AB  - Ova doktorska disertacija fokusirana je na hemijsku i biološku karakterizaciju odabranih uzoraka crvenih vina. Akcenat je stavljen na hemijsku karakterizaciju klonskih sortnih vina vranac i merlo, kao i na procenu antioksidativne aktivnosti vina sorte merlo u ćelijama kvasca. Pored uobičajenih spektrofotometrijskih metoda, primenjene su elektrohemijske metode (ciklična voltametrija i klasična polarografija), kao i EPR spektroskopija. Tečnom hromatografijom sa ultraljubičastim detektorom sa nizom dioda (PDA) i masenim detektorom sa tri analizatora – trostruki kvadrupol (QQQ) određen je fenolni profil analiziranih uzoraka vina. Njihov elementalni profil je okarakterisan pomoću induktivno spregnute plazme kuplovane sa optičkom emsionom spektroskopijom (ICP-OES) ili masenom spektrometrijom (ICP-MS). Antiradikalske aktivnosti ispitane su i na fiziološki relevantnim slobodnim radikalima (hidroksil i superoksid anjon). Osim toga, utvrđena je i ukupna antioksidativnost, kao i druge biološke aktivnosti (citotoksična i antibakterijska aktivnost) odgovarajućih uzoraka vina. Eksperiment na bazi vinskog kvasca je obuhvatio određivanje koncentracije proteina, ukupnih grupa –SH, kao i enzimskih aktivnosti (glutation peroksidaza, glutation reduktaza i katalaza). Eksperimentalno dobijeni podaci za klonska sortna vina merlo ukazuju na poseban doprinos glutation peroksidaze preživljavanju ćelija kvasca u uslovima oksidativnog stresa. Konačno, primenom veštačke neuronske mreže (ANN) razvijena je brza i precizna metoda za predviđanje uticaja malih promena u vinskom fenolnom profilu na aktivnosti istaknutih enzima antioksidativne zaštite. Svi protokoli u okviru ove disertacije mogu se primeniti kako na crvena, tako i na bela i roze vina.
AB  - This doctoral dissertation focuses on the chemical and biological characterisation of selected red wine samples. Emphasis is placed on the chemical characterisation of clonal wines of Vranac and Merlot varieties, as well as on the evaluation of the antioxidant activity of Merlot wines in yeast cells. In addition to the usual spectrophotometric methods, electrochemical methods (cyclic voltammetry and classical polarography) as well as EPR spectroscopy were also applied. Phenolic profile of the analysed wine samples was determined using liquid chromatography with a multi-diode (PDA) ultraviolet detector and a triple quadrupole (QQQ) mass detector. The elemental profile is characterised by inductively coupled plasma coupled with optical emission spectroscopy (ICP-OES) or mass spectrometry (ICP-MS). Antiradical activities were also screened for physiologically relevant free radicals (hydroxyl and superoxide anion). In addition, total antioxidant activity as well as other biological activities (cytotoxic and antibacterial activity) of the respective wine samples were determined. The wine yeast experiment involved determining the concentration of proteins, total groups –SH, as well as enzymatic activities (glutathione peroxidase, glutathione reductase and catalase). The experimentally obtained data for clonal Merlot wine varieties indicate a particular contribution of glutathione peroxidase to the survival of yeast cells under oxidative stress conditions. Finally, using an artificial neural network (ANN), a rapid and accurate method was developed to predict the effect of small changes in the wine phenolic profile on the activities of prominent antioxidant enzymes. All protocols within this dissertation can be applied on white and rose wines as well.

AB  - The overall aim of this paper was to compare the multielement composition and antioxidant capacity of two Montenegrin Merlot wines obtained from specific vine clones (VCR1 and VCR 101) along with commercial Merlot wine throughout the consecutive vintages in 2010 and 2011. Elemental composition was analysed using inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). Additionally, antioxidant capacity was assessed by cyclic voltammetry. VCR 1 wine from 2011 stood out for its elemental composition. On the other hand, antioxidant capacity of VCR 101 wines was the highest one for the both vintages. According to the experimental data obtained, all three wines are good source of essential elements and products with a significant antioxidant activity and specific geographical origin.

