Kanpyo (dried gourd shavings) contains little sugar. We noticed this structure and prepared a desiccating tablet. In the research thus far, the Kanpyo desiccating tablet has demonstrated the ability to absorb 50–60 wt% water under saturated conditions. In this study, we tested the water absorption of the Kanpyo tablet under various conditions of humidity (20%RH ~ saturation). The results show that the Kanpyo tablet absorbed water in more than 40% humidity condition. Furthermore, the Kanpyo tablet suggested adsorption and desorption of the water (humidity control).

Key words: dried gourd, humidity control, water absorption
