The room temperature storage time on the influence of dielectric parameters of red globe grape were studied with parallel-plate electrode system in the rang of 50 Hz-1 MHz.The results show that with the increase of frequency the electric conductance and equivalent parallel capacitance increase and the equivalent impedance decrease and the loss coefficient and quality factor in 25 kHZ reached Minimum and maximum respectively.In the same frequency,the equivalent impedance and quality factor decrease and equivalent parallel capacitance,loss coefficient and the electric conductance increase with storage time increasing.Analysis the above result shows that the room temperature storage time on the electrical characteristics of red globe grape is bigger,and there is a strong correlation between the electrical characteristics parameters and electric field frequency.
