AB  - The phenolic composition and antioxidant activity of wine and fermented pomace (FP) from Cabernet Sauvignon grapes harvested at three ripening stages were evaluated using LC-MS/MS and spectrophotometric analyses. An investigation of grey mold’s (Botrytis cinerea) influence on wine phenolic content modulation was conducted as well. Finally, the influence of the plant’s ripening stage on the dynamics of the phenolic compounds extracted from wine and FP obtained from fully ripe grapes was evaluated. In this study, the content of catechin, epicatechin, quercetin, and p-coumaric, gallic, and syringic acids was analyzed. Wine and FP were obtained after extended maceration during the spontaneous and inoculated fermentation of fully ripe grapes. When comparing the wine and FP obtained from véraison, fully ripe, and overripe grapes, catechin was the most abundant in wine (40.13 ± 3.25 mg/L) and quercetin in FP (10.96 ± 0.14 mg/kg). A decrease in analyzed phenolic compounds was noticed in wine produced from grapes affected by Botrytis cinerea, and the highest depletion was found for quercetin. The use of a winemaking technique that involved differing maceration periods and inoculation using yeasts as well as spontaneous fermentation significantly modulated the phenolic content of derived wines and FP. The dynamics of the phenolic compounds extracted into wine, evaluated using a principal component analysis (PCA), highlighted contents of catechin and epicatechin. After a decrease in maceration, the PCA revealed a notable content of gallic and syringic acids, as well as quercetin, in samples of FP. This study offers a perspective for future research and the development of functional food with a high content of phenolic compounds originating from red grape products, such as wine and fermented pomace.

AB  - This study aimed to show aromatic profile of wines produced from two autochthonous grape cultivars Krstač (K) and Žižak (Z). During the wine production two enzymatic preparations (EP) Lallzyme cuvee blanc (CB) and Lallzyme enzymatic preparation β (EB) and different time of skin contact (4 and 8 h) were applied. Aromatic compounds were detected by GC/FID–MS ana­lysis. Significantly higher content of total detected aromatic compounds com­pared to appropriate controls (168.54 and 161.72 mg L-1) was observed for K EB4h (176.33 mg L-1) and Z CB4h (177.29 mg L-1) wines. Skin contact and usage of EP mostly increased content of 2-phenylethyl and isoamyl alcohols. Wines from both varieties showed higher content of hexanoic and octanoic acids compared to the control. It is interesting to emphasize that content of esters that are responsible for fruity aroma of wine which is important for plea­sant taste (isoamyl acetate – banana, ethyl hexanoate – ripe banana, 2-phe­nyl­ethyl acetate – powerful fruity rose like) were increased in all samples com­pared to the controls. The highest grades, after sensory evaluation, were obtained for K EB 8h (18.0 out of 20.0) and Z CB 8h (18.2 out of 20.0).

AB  - This study aimed to evaluate, in vitro, the antioxidative potential of fruit wines produced from berry fruits (i.e., black chokeberry, blueberry, blackberry, and raspberry), cherry, and apple by different technological processes. For this purpose, the activities of antioxidant enzymes (catalase, glutathione peroxidase (GPx), and superoxide dismutase (SOD)) and malondialdehyde (MDA) content as a marker of membrane damage were determined in wine-treated synaptosomes with hydrogen peroxide-induced oxidative stress. All studied wines induced increased antioxidant enzyme activities and decreased MDA levels compared to hydrogen peroxide-treated synaptosomes (i.e., control). The highest SOD activity was observed in synaptosomes treated with blackberry wine (6.81 U/mg), whereas blueberry wine induced the highest catalase and glutathione peroxidase activities (0.058 U/mg and 0.017 U/mg, respectively). Black chokeberry proved to be the best in lipid peroxidation protection with the lowest MDA value (1.42 nmol/mg). Finally, principal component analysis and hierarchical cluster analysis additionally highlighted a higher antioxidant capacity of wines produced from dark-skinned fruits (i.e., blackberry, black chokeberry, and blueberry). The results suggest protective effects of the fruit wines against oxidative damage, and, accordingly, their promising application as functional food.

