Rheological and electrical properties of agricultural products were measured to analyze the mechanism of freeze-injury. Dynamic elesticity and dynamic viscosity, measured by vibrating-reed method, were largely decreased through freezing-thawing. Freezing-thawing also caused substantial decrese in electrical impedance at the frequency range around 100 kHz, showing the freezing damage on plasma membrane of agricultural products. This seemed to cause the loss in turger presure of cells, which explained the large change in Theological properties after freezing-thawing. Rheological properties of eight kind of agricultural products, such as Japanese raddish, potato, carrot, apple, pumpkin, etc., were measured and compared with one another before and after freezing.
