AB  - Human noroviruses (HuNoV) are the dominant cause of viral gastroenteritis in all age groups worldwide. In this study, we investigated the effects of pomegranate peel extract (PPE) on the reduction of HuNoV in different food models, on surfaces of fresh produce (green onion and cherry tomato), in low-fat milk, and simulated gastrointestinal fluids. The antiviral efficacy of PPE against HuNoV was evaluated by quantifying the number of residual virus genomes using a quantitative reverse transcription PCR (qRT-PCR) assay. Pomegranate peel, considered as a waste product of industrial processing, is known for beneficial health effects and broad antimicrobial activity due to the high content of phenolic compounds and tannins. PPE showed significant antiviral properties against HuNoV both in phosphate-buffered saline (PBS) and simulated gastric fluid. The reduction of HuNoV by pomegranate juice was lower than with PPE, which could be attributed to the lower content of antimicrobial compounds. A pretreatment of cherry tomato and green onion surfaces with PPE significantly reduced the amount of HuNoV particles that adhered to those surfaces during subsequent virus suspension treatment. A detrimental effect of PPE on HuNoV structure was confirmed by transmission electron microscopy. Our results indicate that PPE is a natural antiviral agent effective against food-borne noroviruses.

AB  - Aim: Microencapsulation of chokeberry extracts was performed in order to improve functionality, stability, and bioavailability of extracted polyphenols. Methods: Chokeberry fruits and juice by-product (waste) extracts were spray-dried by using two carriers, maltodextrin and skimmed milk. Morphological and physicochemical characteristics of the obtained powders were analysed. In vitro simulated digestion model was used as an indicator of polyphenolics bioavailability. Results: The moisture content varied between 3.39 and 4.61%, zeta potential had negative values (35-39 mV), maltodetrin powders were smaller (4.27-5.12 mu m) compared to skimmed ones (8.50-11.01 mu m). All microparticles exhibited high encapsulation efficiency of total polyphenols and anthocyanins (73-97% and 63-96%, respectively). For both extract types, maltodextrin powders released higher phenolics content compared to skimmed milk. During in vitro digestion, maltodextrin exhibited a higher protective effect on both active compounds. Conclusion: Taking into account the obtained results, chokeberry polyphenols stability might be improved using spray drying technique, and maltodextrin showed better properties.

AB  - Sandy everlasting [Helichrysum arenarium (L.) Moench] is herbaceous perennial plant belonging to Asteraceae family and it is native to Europe, Central Asia, and China. It belongs to the section HELICHRYSUM (Asteraceae family, genus Helichrysum) along with H. plicatum DC. Prodr., which very similar phenolic profile and H. italicum (Roth), which is widely used for essential oil extraction. Its flowers have a long tradition in European ethnomedicine as a cholagogue, choleretic, hepatoprotective, and detoxifying herbal drug. The flowers are rich in phenolic compounds including flavonoids, chalcones, phenolic acids, coumarins, and pyrones. Apart frompolyphenols, other compounds such as sterols, lignans, and glycosides of aromatic compounds have been also isolated from H. arenarium. The majority of authors confirm that the most important group of compounds responsible for biological activities is flavonoids. Moreover, significant activities of naringenin, one of the main flavonoids of H. arenarium, were reported. On the other hand, there are no clinical data about testing the extracts or preparations based on H. arenarium. Although H. arenarium is well known in phytotherapy for its potential in the treatment of gallbladder disease and are classified as endangered species in a number of European countries, very few data about its cultivation are available in the literature.