AB  - This study aimed to describe quality and potential health benefits of three Vranac wines obtained from new grape clones (CI, CII and CIII) recently developed and recognised. In this aim, their phenolic profiles, anti-2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical activities along with metal compositions were analyzed. Compared with the commercial one, CII and CIII Vranac wines were found to contain both higher contents of total phenolics, flavonoids and monomeric anthocyanins as well as anti-DPPH radical activities. The most abundant phenolics were gallic acid (8.88-16.36 mg/L), catechin (12.42-24.35 mg/L) and epicatechin (4.30-7.79 mg/L). Finally, the metal content of all the analyzed samples was within the toxicological safety limits. Taken all together, Montenegrin Vranac wines represent a rich source of both phenolics and minerals exhibiting promising antioxidant potential. CII and CIII wines can be considered for commercialising due to their high amounts of gallic acid, catechin and epicatechin, significant K/Na ratios and favourable contents of essential metals making them products with health added values.

AB  - Screens of antioxidant activity (AA) of various natural products have been a focus of the research community worldwide. This work aimed to differentiate selected samples of Merlot wines originated from Montenegro, with regard to phenolic profile and antioxidant capacity studied by survival rate, total sulfhydryl groups and activities of glutathione peroxidase (GPx), glutathione reductase and catalase in H2O2-stressed Saccharomyces cerevisiae cells. In this study, DPPH assay was also performed. Higher total phenolic content leads to an enhanced AA under both conditions. The same trend was observed for catechin and gallic acid, the most abundant phenolics in the examined wine samples. Finally, the findings of an Artificial Neural Network (ANN) model were in a good agreement (r(2) = 0.978) with the experimental data. All tested samples exhibited a protective effect in H2O2-stressed yeast cells. Pre-treatment with examined wines increased survival in H2O2-stressed cells and shifted antioxidative defense towards GPx-mediated defense. Finally, sensitivity analysis of obtained ANN model highlights the complexity of the impact that variations in the concentrations of specific phenolic components have on the antioxidant defense system.

This work aimed to differentiate selected samples of Merlot wines originated from Montenegro, with regard to phenolic profile and antioxidant capacity studied by survival rate, total sulfhydryl groups and activities of glutathione peroxidase (GPx), glutathione reductase and catalase in H2O2-stressed Saccharomyces cerevisiae cells. In this study, DPPH assay was also performed. Higher total phenolic content leads to an enhanced AA under both conditions. The same trend was observed for catechin and gallic acid, the most abundant phenolics in the examined wine samples. Finally, the findings of an Artificial Neural Network (ANN) model were in a good agreement (r(2) = 0.978) with the experimental data. All tested samples exhibited a protective effect in H2O2-stressed yeast cells. Pre-treatment with examined wines increased survival in H2O2-stressed cells and shifted antioxidative defense towards GPx-mediated defense. Finally, sensitivity analysis of obtained ANN model highlights the complexity of the impact that variations in the concentrations of specific phenolic components have on the antioxidant defense system.",

AB  - In this study, the polyphenol profile and antioxidant activity of the hydro-ethanolic extract of the fennel fruit were examined in order to investigate the possibility of its application as a potential functional food additive. Total phenols were analyzed by the method of Folin-Ciocalteu, while total flavonoids were determined by the aluminum chloride colorimetric method. The separation and quantification of phenolic compounds were performed by LC-MS/MS analysis, using a multiple reaction monitoring (MRM) mode. The antioxidant capacity was determined by FRAP and DPPH assays. The high values of total phenolics and flavonoids were found, as well as high antioxidant activity which amounted to 9023.33 ± 38.19 µmol Fe(II)/l and 3.73 ± 0.04 mmol TE/l, tested by FRAP and DPPH assays, respectively. Among the identified phenolic compounds, p-hydroxybenzoic and chlorogenic acids were detected as predominant. The obtained results indicated that the hydro-ethanolic extract of the fennel fruit can be used in food industry as a potential natural antioxidant.

