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  - 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  - U ovom radu određivan je sadržaj polifenola i antioksidativna aktivnost vodeno-etanolnog ekstrakta morača, sa ciljem ispitivanja mogućnosti njegove primene kao potencijalnog funkcionalnog aditiva. Ukupni fenoli su analizirani metodom po Folin-Ciocalteu, dok je ukupan sadržaj flavonoida određen kolorimetrijskom metodom primenom aluminijum hlorida. Razdvajanje i kvantifikacija fenolnih jedinjenja postignuti su upotrebom LC-MS/MS metode u režimu koji omogućava istovremeno praćenje više jonskih prelaza. Antioksidativni kapacitet je određivan primenom testova FRAP i DPPH. U testiranom ekstraktu dobijene su visoke vrednosti za ukupne fenole i flavonoide, a dobijena je i visoka vrednost antioksidativne aktivnosti, koja je iznosila 9023.33 ± 38,19 mmol Fe(II)/l i 3,73 ± 0,04 mmol TE/l, računato primenom testa FRAP odnosno testa DPPH. Među fenolnim jedinjenjima, phidroksibenzoeva i hlorogena kiselina su pronađene kao dominantne. Dobijeni rezultati ukazuju na to da se ekstrakt morača može primenjivati u prehrambenoj industriji kao potencijalni prirodni antioksidans.

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  - 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 analyzed 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 γ-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.
