Abstract

Inklusjoner slik som inkapslede parasitter (21) og bedervelse i matvareprodukter slik som fiskefileter (1) påvises ved å senke matvareproduktene i et bad av en elektrolytt (5), slik som en saltløsning, hvilken har i det vesentlige samme elektriske ledningsevne som det ukontaminerte matvareprodukt. En elektrisk strøm (I) som føres gjennom elektrolytten (5) passerer også gjennom matvareproduktet (1). Perturbasjoner i det resulterende magnetiske felt hvilke frembringes av diskontinuiteter i ledningsevne ved grensene for inklusjonene eller for den bedervede artikkel hvilken har vesentlige annerledes ledningsevner enn den for elektrolytten og ubedervede matvareprodukter, frembringer en indikasjon på tilstedeværelsen av kontaminasjonen. Perturbasjoner i det magnetiske felt ved kantene av beholderen (43) kanselleres ved å rette strømmen (I) i en første retning og tilbake over beholderen (43) i motsatt retning gjennom en kanselleringsleder (25).
