摘要：
Analysis by bioelectrical impedance spectroscopy was conducted to pursue the behavior of cell tissues in apple fruits during freezing. The relationships between the parameters in an electrical equivalent model of the cell tissues and the progress of freezing were investigated. The extra- and intra-cellular resistance of the model showed the well correlation with a frozen ratio calculated from Plank's equation and these parameters were found to be useful to detect the beginning and the end of the freezing and the progress of freezing of the cell tissues of agricultural products.
