Abstract

In this paper, an automated RF system is presented to find the adulteration in common edible products and liquids. The proposed system is based on measurement of the complex permittivity using a modified rectangular waveguide cavity setup. The developed measurement system is automated to evaluate the percentage of adulteration in the test fluid by measuring the complex permittivity of the adulterated sample and comparing it with the reference data. The designed RF system is able to typically detect a contamination of up to 5% in most of the edible products.
