Abstract
Internal temperature equalization of the bovine metatarsal with cortical and cancellous bone during microwave irradiation was investigated. In our previous study, bovine bone more rapidly than methods of conventional thermal process, because the bone was heated from deep part during microwave irradiation. Moreover, humidifying the surface of the bone reduced distribution in the internal bone temperature. Internal temperature equalization in bovine metatarsal bone by microwave irradiation was not successful, but in bovine femoral head (cancellous bone) and diaphysis (cortical bone), a temperature of 80±10℃. So in this study, industrial microwave oven was used. After refining the system using an industrial microwave oven, an internal temperature of the bovine metatarsals (containing both cancellous bone and cortical bone) could be maintained at 82±3℃ and processing time. These results suggest that thermal processing for disinfection using microwave irradiation can heat the bone more quickly by equalizing the internal temperature.
