Chapter 20 - Meat and Fish Spoilage Measured by Electronic Tongues

Abstract

Monitoring of meat and fish spoilage by electronic tongues (e-tongue) is a particular application that has been developed at a later stage in comparison with the analysis of other types of foods of liquids. The reason for this delay has been the difficulty of finding measuring methods able to achieve a good contact between the electrodes of the tongue and the samples in order to obtain a good reproducibility of the results. In this chapter we report an overview of work devoted to the use of potentiometric, voltammetric, or impedance spectroscopy electronic tongues in the monitorization of fish or meat spoilage.
