Evaluation of fish spoilage by means of a single metal oxide sensor under temperature modulation

In this paper the feasibility of using metal oxide gas sensor technology for evaluating spoilage process for sea bream (Sparus aurata) is explored. It is shown that a single sensor under temperature modulation is able to find a correlation with the fish spoilage process. Results are obtained in real frigorific storage conditions; that is, at low measurement temperatures with variations of relative humidity.
