Abstract :
Dielectric spectroscopy studies on honeydew melons revealed a high correlation with soluble solids content for a complex-plane plot of the dielectric properties. In this paper, a new dielectric spectroscopy measurements were carried out on watermelons to study the correlation of dielectric properties, measured on the surface of the melons and on the internal tissues, with soluble solids determinations on tissues from the same melons.
