Design of a low-cost non-destructive system for punctual measurements of salt levels in food products using impedance spectroscopy

Electrical Impedance Spectroscopy for Quality Assessment of Meat and Fish: A Review on Basic Principles, Measurement Methods, and Recent Advances

“…Good results were also obtained for salt content prediction of salted meat based on EIS [57,78,79]. It was also found that minced samples had better prediction accuracies than block samples, which indicated that salt homogeneously distributed within meat favorably impacts prediction accuracy.…”

“…The parasitic impedance decreases with frequency increasing; thus it can be ignored when frequency is high in bipolar measurement system [17]. Material and configuration of electrodes have an impact on electric field loaded on the tested biological tissue and are important factors in EIS measurements [57,58].…”

“…Sun et al [17] estimated freshness of carp based on EIS morphological characteristic with a pair of platinum (Pt) electrodes ( Figure 6(a)). Masot et al [57] used a coaxial needle electrode ( Figure 6(b)) in measurement to predict salt content in cured ham or pork loin. The electrode was made of a hollow needle and an isolated wire inside the needle, which were both made of stainless steel.…”

Glyphosate detection by voltammetric techniques. A comparison between statistical methods and an artificial neural network

“…This is because the flow of the current through the dissolution is a function of the applied voltage and the chemical concentration in the dissolution. The measurements have been made with a device developed by the Institute of Molecular Recognition and Technological Development (IDM) called FraPlusMini [22], which is capable of running tests for Potentiometry [23], Amperometry [23,24], Pulse Voltammetry and Cyclic Voltammetry [25], and has been successfully used in food [26][27][28], water analyses [29] and also in the determination of environmental parameters [30]. The system consists of a software application that runs on a PC and electronic equipment.…”

Sensores electroquímicos tipo lengua electrónica voltamétrica aplicados al control medioambiental y a la industria alimentaria

“…A raíz de nuestro interés en el diseño del sistema de detección 195,196,197,198,199 hemos desarrollado una lengua electrónica voltamétrica simple que se ha utilizado para caracterizar el tratamiento de las aguas afluentes y efluentes para una planta depuradora de aguas residuales domésticas. El sistema propuesto consiste en una array de electrodos metálicos formado por Au, Pt, Ir, Rh, Ag, Cu, Ni y Co y su uso como electrodos de trabajo en los experimentos de voltametría.…”