AB  - Due to its high content of phenolics, black chokeberry has been proposed as a health-promoting material, especially use of chokeberry extract as a food or pharmaceuticals. Chokeberry extract was spray-dried using gum Arabic as a carrier. The optimal conditions for the efficient microencapsulation of chokeberry extract using spray-drying technique have been investigated. The aim of our study was to obtain microparticles with the best potential to improve functionality and stability of extracted chokeberry polyphenols, and to investigate the possibility of microbeads to protect active compounds during simulated digestion process. Morphological characteristics of microbeads were analyzed using FTIR and SEM techniques. Zeta potential, particle size and moisture content were determined. Released total phenolics and total anthocyanins content as well as concentration of individual anthocyanins were quantified before and after digestion process. Microparticles exhibited high encapsulation efficiency up to 87%, and high content of released polyphenols was achieved. After in vitro simulated digestion phenolic compounds decreased by 11-24%, exhibited higher protective effect of gum Arabic. Our results showed that chokeberry microparticles obtained by spray drying method could be useful supplements or functional food. .

AB  - Arnica (Arnica montana L) is a perennial mountain plant whose flower heads are mainly used for topical treatment of bruises and sprains in phytopharmaceutical preparations such as ointments, creams and gels. In this study, different models of arnica cultivation have been tested in three-year field trial arranged in 2 x 3 x 2 factorial design. Planting date (spring and autumn), fertilizater type (manure, NPK and control) and mode of reproduction (generative and clonal) were induced factors on the trial. The variation of the rosette diameter, flowering stem count and height, flower heads count and diameter, together with flower heads yield and chemical properties were investigated as morphological parameters. Spring planting of clonally propagated plants was showed to be the least successful model due to the low percent of rooted plants and weak shoot development. Other models yielded from 59.8 to 143.6 kg ha(-1) and 116.3 to 258.7 kg ha(-1) flower heads (dw) in the second and third year, respectively. Total sesquiterpene lactones content in flower heads of all tested variants was above the minimum of pharmacopeia quality regulation and ranged from 4.6 to 13.9 mg g(-1) depending on factor levels, while the amounts of two dominant flavonoid compounds quercetin-3-O-glucoside and kaempferol-3-O-glucoside ranged from 7.8 to 13.9 mg g(-1) and from 2.1 to 4.7 mg g(-1), respectively. All induced factors in the field trial significantly influenced variation in both morphological and chemical parameters, where fertilized variants from autumn planting have shown to be superior in flower heads yield with satisfying levels of the secondary metabolites content. Factorial analysis distinguished that half of morphological parameters positively correlated with flower heads yield. First three ranks of sequential classification of cultivation models with desirable properties were captured by variants planted in autumn, while the last rated variants were those from clonal propagation planted in spring. This attempt of arnica domestication in agroecological conditions of western Serbia has proven to be successful in ensuring high quality raw material, providing at the same time answers to the questions that have not been reviewed so far.

AB  - Changes of environmental factors, created under influence of various shading nets, could significantly affect some pomological and organoleptic characteristics of plants grown in such conditions as well as biosynthesis of phenolic compounds. Five black currant cultivars Ben Sarek, Ben Nevis, Ben Lomond, Ometa, and Cacanska crna were cultivated either in the shade of green polyethylene nets or exposed to direct sunlight during two experimental seasons. All berries in the control treatment (without shading nets) contained higher amounts of total phenolics in both experimental seasons: 474-520 mg GAE/100 g in 2010, and in 2011 it ranged from 401 to 501 mg GAE/100 g. Similar but less expressed trend was noticed regarding anthocyanins content. Growing in shade generally led to a lower content of flavonoid, phenolic acid and anthocyanin compounds, determined by HPLC/MS. Despite the reduction of phenolic compounds content, all tested varieties expressed significant radical scavenging activity against DPPH radical, and differences in antiradical activity were statistically significant only between varieties.

