Abstract
A novel electrochemical noise (EN) sensor was elaborately designed to detect the metal residue in energy drinks. By calculating the characteristic parameter, noise resistance R n, obtained from the EN data, the tin and iron residue can be semiquantitatively evaluated. In addition, R n was further compared with the inductively coupled plasma mass spectrometer (ICP-MS) results. Accordingly, an interesting relationship was found between the EN data and ICP-MS results. The experimental results reveal that R n can indirectly reflect the corrosion-induced metal release from the packaging materials; a lower R n means a higher metal release. This electrochemical sensor has potential applications in evaluating food safety because of its fast, economic and in-situ features.