AB  - The overall aim was to compare the quality of two Montenegrin Merlot wines obtained from new vine clones (VCR1 and VCR 101) along with commercial Merlot wine throughout the consecutive vintages in 2010 and 2011, due to preliminary screening of the potential of novel Merlot vine clones for the wine industry. The content of phenolic compounds was determined by liquid chromatography tandem mass spectrometry (LC-MS/MS). Elemental composition was analysed using inductively coupled plasma optical emission spectrometery (ICP-OES) and inductively coupled plasma mass spectrometery (ICP-MS)]. Additionaly, antioxidant capacity was assessed by cyclic voltammetry. Compared with the commercial one, both wine clones contained higher percent of major phenolic compounds (namely, gallic acid and catechin) with top values recorded for VCR1 both in 2010 (30.46 +/- 0.42 mg/1) and 2011 (28.12 +/- 0.29 mg/1). The same wines were enriched with epicatechin, resveratrol, myricetin and quercetin. Furthermore, VCR 1 wine from 2011 stood out for its elemental composition. On the other hand, antioxidant capacity of VCR 101 wines was the highest one for the both vintages. According to the experimental data obtained, both new Montenegrin Merlot wines represent good candidates for the commercialised wines with an indication of geographical origin.

AB  - Samples of the selected red wine varieties grown in Montenegro (Merlot, Cabernet Sauvignon and Vranac; vintages 2010-2012) were compared according to total phenolic content, anti-DPPH radical activity, phenolic profile and elemental composition. All the samples showed profound anti-DPPH radical activity, due to high content of total phenolic compounds (R=0.92). The most abundant phenolics were catechin and gallic acid with the highest values recorded for Merlot 2012 (43.22 and 28.65mg/L, respectively). In addition to this, the content of essential elements including the potentially toxic ones was within healthy (safe) level for all the samples analysed. This study has actually pointed out Merlot wine variety as the best quality one, though all three varieties may be used as safe and health-promoting nutritional products. [GRAPHICS] .

AB  - Background: Protein oxidation can occur as a consequence of lipid peroxidation during food processing. The aim of this work was to explore the effect of malondialdehyde (MDA) modification of ovalbumin (OVA) on its interaction with T84 intestinal cells. Methods: Molecular dynamics simulation was employed for the prediction of MDA modification in the OVA, while introduced structural changes were evaluated by measurement of carbonyl group content, fluorescence spectra, MS/MS analysis, and IgE reactivity. Effects of MDA modified OVA on T84 epithelial cells were analyzed by gene expression for pro-inflammatory cytokines and protein secretion. Results: Out of 9 predicted, five modified Lys residues were confirmed by MS/MS analysis: (51)TQINKVVR(58), (85)DILNQITKPNDVYSFSLASR(104), (111)YPILPEYLQCVKELYR(126), (187)AFKDEDTQAMPFR(99), (KIKVYLPR284)-K-277, and (IKVYLPR284)-I-278. The introduced MDA modifications influenced profile of IgE reactivity to OVA. Treatment of T84 epithelial cells with OVA and OVA modified with 1 mM MDA, induced up-regulation of pro-inflammatory cytokines (IL-1 beta,IL-25, IL-33, TSLP and TNF alpha), while OVA modification with 10 mM MDA induced down regulation of the cytokine expression profile, except for IL-1 beta. OVA and OVA modified with 1 mM MDA induced secretion of epithelial cells specific cytokine IL-33. Conclusions: This finding indicated that OVA and its MDA modified form have the potential to trigger the innate immunity by inducing up-regulation and secretion of pro-allergenic IL-33 in T84 intestinal epithelial cells. General significance: Interactions of ovalbumin and its MDA modified form with intestinal epithelial cells can induce a specific immunological priming necessary for the downstream activation of innate immunity.