AB  - Thirteen black currant varieties (Ribes nigrum L.) cultured in Serbia were characterized for their pomological properties and chemical composition (total phenolics, total anthocyanins, anthocyanin aglycones, sugars, and vitamin C). The average amount of vitamin C varied from 122.4 to 193.2 mg/100 g fresh weight (FW), while concentration of invert sugars ranged from 6.3% to 11.1%. The highest amounts of total phenolics and anthocyanins were detected in variety Ometa (278.9 mg of gallic acid equivalents per 100 g of FW [mg GAE/100 g FW] and 135.4 mg/100 g, respectively). Quantitative analyses of anthocyanin aglycones in berries were performed using high-performance liquid chromatography, and delphinidin was found to be dominant compound in 11 varieties. Total phenolics and anthocyanins contents decreased during the processing of berry fruits to juices, and the reduction of anthocyanins was more pronounced, 12%-80%. The radical scavenging activity of black currant juices was investigated by 1,1-diphenyl-2-picrylhydrazyl, and the IC50 value ranged from 1.9 to 4.0 mg/mL. Our results also showed that freezing as a way of preservation and storage could save important phytochemicals and health benefits of berries and berry juices. The amount of total phenolics in berries increased during 1 year of storage by 46.09%-171.76% and in juices by even 107.58%, while the amount of total anthocyanins in berries and juices decrease by 5.63%-52.76% and 13.04%-36.82%, respectively.

AB  - This paper presents the results of research conducted on five cultivars of white currant ('Primus', 'White Champagne', 'Witte aus Juteborg', 'Witte Parel' and 'Viktoria'), in the 2007-2009. In addition to biological and production characteristics, indicators of dietary-therapeutic values of the observed cultivars fruits were examined too. The results showed that 'Primus' and 'Victoria' cultivars have significantly higher production value than other cultivars, which recommends them for further expansion in similar agro-ecological conditions. After one year of storage at temperature of -18 degrees C, content of total phenolics in the fruits was examined, while the antiradical activity was tested in the corresponding juices. Cultivar 'Primus' significantly differs in both its total phenolic content and antiradical activity.

AB  - Eleven red currant varieties (Ribes rubrum L.) cultured in Serbia were evaluated for some of their biochemical properties such as total phenolics, anthocyanins, ascorbic acid, invert sugar, soluble solid content, and acidity. The average amount of ascorbic acid varied from 50.5-71.6 mg/100 g FW, while concentration of invert sugars ranged from 6.0%-9.0%. The highest amounts of total phenolics and anthocyanins were detected in variety Redpoll (153.4 mg GAE/100 g FW and 19.3 mg/100 g, respectively). Red currants were processed to juice, and the phenolic and anthocyanin contents changed as a result of processing. Berries and juices were long-term stored at -18 A degrees C and changes in phytochemicals were monitored. In berries, storage caused the decrease of ascorbic acid content up to 49%, and a general reduction of total phenolics was also noticed. In juices, total phenolics content increased after one year of storage. In both berries and juices total anthocyanins increased during storage by up to 85% and 50%, respectively. This study demonstrates that certain varieties, namely Redpoll, Jonkheer and London Market are good source of phytochemicals, retaining the nutritional value during processing and storage.

AB  - Chemical composition and the effects of domestic processing and storage were studied in organically cultivated or wild growing berries, harvested in certificated area in Serbia. The total phenolics content in fresh berries ranged from 380 to 1660 mg GAE/100 g. The phenolic content decreased during the processing to jams, and storage in almost all samples, except in black currant. Among fresh berries, the highest amount of total anthocyanins was found in bilberry (0.61 +/- 0.03 %). Processing and storage caused decrease in anthocyanin content. The most ubiquitous anthocyanin aglycone was found to be cyanidin. Ellagic acid was detected in fresh and frozen black raspberries and related jams, and its content increases during thermal processing to jam. Among fresh berries, bilberry showed the strongest DPPH radical scavenging activity with an IC(50) value of 0.82 mg/ml. However, frozen as well as processed berries in our study still showed comparable high values of radical scavenging activity. After 9 months of storage all investigated jams were microbiologicaly correct. Regardless of the losses in the amount of total phenolics, total anthocyanins and radical scavenging activity, frozen berries and related jams are still excellent sources of nutritional substances with antioxidant potential.
