“…Позже результаты были адаптированы и использованы в различных областях, таких как сельское хозяйство, а именно животноводство (Аронов, 2012), но использование электролизной воды было ограничено коротким сроком хранения. С последними улучшениями в технологиях и благодаря появлению более совершенного оборудования ЭХАР приобрели популярность в качестве дезинфицирующего средства в пищевой промышленности (Pshenko, 2019).…”

Introduction: Electrochemically activated aqueous solutions are widely used in medical institutions, animal husbandry, as well as in large food processing facilities. This work presents a literature review on the use of electrochemically activated solutions in the food industry. These solutions can be used as a safe means for processing food raw materials, equipment, food containers, and surfaces of foodservice facilities. The question of using activated aqueous solutions in relation to foodservice establishments is not fully explored in the scientific literature.Purpose: The aim of the research is to study the possibility of using electrochemically activated aqueous solutions as safe and environmentally friendly means for treating objects in the production environment to eliminate the risk of contamination by microorganisms.Materials and Methods: Surfaces of the production environment were selected as the objects of study, including a table, scales, a knife, a slicer, and a gastronorm container. Sweet pepper fruits of the "Avangard" variety were chosen as non-heat-treated food products. An electrochemically activated aqueous solution of chlorine dioxide and hydrogen peroxide compounds with a concentration of active substances of 0.5 ± 0.05 g/L (Anolyte ANK-SUPER) was chosen as the treatment agent. Microbiological studies were conducted using XLD Agar medium and petrifilms. To assess the effectiveness of treatment, microbiological studies were conducted with the determination of Coliform Bacteria (BGKP) and Mesophilic Aerobic and Facultative Anaerobic Microorganisms (KMAFAnM). To achieve acceptable microorganism counts for counting purposes, the tenfold dilution method was used. The residual active chlorine concentration was determined using the iodometric method to determine the actual concentrations of working solutions.Results: The use of undiluted disinfectant with a concentration of 0.5 ± 0.05 g/L confirmed the effectiveness of electrochemically activated solutions against Coliform Bacteria (BGKP), with a significant reduction in the content of Mesophilic Aerobic and Facultative Anaerobic Microorganisms (KMAFAnM) compared to control samples. However, the results of the experiments suggest that parameter selection is required, specifically the concentration of the disinfectant and the duration of treatment depending on the object. The data obtained from preliminary experiments characterize the potential use of reduced concentrations of the working solution (no less than 0.05 ± 0.005 g/L of active chlorine), but do not confirm the possibility of full-scale application of the used concentrations due to the lack of quantitative data on the degree of contamination of the initial surfaces. The possibility of using the solutions as a single agent for treating both working surfaces and fruit and vegetable products has been demonstrated.Conclusion: As a result of the conducted research, the effectiveness of disinfectants based on electrochemically activated solutions against Escherichia coli bacteria (BGKP) and the reduction of Mesophilic Aerobic and Facultative Anaerobic Microorganisms (KMAFAnM) has been confirmed. In addition, among the possible prospects for research, determining the minimum concentrations and contact times for achieving stable disinfecting effects can be mentioned. The results obtained showed that the use of electrochemically activated solutions ensured the biological safety of treated production objects and surfaces of thermally untreated food products. An alternative method of using electrochemically activated solutions as a universal environmentally friendly agent has been proposed. Thus, in foodservice establishments, an effective "green" technology based on electrochemically activated solutions can be implemented.

“…In this case, in various industries, including the food industry, it is considered appropriate to use electrochemically activated water (ECA-water) solutions (anolyte and catholyte), possessing acidic (pH of 3.0-3.5) and alkaline (pH of 9.0-9.5) properties [9][10][11][12] due to the change in the number of positively charged H+ ions or negatively charged OH − ions with an applied electric field [13][14][15].…”

Background: This article is devoted to the study of the effect of electrochemically activated water (catholyte with pH 9.3) on organic compounds of the plant matrix of brewer’s spent grain in order to extract various compounds from it. Methods: Brewer’s spent grain was obtained from barley malt at a pilot plant by mashing the malt followed by filtration and washing of the grain in water and storing it at (0 ± 2) °C in craft bags. For the organic compound quantitative determination, instrumental methods of analysis (HPLC) were used, and the results were subjected to mathematical analysis. Results: The study results showed that at atmospheric pressure, the alkaline properties of the catholyte showed better results compared to aqueous extraction with respect to β-glucan, sugars, nitrogenous and phenolic compounds, and 120 min was the best period for extraction at 50 °C. The excess pressure conditions used (0.5 ÷ 1 atm) revealed an increase in the accumulation of non-starch polysaccharide and nitrogenous compounds, while the level of sugars, furan and phenolic compounds decreased with increasing treatment duration. The waste grain extract ultrasonic treatment used revealed the effectiveness of catholyte in relation to the extraction of β-glucan and nitrogenous fractions; however, sugars and phenolic compounds did not significantly accumulate. The correlation method made it possible to reveal the regularities in the formation of furan compounds under the conditions of extraction with the catholyte: Syringic acid had the greatest effect on the formation of 5-OH-methylfurfural at atmospheric pressure and 50 °C and vanillic acid under conditions of excess pressure. Regarding furfural and 5-methylfurfural, amino acids had a direct effect at excess pressure. It was shown that the content of all furan compounds depends on amino acids with thiol groups and gallic acid; the formation of 5-hydroxymethylfurfural and 5-methylfurfural is influenced by gallic and vanillic acids; the release of furfural and 5-methylfurfural is determined by amino acids and gallic acid; excess pressure conditions promote the formation of furan compounds under the action of gallic and lilac acids. Conclusions: This study showed that a catholyte allows for efficient extraction of carbohydrate, nitrogenous and monophenolic compounds under pressure conditions, while flavonoids require a reduction in extraction time under pressure conditions.

Introduction. The existing methods of animal fat obtaining have certain disadvantages, hence fat extraction study highly is relevant. Electrochemically activated solutions are known to have a great potential for animal fat extraction. The present paper introduced a new advanced fat obtaining technology based on the principle of electrochemical activation. Study objects and methods. The research featured ostrich fat obtained by wet rendering in water and in an electrochemically activated solution (catholyte) using various processing methods and technological parameters. Standard methods helped define the physical and chemical parameters of the obtained fat samples. Results and discussion. The paper introduced a technological and hardware setup of an ostrich fat production line with the necessary equipment specifications. The research made it possible to define the optimal parameters for fat extraction: the salt concentration for the catholyte = 4 g/100 cm3, voltage = 40–42 V, pH = 11, and redox potential of the catholyte = between –600 and –700 mV. During the fat processing, cell membranes in the electrolyte were destroyed, which inactivated the enzyme system. The obtained combination of physical and chemical factors resulted in ostrich fat of high quality. Fat extraction in an electrochemically activated solution (catholyte) catalyzed the process and increased the fat yield, regardless of the processing temperature. The fat yield exceeded 58% at 55°C and catholyte pH of 11.0. At 95–100°C and pH of 9.5–10.6, it exceeded 95%. Conclusion. The new technology increased the fat yield, maintained its high quality, and reduced the processing cost. Therefore, the developed production line could be recommended for fat extraction of farm animals, depending on the intended use.
