Abstract

In this work, a nondestructive method based on the dielectric properties for the measurement of melons´ sugar was presented. Resistance and capacitance of melons were obtained to predict the sweetness, using the genetic algorithm (GA) to optimize the parameters of its nuclear function (RBF), adopting Least Squares Support Vector Machines (LS-SVM) to obtain the sugar. The results showed that the precision was high under low cost condition, which could make available for use in the development of rapid and nondestructive sensors of melons.
