Knowledge of analytical values in wines is essential to ensure product safety and compliance with legislation, and it is also essential to understand the various technologies in wine production. The aim of this work was to evaluate the analytical parameters of bottled Moravian wines from the Znojmo sub-region, from harvests 2015 and 2016. Basic oenological parameters and biologically active substances were evaluated. Moreover, we evaluated conditions during bottle aging in wines from harvest 2016. The results of the basic analytical values such as total phenolic acid (TPA), total sulfur dioxide (SO2), pH, actual alcohol content (EtOH), and titratable acidity (TA) were in accordance with generally known values in wines and met the legislative requirements within oenological practices. Biologically active substances, such as gallic acid, trans-caffeic acid (TCA), trans-p-coumaric acid (TPCA), rutin, ferulic acid (FA), myricetin, resveratrol, and quercetin were identified. Comparing the analytical values of individual types of wine leads to a better understanding of winemaking technology and the development of wine as such. The subject of the study was also the monitoring of produced grape pomace incurred during wine production harvest 2015 with the indication of possibilities of its further use.

Research objective: development of a high-pressure reactor for researching the process of extraction of grape pomace by the subcritical water and determining the parameters, providing the maximum yield of various target products – biologically active substances; formation of methodological support for raw material preparation, qualitative and quantitative analysis of extracts, produced by the subcritical extraction. As a result of simulation in the ANSYS system of the stress-strain state of the walls of the reactor chamber and a set of calculation operations, a high-pressure reactor was created that meets the requirements. The formed methodical complex for determining the physicochemical properties of extracts and the content of various biologically active substances included methods for preparing samples and determining the yield of dry extractive substances, evaluation of extraction of polyphenols (tannic-catechol complex), evaluation of extraction of reducing substances, identification furfural and gallic acids, estimation of free organic acids in terms of tartaric acid, evaluation of antioxidant activity of extracts). This methodological complex allows us to estimate the physico-chemical properties of the extracted biologically active substances.

The quality characteristics of technical grapes and wines largely depend on the management system of this culture. The aim of the study was to establish the influence of various norms of the load of a grape bush in a self-rooted and grafted culture on the yield, quality of grapes, as well as the aesthetic and biological value of wine products in the conditions of this terroir. The experiment was carried out in 2018-2019 in Temryuk district of Krasnodar region. The objects of research were grapes and wine material of Krasnostop AZOS variety in a grafted and rooted culture with a different load of shoots on the bush. The plantation was established in 2007 according to 3 × 2 m scheme, the formation of the bush was a spiral cordon AZOS-1. The soil of the experimental site is soddy-calcareous, thick, low-humus, light-clayey granulometric composition, formed on tertiary saline clays. The upper horizon (0-60 cm) has favorable agrochemical properties and a sufficient level of fertility. The normalization of the load by shoots of grape bushes cultivated in a self-rooted or grafted culture had a significant impact on the yield and technological qualities of Krasnostop AZOS grape variety during the years of the study. The highest yield result was provided by the variant of own-rooted bushes Krasnostop AZOS with standardized shoots 36 ... 40 pcs/bush - 3.45 kg/bush. The excess yield was significant at the 5% significance level in comparison with the control and other variants of the experiment and amounted to 0.45-0.9 kg/bush. The best ratio of sugar content and titratable acidity (standard glucose value - 4.36) for dry red wines had a variant of own-rooted culture with a load of shoots of 36-40 pcs/bush. In the investigated variants, the highest concentration of phenolic substances was in wine from self-rooted grapes with a load of 36 ... 40 shoots per bush - 4130 mg/dm3. This had a positive effect on the organoleptic evaluation of this sample. The maximum total content of substances from a number of biologically active substances was found in wine from grape raw materials obtained from the grafted culture (134.9 ... 147.9 mg/dm3). According to the results of two years of research, the optimal concentration of biologically active substances in the range of 120-135 mg/dm3, which, in combination with other wine components, is able to provide the best quality of dry red wine. In 2018-2019 from the organoleptic point of view, wine materials from grapes of own-rooted culture proved to be of the highest quality. This advantage over the grafted crop was traced in all variants of rationing the load by the shoots of grape bushes.

Legumes are very rich in phytochemicals and in particular isoflavones. In this work we have developed techniques to get the brewing craft beers made with the addition of Umbrian legumes (chickling and lentils), to verify if the healthy and nutritional characteristic of these product change. The results obtained show that probably during the processes of cooking and fermentation a transfer of the biologically active substances from the “special ingredients” to the finished beer takes place. From healthy and nutritional characterization of the beers important results emerged: an interesting mineral profile and a large content of molecules with antioxidant activity like phenolic compounds (350–630 mg/L). It should also be noted that within the group of phenolic compounds present in these beers were also found interesting amount of isoflavones in particular genistin and daidzin, which in addition to being powerful antioxidants have other beneficial effects and therefore can act in the prevention of cancer, inflammatory, cardiovascular, postmenopausal, cognitive, and immune diseases.

The identification of the diversity of microscopic fungi of lithobiont communities of the Argentine Islands in specimens collected during the 22nd Ukrainian Antarctic Expedition was the purpose of this work. Samples of rock, soil, mosses and lichens of rock micro-habitats of “Crustose lichen sub-formation and fruticose lichen and moss cushion sub-formation” were used in the work. These samples were used for extracting and cultivation of filamentous fungi on dense nutrient media. Determination of physiological and biochemical characteristics and identification of yeast-like fungi were performed using a microbiological analyser ‘Vitek-2’ (‘Bio Merieux’, France). Cultivation of microorganisms was carried out at temperatures from +2 to +37 °C. In results cultures of microscopic fungi of Zygomycota (Mucor circinelloides), Ascomycota (species of the genera cf. Tlielebolus, Talaromyces), representatives of the Anamorphic fungi group (Geomyces pannorum, species of the genera Alternaria, Acremonium, Aspergillus, Penicillium, and Cladosporium) were isolated from Antarctic samples. Microscopic fungi Penicillium spp. were dominated after the frequency in the studied samples (54.5%). Rhodotorula rubra and Candida sp. among isolated yeast fungi, and dark pigmented fungi represented by Aureobasidium pulhdans and Exophiala spp. were identified. The biological properties of a number of isolated fungi (the potential ability to synthesise important biologically active substances: melanins, carotenoids, lipids) are characterised. Mycobiota of rock communities of Argentine Islands is rich on filamentous and yeast fungi similarly to other regions of Antarctica. A number of fungi investigated are potentially able to synthesise biologically active substances. The dark pigmented species of the genera Cladosporium, Exophiala, Aureobasidium pulhdans, capable of melanin synthesis; ‘red’ yeast Rhodotorula rubra (carotenoid producers and resistant to toxic metals); Mucor circinelloides and Geomyces pannorum, lipid producers, are among these fungi. Yeast-like fungi assimilated a wide range of carbohydrates, which will allow them to be further used for cultivation in laboratory and process conditions. The collection of technologically promising strains of microorganisms, part of the Culture Collection of Fungi at Taras Shevchenko National University of Kyiv (Ukraine), is updated with isolated species (strains) of filamentous fungi and yeast – potential producers of biologically active substances, obtained within this study.
