“…The impedance characteristics of biological tissues are well correlated with properties such as texture and fat content (Ando et al, ; Traffano‐Schiffo, Castro‐Giraldez, Colom, & Fito, ; Zavadlav et al, ; Zollinger, Farrow, Lawrence, & Latman, ). Different kinds of meat have different quality characteristics, such as different fiber thickness, texture, and fat content.…”

To establish a rapid, convenient, and low‐cost method to assess the quality of Atlantic salmon, we analyzed the impedance between 10–1 and 105 Hz for Atlantic salmon/rainbow trout, chilled/frozen‐thawed salmon, and fresh/stale salmon. We combined chemometrics with impedance properties to create a multi‐quality index for Atlantic salmon. The accuracy of all three models established can reach 100% in distinguishing Atlantic salmon from rainbow trout and distinguishing chilled salmon from frozen‐thawed salmon. We applied a partial least squares method to create a quantitative prediction model of bioimpedance spectroscopy and the value of total volatile basic nitrogen. The correlation coefficients of the training and test sets were 0.9447 and 0.9387. Our results showed that the combination of impedance properties and chemometrics was a simple and effective application to evaluate Atlantic salmon quality.

“…The electrode was inserted in 50 mM and 142 mM NaCl solutions to assess the electrode polarisation that was found to be pronounced below 5 kHz and that diminishes at higher frequencies. [9,16] The electrode array was positioned transversally to the direction of the muscle fibres. The impedance module (|Z|) and phase (φ) were measured at 200 frequencies from 100 Hz to 100 MHz, however, we were focused on the frequencies above 5 kHz where electrode polarisation gradually diminishes.…”

“…The impedance changes with the alternations of the chemical composition among the samples (water/ lipid content), during the post-mortem period [9] or as a consequence of freezing.

“…electrical conductivity and permittivity), and electrode geometry. [9] Although impedance measurements are fast and easy to perform, challenges with the anisotropy of the samples and electrode polarisation should be overcome. Moreover, as salt is not homogeneously distributed through a meat or fish sample at the end of the salting process, the electrode should preferably be able to measure not only the surface, but also the depth of the samples.…”

The aim of this study was to test the applicability of bioelectrical measurements and a needle-type multi-electrode array in evaluating salt and moisture content of structurally heterogeneous food samples, such as fish. Impedance measurements were performed at different frequencies in order to find the most appropriate range, where impedance module and/or phase angle are the most sensitive to salt and moisture content. The salt, moisture, and water phase salt (WPS) of the salted rainbow trout samples were successfully evaluated by the impedance module measured at 50 kHz (AdR2 > 0.85). Due to rapid and non-destructive analysis coupled with low cost device design, this method for determination of salt and/or moisture has potential as the quality control technique for the fish industry.

“…However, TVB-N detects (at least in fish) later stages of quality deterioration during storage [11] whereas cephalopods muscles have the tendency to remain microbiologically less spoiled [4]. Other parameters, as color changes [12,13], the content/concentration of free amino acids [14], and protein solubility [15][16][17] are all well correlated with spoilage in squids, hence are potential indicators of spoilage.…”

This study evaluates the quality of chilled squid Loligo vulgaris by non-destructive measurements of bioelectrical impedance from the first post-mortem day under controlled conditions. Squid samples were stored at 4.5 °C and 55% of relative humidity for 11 days. Impedance magnitude (|Z|) and phase (φ) at 200 frequencies (100Hz to 100MHz) were measured using an Agilent 4294A Precision Impedance Analyzer with needle-type multi-electrode array on days 1, 2, 3, 4, 5, 8, 9, 10, and 11 of storage. The changes in color, sensory properties, total volatile nitrogen, pH, and water holding capacity were also determined. The obtained results indicated that the samples could be classified into five to six distinctive groups by measuring the electrical parameters at frequencies close to 5MHz. In general, φ is less dependent on temperature and measurement setup than |Z|, while records at 5MHz correlate well with the days of storage (R2 = 0.968). The data imply that it is only possible to estimate the length of storage for the samples with measurements of phase angle, which can be useful for the development of new analytical instruments. Biosensors have a practical industrial application, as it is demonstrated that bioelectrical impedance data correlates well with the days of chilled storage.
