Abstract: In this paper, the process of the freezing and the thawing of the distilled water and the tofu had been studied in the electrostatic field. The experiment results showed that the effect of the electrostatic field on the change of the center temperature of the distilled water were not noticeable in the process of the distilled water freezing and the ice melting in the experiments. The effect of the electrostatic field on the change of the center temperature of the tofu in the process of the freezing and the thawing was also not noticeable, but the shape of the sample tofu has changed in the experiment because of the effect of the electrostatic field. The top was fine and smooth, better than the control抯. There was no split on the top, but the upwarp of the tofu at the bottom of the glass incubator has occurred because of the electrostatic field. The author analyzed that the main reason was possibly that the water in the tofu perhaps moved toward the top of the tofu in the electrostatic field. Thus a further study on this field is needed.
