摘要：

Complex impedance spectroscopy (CIS) is a powerful, nondestructive method to study the electrical properties of biomaterials. The electrical properties of spinach (Spinacia oleracea) leaf powder was used to investigate the moisture content using the nondestructive approach. Frequency-dependent relationships of impedance and capacitance with moisture content in various combinations have been explored to predict the moisture content precisely. It was found that the loga-rithmic function of impedance to capacitance could be used to predict the moisture content precisely in the under -investi-gated frequency range (1-10 MHz) with the highest accuracy, as confirmed by the found statistical support.
