Non-invasive measurements of post-mortem changes in dielectric properties of haddock muscle – a pilot study Original Research Article

Significant changes can be measured in the electrical properties of organs and muscle during ischemia. This will undoubtedly form the basis of new diagnostic tools and tools for assessing food quality in the future. In this paper, we present measurements of the electrical properties of haddock muscle from 1 Hz to 100 kHz as a function of time after the fish was sacrificed. Clear alpha and beta dispersions were found. Most of the alpha dispersion disappeared after a few hours. The low frequency resistance of the beta dispersion increased during the first 5 h as the fish went into rigor, and then decreased as cell destruction developed.
