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.
AB  - Cilj ovog istraživanja bio je da se ispita uticaj različitih klonova autohtone srpske sorte Prokupac kao i postupak vinifikacije na sadržaj transi cisrezveratrola i sadržaj ukupnih polifenola (SUP) u vinima. 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). Najviši SUP je bio u vinima proizvedenim primenom enzimskog preparata glikozidaza OE i kvasca 299. Dobijeni rezultati ukazuju da je izborom odgovarajućeg klona, dužine maceracije, primene odgovarajućeg kvasca i enzimskog preparata moguće povećati sadržaj rezveratrola i drugih fenolnih jedinjenja u vinu.

AB  - This paper is based on determining the level of the antioxidant activity of beer, to which sensory acceptable amounts of selected extracts of medicinal plants were added, with the aim of obtaining a beer with increased functional and new sensory features. For purposes of this study a commercial lager beer type Pils and extracts of herbal drugs: Melissae folium, Thymi herba, Juniperi fructus, Urticae radix and Lupuli strobuli, were used. Total phenols were analyzed by the method of Folin-Ciocalteu, and the antioxidant activity of samples was evaluated using FRAP and DPPH tests. Sensory evaluation of beer was conducted on 80 subjects, using a nine-level hedonic scale. The results showed that the content of total phenols was the highest in the beer which thyme, juniper and lemon balm were added to (384.22, 365.38 and 363.08 mg GAE/L, respectively), representing an increase of 37.09, 30.36 and 29.55%, respectively, compared to the commercial lager beer. Values of antioxidant activity were correlated with the content of total phenols. The extract of lemon balm blended in the best manner with the baseline, commercial lager beer in terms of sensory acceptability. The new beer, enriched with lemon balm, had a pleasant, appealing and harmonious flavor and aroma.

AB  - Wines and beers are a rich source of different compounds that show beneficial effects to the human body and their consummation in reasonable amounts can improve health. Among them, the most important are phenolic compounds (nonflavonoids, flavonoids, tannins), which possess antioxidative properties and could be responsible for prevention of many diseases. The aim of this study was to determine the content of total flavonoids, monomeric and total anthocyanins in samples of wines from different grape varieties produced in Serbia and beers produced with the addition of grapes. Analysis was performed on 14 samples including 5 red wines made from grape varieties from Serbia, one regular beer, and 7 beer samples enriched with different grape varieties and percentage of grape. Monomeric and total anthocyanins were determined spectrofotometrically by the pH differential method, while the total flavonoid content was determined according to the colorimetric Folin-Ciocalteu method after precipitation with formaldehyde. Anthocyanins were quantified in all analyzed samples, except in regular beer. The highest values were found in wines made from variety Prokupac (270,80 mg/l and 388,79 mg/l malvidine-3-glucoside equivalents, for monomeric and total anthocyanins, respectively). Flavonoids were present in all analyzed samples. Wine samples showed higher content of flavonoids (the highest in Merlot wine) than beer and drinks from beer and grapes. The content of anthocyanins and flavonoids in beer samples enriched with grapes increased with the increase of added amount of grapes. Obtained results showed that relatively high concentrations of flavonoids and anthocyanins are present in wines produced in Serbia. Also, addition of grape in beer increased content of these beneficial phenolic compounds, which can be important factor for quality of a new developed product.
