Abstract
ABSTRACT By electrical measurements on a parallel-plate capacitor with a peanut kernel between the plates, the moisture contents of single kernels were estimated and compared with moisture contents obtained by a standard oven drying method. Capacitance, dissipation factor, and phase-angle measurements were made for each kemel in the moisture range from 5% to 15% with an impedance analyzer at two frequencies, 1 MHz and 4.5 MHz. The moisture contents of kernels from several different moisture lots were predicted using these measured values in an empirical equation. The predicted values were within 1% of the oven values for 97% of the peanut kemels in this moisture range.
