Voltammetric discrimination of skatole and indole at disposable screen printed electrodes.
In this work, we study the electrochemical behaviour of skatole, one of the compounds responsible for the offensive smell in pork meat that is known as boar taint, at different metal and carbon electrodes. We then demonstrate for the first time that skatole and indole, the main electroactive interferent potentially present in real samples, can be discriminated and separately quantified using cheap and disposable screen printed electrodes (SPE). This implies significant progress compared to the colorimetric method reported by Mortensen in 1983.