AB  - ackground: Protein oxidation can occur as a consequence of lipid peroxidation during food processing. The aim of this work was to explore the effect of malondialdehyde (MDA) modification of ovalbumin (OVA) on its interaction with T84 intestinal cells. Methods: Molecular dynamics simulation was employed for the prediction of MDA modification in the OVA, while introduced structural changes were evaluated by measurement of carbonyl group content, fluorescence spectra, MS/MS analysis, and IgE reactivity. Effects of MDA modified OVA on T84 epithelial cells were analyzed by gene expression for pro-inflammatory cytokines and protein secretion. Results: Out of 9 predicted, five modified Lys residues were confirmed by MS/MS analysis: (51)TQINKVVR(58), (85)DILNQITKPNDVYSFSLASR(104), (111)YPILPEYLQCVKELYR(126), (187)AFKDEDTQAMPFR(99), (KIKVYLPR284)-K-277, and (IKVYLPR284)-I-278. The introduced MDA modifications influenced profile of IgE reactivity to OVA. Treatment of T84 epithelial cells with OVA and OVA modified with 1 mM MDA, induced up-regulation of pro-inflammatory cytokines (IL-1 beta,IL-25, IL-33, TSLP and TNF alpha), while OVA modification with 10 mM MDA induced down regulation of the cytokine expression profile, except for IL-1 beta. OVA and OVA modified with 1 mM MDA induced secretion of epithelial cells specific cytokine IL-33. Conclusions: This finding indicated that OVA and its MDA modified form have the potential to trigger the innate immunity by inducing up-regulation and secretion of pro-allergenic IL-33 in T84 intestinal epithelial cells. General significance: Interactions of ovalbumin and its MDA modified form with intestinal epithelial cells can induce a specific immunological priming necessary for the downstream activation of innate immunity.

AB  - Medlar is the fruit of Mespilus germanica L. in the family of Rosaceae. The fruit can be eaten only if "bletted" (softened by frost or longer storage). The effect of the maturation stages on the volatile compounds of the medlar fruit was investigated during two different stages. Volatile flavour substances were isolated from the minced pulp of unripe and full ripe medlar fruits by simultaneous steam distillation extraction (SDE) with methylene chloride as the extracting solvent. The concentrate was analysed by GC-FID-MS. Hexanoic and hexadecanoic acids were the predominant acids, hexanal and (E)-2-hexenal were the predominant aldehydes, (Z)-3-hexenol and hexanol were the predominant alcohols, with p-cymene, terpinen-4-ol, and gamma-terpinene (the terpenes responsible for the characteristic medlar flavour) being also present. The C6 aliphatic compounds, such as hexanal and (E)-2-hexenal, were observed as the major volatile constituents in the green stage. In contrast, hexanol and (Z)-3-hexenol were the main volatiles in ripe fruits.
AB  - Mušmula (Mespilus germanica L) je voće iz porodice ruža (Rosaceae). Zeleni plodovi mušmule nisu jestivi već treba da ugnile (omekšaju usled mraza ili tokom čuvanja) pre nego što se koriste u ishrani. Efekat procesa sazrevanja na isparljive komponente ploda mušmule ispitivan je u dve različite faze njegove zrelosti. Isparljiva jedinjenja su izolovana iz izmrvljene pulpe nezrelih i zrelih plodova mušmule pomoću simultane destilacije vodenom parom i ekstrakcije metilen-hloridom. Koncentrovani uzorak je analiziran kombinacijom metoda GC-FID-MS. Heksanska i palmitinska kiselina su najzastupljenije kiseline, heksanal i (E)-2-heksenal su najzastupljeniji aldehidi, (Z)-3-heksenol i heksanol su najzastupljeniji alkoholi i p-cimen, terpinen-4-ol i γ-terpinen, terpeni odgovorni za karakterističnu aromu ploda mušmule, takođe su prisutni. C6 alifatična jedinjenja, kao što su heksanal i (E)-2-heksenal su nađeni kao glavne isparljive komponente zelenih mušmula.
