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 plea- sant taste (isoamyl acetate – banana, ethyl hexanoate – ripe banana, 2-phenyl- ethyl acetate – powerful fruity rose like) were increased in all samples com- pared 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  - Ова студија је имала за циљ да прикаже профиле ароматичних једињења вина про- изведених од аутохтоних сорти грожђа Крстач (K) и Жижак (Z). Током производње вина од обе сорте коришћени су ензимски препарати (EP): Lallzyme cuvee blanc (CB), Lall- zyme enzymatic preparation β (EB) и различито време контакта покожице (4 и 8 h). Аро- матична једињења су анализирана GC/FID–MS техником. За вина K ЕВ4h (176,33 mg L -1 ) и Z CB4h (177,29 mg L -1 ) уочава се значајно већи садржај укупних ароматичних једињења у поређењу са одговарајућим контролним винима (168,54 and 161,72 mg L -1 ). Про- дужење времена контакта покожице и употреба ЕP углавном повећава садржај 2-фенил- етил- и изоамил-алкохола. Вина обе сорте су показала већи садржај хексанске и октан- ске киселине у односу на контролна вина. Занимљиво је поменути да је у свим узорцима повећан садржај естара који су одговорни за воћну арому вина, која је заслужна за при- јатан укус (изоамил-ацетат – банана, етил-хексаноат – зрела банана, 2-фенилетил-аце- тат – јак воћни мирис руже), у поређењу са контролним винима. Највише оцене, након сензорног оцењивања, добијене су за K EB 8h (18,0 од максималних 20,0) и Z CB 8h (18,2 од максималних 20,0).

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 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  - In this study, we estimated the usage of Cabernet Sauvignon in microvinifications, obtaining wines with increased phenolic compound content. Kinetic extraction of phenolic compounds during alcoholic fermentation was affected by maceration time (3, 5, 7, 14 and 21 days) and the addition and kinetics of enzyme preparations (EP). The highest extraction rates were observed for catechin (EXV EP – EXV en-zyme preparation and CP EP – Color plus enzyme preparation) and p-hydroxybenzoic acid (Car EP - Ca-ractere enzyme preparation). According to extraction time of the analyzed phenolic compounds, maximal values (ellagic acid, ferulic acid, chlorogenic acid, caffeic acid, naringenin, p-hydroxybenzoic acid, p-coumaric acid, protocatechuic acid, trans-resveratrol, syringic acid, vanillin, and vanillic acid) were ob-tained on day 15 of maceration with addition of CP EP, with exceptions of gallic acid, catechin, and my-ricetin. Prolonged maceration times, up to 21 days, showed the most potent DPPH free radical scavenging activity with Car EP and the highest Ferric Reducing Ability of Plasma (FRAP) values with CP EP.

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.

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  - 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  - 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  - Resveratrol is a phytoalexin produced in a number of plant species including grapes. The benefit of resveratrol to health is widely reported. Resveratrol has been found to promote relaxation of non-pregnant and pregnant uterus, but its mechanism of action is unclear. The aims of our study were to investigate the involvement of inwardly rectifying potassium channels (Kir) in inhibitory effects of resveratrol on three models of contractions of non-pregnant rat uterus: the spontaneous rhythmic contractions (SRC), oxytocin-elicited phasic contractions and tonic oxytocin-elicited contractions. Uterine strips were obtained from virgin female Wistar rats in oestrus. Strips were mounted into organ bath for recording isometric tension in Krebs-Ringer solution. Experiments followed a multiple curve design. In order to test the involvement of Kirchannels in a mechanism of action of resveratrol (1-100 μM),BaCl2 (1 mM),a antagonist of inwardly rectifying potassium channels was used. Resveratrol induced a concentration-dependent relaxation of all models of contractions. BaCl2 antagonized the response to resveratrolon SRC and oxytocin-elicited phasic contractions. Relaxation achieved by resveratrolon tonic oxytocin-elicited concentrations was insensitive to BaCl2.The antagonism of resveratrol effects by inwardly rectifying potassium channels antagonist suggests that Kir channels are involved in resveratrol action on phasic contractions of rat uterus. Inhibitory effect of resveratrol on tonic contractions did not include Kir channels.

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.

AB  - Introduction: The consumption of fruit and their product is
very important for balanced nutrition. They are rich source of natural
compounds which show beneficial health effects on human organism.
Fruit wines are rich sources of phenolic compounds which possess an-
tioxidant properties and play role in health protection from oxidative
stress.
Objectives: The aim of this study was to investigate the profile
and in vitro antioxidant properties of fruit wines.
Method / Design: Total polyphenol content was conducted by
using Folin-Ciocalteu method. Anioxidant capacity of samples was
determined by DPPH method, by calculating the percent of inhibition
of DPPH radical. Discoloration was measured on spectrofotometer at
518 nm. Also was used modern FRAP procedure for determination of
antioxidant properties of wine samples. For identification and quantification of some antioxidant compounds HPLC TQ-MS/MS method
was used.
Results: Wines were made from apricot, peach and plum in
winery according to the wine making procedure. From each kind of
fruit were made four different types of wine. All determinations were
conducted in these 12 samples of wine. The total polyphenol content
determined by Folin-Ciocalteu method was in range 358-1389 mg/L
expressed through concentration of gallic acid. The results of DPPH
analyze of samples were in range 35.69-68.50%. The results of antioxidant capacity analyzed by FRAP procedure were in range 21.75-45.15
mmol/Fe2+. Results of HPLC TQ-MS/MS analysis showed that our
samples are sources of compounds such as catechin, epicatechin and
phenolic acids. All those compounds have antioxidant properties.
Conclusions: The obtained results indicate that fruit wines are
sources of antioxidant compounds. Antioxidant properties of fruit
wines depend from which kind of fruit they were made. Natural compounds from fruit wines are particularly important in the prevention
of non-communicable disease caused by oxidative stress.

using Folin-Ciocalteu method. Anioxidant capacity of samples was
determined by DPPH method, by calculating the percent of inhibition
of DPPH radical. Discoloration was measured on spectrofotometer at
518 nm. Also was used modern FRAP procedure for determination of
antioxidant properties of wine samples. For identification and quantification of some antioxidant compounds HPLC TQ-MS/MS method
was used.
Results: Wines were made from apricot, peach and plum in
winery according to the wine making procedure. From each kind of
fruit were made four different types of wine. All determinations were
conducted in these 12 samples of wine. The total polyphenol content
determined by Folin-Ciocalteu method was in range 358-1389 mg/L
expressed through concentration of gallic acid. The results of DPPH
analyze of samples were in range 35.69-68.50%. The results of antioxidant capacity analyzed by FRAP procedure were in range 21.75-45.15
mmol/Fe2+. Results of HPLC TQ-MS/MS analysis showed that our
samples are sources of compounds such as catechin, epicatechin and
phenolic acids. All those compounds have antioxidant properties.
Conclusions: The obtained results indicate that fruit wines are
sources of antioxidant compounds. Antioxidant properties of fruit
wines depend from which kind of fruit they were made. Natural compounds from fruit wines are particularly important in the prevention
of non-communicable disease caused by oxidative stress.",