AB  - Bio-electronic tongue was linked to artificial intelligence processing unit and used for classification of wines based on carboxylic acids levels, which were indirectly related to malolactic fermentation. The system employed amperometric biosensors with lactate oxidase, sarcosine oxidase, and fumarase/sarcosine oxidase in the three sensing channels. The results were processed using two statistical methods - principal component analysis (PCA) and self-organized maps (SOM) in order to classify 31 wine samples from the South Moravia region in the Czech Republic. Reference assays were carried out using the capillary electrophoresis (CE). The PCA patterns for both CE and biosensor data provided good correspondence in the clusters of samples. The SOM treatment provided a better resolution of the generated patterns of samples compared to PCA, the SOM derived clusters corresponded with the PCA classification only partially. The biosensor/SOM combination offers a novel procedure of wine classification.

AB  - The focus of this study was to investigate the effects of clones (subvarieties) of autochthonous Serbian grape variety Prokupac, along with the influence of vinification method on the content of transand cis-resveratrol as well as on total phenolic content (TPC) in wines. Wines were made from four clones of Prokupac variety (PR1, 40/1, PR6 and PR7) by application of different periods of maceration duration (1, 5 and 10 days). The effects of different species of selected wine yeasts and glucosidase enzymes on the quantity of resveratrol and TPC in wine made from PR6 variety were also investigated. The content of trans-resveratrol varied from 0.27 mg/L to 1.46 mg/L. The highest content of resveratrol was determined in Prokupac clone PR6, and the lowest in PR7 clone. An increase in resveratrol and TPC content was observed in all clones when the duration of maceration was prolonged. Wine produced by application of b enzyme preparation and 299 yeast had the highest concentration of total resveratrol (4.23 mg/L). The TPC was the highest in the wine made by combined application of yeast 299 and OE enzyme. The obtained results showed that by adequate selection of varieties, prolonged duration of maceration, application of appropriate species of yeast and enzyme preparations, it is possible to increase the content of resveratrol and other phenolic compounds in wine.

Vina su proizvedena od četiri klona sorte Prokupac (PR1, 40/1, PR6 i PR7) primenom različitih dužina trajanja maceracije (1, 5 i 10 dana) za svaki klon. Takođe je ispitivan uticaj različitih izabranih kvasaca i enzimskih preparata glikozidaza na sadržaj rezveratrola i SUP u vinima proizvedenim od klona PR6. Sadržaj transi cisrezveratrola je određen HPLC metodom sa UV detektorom uz prethodnu tečno čvrstu ekstrakciju (SPE). Određivanje SUP je urađeno metodom po FolinČokalteu. Sadržaj transrezveratrola je bio od 0,27 mg/L do 1,46 mg/L. Najviši sadržaj rezveratrola je bio u klonu PR6 dok je najniži PR7. Povećanje sadržaja rezveratrola i SUP je primećeno kod svih klonova kada je maceracija duže trajala. Vino proizvedeno primenom enzimskog preparata glikozidaza b i kvasca 299 je imalo najviši sadržaj ukupnog rezvertrola (4,23 mg/L).

AB  - This study aimed to estimate the potential of the selected berry (strawberry) and drupe (apricot, plum and sweet cherry) fruits as the substrates for the production of new fruit wines enriched with phenolic compounds. Sweet cherry wine (cultivar Burlat) stood out both for the profound content of phenolics (followed by their chemical profile) and potent anti-DPPH radical activity. The same fruit wine samples exhibited high redox potentials, slightly lower than strawberry and plum wine samples. Therefore, sweet cherry cultivar Burlat may be well recommended for development of novel fruit-based products endowed with naturally occurring phenolics. In any case, the remaining four cultivars are also worth further research efforts, particularly apricot cultivar Keckemetska ruza, which is one of the representatives of greatly underestimated fruit type thus far as a substrate for the production of the relevant fruit wines.

