperature damage in ginseng is influenced by shading materials related not only to temperature, but also to light intensity and light quality. To address, this green-colored khaki shading sheet is widely used. As they are recently, developed, there is limited research information about their attributes and use. Methods and Results: The four-layered shading net (FLSN), blue-colored shading sheet (BCSS), aluminum-coated shading board (ACSB), and green-colored shading sheet (GCSS) were installed in the wooden A type of sun-block facilities. Two layered black, shading net was additionally used to cover the facilities since the beginning of June. The average temperature at the facility where different shades were tested was in the order of BCSS ($28.9^{\circ}C$) > FLSN ($27.7^{\circ}C$) > GCSS ($27.6^{\circ}C$) > ACSB ($27.1^{\circ}C$). However, high temperature injury rates were in order: FLSN > ACSB > GCSS > BCSS. Root weight vaired and was in the order: ACSB > GCSS > BCSS > FLSN. Conclusions: High temperature damage is possible not only because of temperature increase, but also due to various environmental light factors. Ginseng high temperature injury was minimal when BCSS or GCSS were used by difference of light quality. Although the root weight was higher in ACSB, it could be vulnerable to high temperature damage. Therefore, we propose using GCSS for ginseng shading.
