Evaluation of the Resistance-Capacitance Method for Detection of Reduced Corn Wet Milling Quality

A procedure using the resistance-capacitance (RC) properties of corn was evaluated for detection of corn that had reduced wet milling quality. In 1991 and 1992, three hybrids were dried at temperatures between ambient and 115$\sp\circ$C in batch dryers. Additional samples were obtained from area elevators in 1992, with temperatures ranging from 52 to 260$\sp\circ$C. A baseline reference relationship was developed between log$\sb $-resistance and capacitance using ambient-dried samples. RC properties of samples dried at temperatures greater than 50$\sp\circ$C were compared to the baseline and the displacement value (DV) determined. Selected drying treatments were wet milled using a laboratory-scale procedure and evaluated. Test weight, 100 kernel weight and kernel density and volume were determined to investigate their influence on DV.
