Interpretive Summary:

Technical Abstract: Microwave moisture sensing provides a means to nondestructively determine the amount of water in materials. This is accomplished through the correlation of dielectric constant and loss factor with moisture content in the material. In this study, linear relationships between a density-independent function of the dielectric properties and moisture content of minced Vidalia onions. Multiple slopes were used dependent on prediction moisture range. This allowed prediction of moisture contents between 6% and 92%. Results showed prediction of moisture content with high accuracy. The measurements and techniques presented in this study constitute a foundation for the development of a stand-alone sensor.