AB  - Introduction - Fruit and their products, including fruit wines, represent a rich source of natural bioactive compounds. This study focusing on fruit wines (prepared from commercially grown fruits by Serbian producers) has included the investigation of their chemical composition and biological activity. Materials and methods - Black chokeberry, blueberry, raspberry, blackberry and cherry were used for wine production by innovative vinification procedure, with or without using sugar and enzymatic preparation glycosidase, respectively. Selected phenolics were identified and quantified by UPLC/MS-MS analysis, while Total Phenolic Content (TPC) was determined by the Folin-Ciocalteu method. In addition to this, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and FRAP (Ferric Reducing Ability of Plasma) methods were applied for the preliminary evaluation of anti-DPPH radical activity and redox potential respectively at in vitro conditions. Results and discussion - Among the fruit wines examined within this study, the blackberry one stood out for profound FRAP (115.23 mmol L-1 Fe2+), DPPH (1.11%) and TPC values (2,395 mg GAE L-1). On the other hand, the raspberry wine showed the lowest potential towards the aforementioned parameters. Using principal component analysis, these fruit wines were chemically differentiated, according to the predominant phenolic compounds. Conclusions - All fruit wine samples displayed a good antioxidant potential with the blackberry one being most potent. Such a finding is of particular importance for Serbia as one of the leading producers of this edible fruit both in Europe and rest of the world.

AB  - alpha-Glucosidase inhibitory activity (AGL) of fruit wine samples made from blueberry, black chokeberry, blackberry, raspberry and sour cherry cultivars grown in Serbia was studied using an microvinification procedure. More precisely, both sugar and enzyme were added to the fruit must before fermentation for half of the samples. This increased the extraction of phenolic compounds. All the samples showed higher bioactivity compared to acarbose, the compound used as a positive control. Blueberry (IC50 similar to 27 +/- 1 mu g/ml) and black chokeberry (IC50 similar to 28 +/- 1 mu g/ml) wine samples had the highest values regardless of the vinification method. In addition to this, chlorogenic and caffeic acids were recognised as their key AGL bioactives. Taken all together, the fruit wine samples or their lyophilised extracts may be considered as complementary medicine supplements of potential interest for the control of postprandial hyperglycemia.

AB  - BACKGROUND: Fruit wines are well known for their profound health-promoting properties including both enzyme activations and inhibitions. They may act preventive in regard to diabetes melitus and other chronic diseases. Objectives: Potential alpha-glucosidase inhibitory activity of fruit wines made from blueberry, black chokeberry, blackberry, raspberry and sour cherry was the subject of this study. Method: In order to increase the alcohol content due to enriched extraction of total phenolics, sugar was added in the fruit pomace of the half of the examined fruit wine samples. Results: Compared with acarbose used as a positive control (IC50 = 73.78 mu g/mL), all fruit wine samples exhibited higher alpha-glucosidase inhibitory activity. Indeed, blueberry wine samples stood out, both prepared with IC50 = 24.14 mu g/mL, lyophilised extract yield 3.23% and without IC50 = 46.39 mu g/mL, lyophilised extract yield 2.89% and with addition of sugar before fermentation. Chlorogenic acid predominantly contributed to alpha-glucosidase inhibitory activity of the blueberry, black chokeberry and sour cherry wine samples. However, ellagic acid, a potent alpha-glucosidase inhibitor possessing a planar structure, only slightly affected the activity of the blueberry wine samples, due to the lower concentration. In addition to this, molecular docking study of chlorogenic acid pointed out the importance of binding energy (-8.5 kcal/mol) for the inhibition of the enzyme. Conclusion: In summary, fruit wines made from blueberry should be primarily taken into consideration as a medicinal food targeting diabetes mellitus type 2 in the early stage, if additional studies would confirm their therapeutic potential for the control of postprandial hyperglycemia.

AB  - The composition and content of individual phenolic compounds in various fruit wines and overall antioxidant properties of these fruit wines were studied. Phenolic compounds were separated by reverse phase (RP) HPLC techniques, and their content was determined by means of mass spectrometer (MS) with triple quadrupole (TQ) analyser, which recorded specific precursor-product transitions. Antioxidant activity was monitored by the following spectrophotometric methods: DPPH, FRAP and Folin-Ciocalteu assay, respectively. Four types of berries (raspberry, blackberry, chokeberry and blueberry), one type of pome (apple) and one type of stone fruit (cherries) were used for the production of fruit wines. Corresponding fruit wines were produced by microvinification with or without adding sugar into the must before fermentation. Increase in alcohol level was responsible for the increased content of phenolic compounds in fruit wine due to improved extraction conditions. Produced fruit wines were preserved by adding SO2 which interferes with the determination of antioxidant activity of phenolic compounds. In this case, the development of a correlation method based on FRAP assay was introduced. Fruit wines are a rich source of substances which show beneficial effects on human health. Depending on the fruit type, different antioxidant compounds were predominant in wine samples.
