Water property can be changed by various factors such as thermal energy, electromagnetic waves, and dissolved gases, which influences on human health. The specific effects of water mediated by other factors such as advanced ceramics and microwave are still vaguely known. This study examined the effect of water heated in the microwave oven on the soybean germination rate compared to the water heated on the gas range using the functional ceramic vessel (FCV) coated with ferromagnetic material at the external bottom surface. First, to investigate the differences of FCV and general ceramic vessel (control) after heating in the microwave oven, surface temperature of an empty FCV and water temperature and pH were time-dependently measured. In result, the bottom temperature of FCV was significantly higher (176.7°C after heating for 4 minutes) as compared with the control (75.7°C). The temperature and pH also showed a trend of slight increase in FCV as compared to the control. Second, using the FCV in boiling the water, a higher germination rate was shown using water boiled in microwave (96.0%) as compared to using water boiled in gas range (85.7%). Taken together, these results suggest that the FCV together with the electromagnetic wave may change the water property which may have an effect on human health.
