In this paper, an electrical technique based on
capacitive sensor was used to predict the moisture content
of sesame, soybean and canola seed. Experiments
indicated that the capacitive properties of studied oilseed
in this research were found to be a function of moisture
content. Hyperbolic regression was performed for
calibration equation extraction that yielded high values
for R2. Result of paired t-test indicated established
calibration formulas for a variety can be used for another
studied variety. In summary, based on the obtained
results from statistical analyses, the design and
performance of this type of sensor is an appropriate
technique for oilseed moisture prediction and the
electrical measurement concurs with obtained values
from oven drying method. Dielectric measurement is a
powerful tool for determining the moisture content and
more practical than time-consuming oven method.
