The electrical measurements are utilized in many works to determination of fruit properties. Microscopic and macroscopic non-homogeneities of biological materials affect their electrical properties. These properties of fleshy fruit are utilized at non-destructive determination of their ripeness or sugar content. The temperature and moisture content have important role at the selection of suitable regime of the storage. These are the most important parameters that influence physical and physiological processes which run in the stored plant products. Dried fruits with very low moisture content have good assumptions for the long storage. Samples of dried fruits were delivered by Faculty of Agriculture of University of Novi Sad, Serbia. Electrical properties (impedance, electrical capacity) were measured by LCR meter GoodWill LCR-819. Measurements had been realized at frequencies from 100 Hz to 200 kHz. Frequency dependencies of impedance and electical capacity were determined for all samples. The capacitance and impedance decrease powerly in dependence on the frequency.
