The relationship between the ice polycrystalline structure and the dielectric properties of a frozen gelatin gel were investigated. The Micro-Slicer Image Processing System (MSIPS) was applied to measure the diameter, the perimeter density and the number density of ice crystals. The dielectric property of frozen gelatin gel at various freezing rate was measured in the frequency range of 100Hz to 100kHz at –40°C. The characteristic value of dielectric property, σ0 and ε0-ε∞ have good correlation with structural parameters of ice crystals, such as diameter, perimeter density and number density, while other characteristic value, the relaxation time, τ has no relation to the structure of ice polycrystalline. The resu1ts showed that the possibility of non-destructive measurement of ice structure by dielectric property.
