“…As a low cost and simple technique, electrical impedance spectroscopy (EIS) has been widely used to non-destructively characterise fruits and vegetables. Compared to other new microscopic techniques, the EIS is considered competitive because of the advantage in vivo detection of early changes both in physiological and structure stress [17,18] . It has been recently applied in the characterisation of fruits and vegetables in a very high frequency range [6,14,[18][19][20][21][22] .…”

Ripening is important to tomato quality, taste and nutrition. In this study, the maturity of plant-fruit was on-line investigated based on electrical impedance spectroscopy (EIS). The electrodes with sensing unit for contact force between samples and electrodes were designed. After fruits turn into green-white, impedance measurements were conducted on the fruit samples at various ripening stages in the range of 1 Hz to 1 MHz. The optimal frequencies (100 Hz, 1 kHz and 1 MHz) for maturity assessment were selected and five electrical impedance parameters at three sensitive frequencies were determined. The equivalent circuit model with CPE was developed and the model performance was evaluated. The soluble solid content and pH of fruit were determined and analyzed to explain the variations in EIS parameters sufficiently. Results showed that the impedance, phase angle, resistance, reactance and capacitance increased with the progression of maturity. The selected impedance parameters could be used to classify tomato samples into immature class or mature class with the accuracy of 88.3%. Impedance analysis for different samples from the same branch demonstrated that the ripening stage of all other samples could be predicted and assessed by the impedance spectroscopy from one sample.

“…The α-dispersion (10 Hz to 10 kHz) is related to the phenomena of ionic diffusion of the cell membrane and the counterion effects, the β-dispersion (10 kHz to 100 MHz) is related to the polarization phenomenon of cell membranes, and the γ-dispersion (in GHz order) is related to the polarization of water molecules [3]. Properties of electrical impedance have been reported to understand the nature and behavior of cell [4][5][6][7][8], bacteria detection and identification [9,10], identification of beverages and food ingredients [11][12][13][14][15][16], and so on. In the medical field, BIS is used to characterizations of serum and blood [17][18][19], identification of body composition and disease [20][21][22], and to assist the process of diagnosis and functional electrical stimulation of the body [23][24][25].…”

Bioelectric impedance spectroscopy (BIS) has been widely used to study the electrical properties of biological tissue based on the characteristics of the complex electrical impedance dispersions. One of the problems in using the BIS method is the length of time required for the data acquisition process and possibly data analysis as well. In this research, a compact and work rapidly BIS instrumentation system has been developed at a low cost. It is designed to work in the frequency range of 100 Hz to 100 kHz, which is generally used in the fields of biophysics and medical physics. The BIS instrumentation system is built using several integrated modules. The modules are an AC current source to produce a selectable injection current; a data acquisition system to measure voltage, current, and phase difference rapidly and simultaneously; and software to calculate and display measurement results in the form of Bode and Nyquist plots in real time. The developed BIS system has been validated using a simple RC circuit as the sample being tested. The average time needed in the process of data acquisition and analysis until the formation of impedance dispersion curves in the form of Bode and Nyquist plots, for 54 sample frequencies, is less than one minute. The system is able to identify R and C values of the sample with a maximum error of 1.5%. In addition, some simple application examples are also presented in this paper.

“…Today the most widespread methods of vegetables cleaning are mechanical and steam ones [4]. But despite the fact that these two methods have many advantages comparing with other ones, shortcomings, typical for each of them, need a detail study of these ways for their more effective use at enterprises of restaurant economy [5].…”

Elaboration and improvement of the process of raw material cleaning is an urgent scientifically technical process. The one of most prospective directions of vegetables cleaning process intensification is the elaboration of combined methods of their cleaning. The improvement of tubers cleaning process is based on the combination of thermal processing of sunroot tubers by steam and the process of further mechanical additional cleaning. The experimental studies of the influence of parameters of the process of sunroot thermal processing by steam on a tuber surface layer transformation were carried out. The influence of the steam pressure and the duration of the process of tubers thermal processing on the depth of the thermal processing of tuber surface layer and also on the effectiveness of the peel separation were studied. At the same time there were realized the studies as to the influence of the duration of tubers mechanical additional cleaning process on cleaning quality parameters. The experimental apparatus and correspondent method that allow to carry out investigations of the combined process of sunroot tubers cleaning with a possibility to determine the influence of all its parameters on the percent of raw material losses and cleaning quality were elaborated. Rational regimes of the combined process of sunroot tubers cleaning were established.
