Kanpyo (dried gourd shavings) consists of a lot of fiber and 95% water. We noticed this structure and performed the basic preparation of a new desiccating tablet. In the research thus far, the Kanpyo desiccating tablet demonstrated the ability to absorb 50–60 wt% of water. However, mold grew on the surface of the Kanpyo tablet after it absorbed the water. In this study, we examined how to prevent this mold. First, Kanpyo powder was added to five kinds of preservatives individually. Next, Kanpyo powder with the preservative was machine pressed. The water-absorbing performance of the Kanpyo tablet with the preservative was confirmed in a saturated container. The results show that tablets with and without the binder continued absorbing water for 350 hours. Additionally, mold was not present only in the tablet that included ethyl p-hydroxybenzoate.

Key words: Kanpyo / dried gourd / desiccating tablet / preservative
