AB  - This study examined influence of two different vineyard management practices – biodynamic (BIO) and conventional (CON), applied in a vineyard of a red wine variety Prokupac, (Serbia, 43°18’ 29” N 21°23’15”E), on grape berry quality parameters: soluble solids (SS), pH, total acidity (TA), total phenolic content (TPC), radical-scavenging activity (RSA), and total anthocyanin content (TAC). Both investigated vineyard management approaches were combined with two different winter pruning levels (the bud number per vine was 10 and 20, respectively). Soluble solids content was not influenced by different managements, but very significant differences were found in different bud loads treatments. SS showed significantly higher accumulation in berry in lower bud load treatment, 10 buds (23.8 0 Brix) compared to the 20 bud load (21.7 0 Brix). On contrary, TA showed significant differences between managements, BIO (6.65g L-1) and CON (6.44g L-1). There were differences in TPC between BIO and CON treatments (4.86 and 4.16 mg GAE g-1 respectively). While TPC was significantly higher in the BIO management treatment, bud load treatments were not affected this characteristic. Total anthocyanin content (TAC) was affected only by the management practices and was significantly higher in CON management treatment. Mean value for TAC were 0.10 mg mal-3-glu g-1 (BIO), 0.19 mg mal-3-glu g-1 (CON). TPC, RSA and TA were significantly higher in the biodynamic management treatment compared to the conventional, whereas the pruning level did not affect these attributes. SS content was not influenced by different managements, but different bud load has had. There were not significant differences in pH between applied treatments. These results indicate that the Prokupac has achieved favorable results under the biodynamic management, in terms of quality of wine grapes. In both trailed pruning level treatments, the lower bud number per vine (10 buds) was more favorable. These results clearly justify further research of this topic, with the overall aim to get a full picture of the effect of biodynamic vineyard long management practice on grape quality in Prokupac variety.

AB  - Qualitative and quantitative content of phenolic compounds in monovarietal wines of seven Serbian and two international varieties was determined and compared. The results showed that the variety influences the composition and content for most phenolic components determined in wines. The largest number of phenolic compounds (15) was detected in ‘Prokupac’ wine, while the smallest number (10) was found in ‘Smederevka’ wine. Hidroxybenzoic and hidroxycinnamic acids had the strongest discriminating effect. PCA indicated that phenolic composition depends on both the variety and the vintage, while in some cases their interaction was also manifested. From Serbian variety ‘Prokupac’ wine had the most specific phenolic profile.

AB  - In this research, health risk indices have been used to monitor the transfer of possible contaminants, such as toxic elements, from grapes to humans. The phenolic and elemental profiles of autochthonous and international grape varieties collected in a vineyard located in East Serbia were analyzed. The following results represent a continuation of our previous investigations [1, 2] on phenolic and elemental composition of different grapevine varieties. Here, phenolic acids were determined in skins, seeds, and pulp of grape samples, along with total phenolic content and radical scavenging activity. Total phenolic content and radical scavenging activity were highest in the seeds of autochthonous variety ‘Plovdina’, and in the skins of ‘Smederevka’, where also the highest contents of ferulic, chlorogenic, and caffeic acids were found. Protocatechuic acid was detected only in the seeds of autochthonous varieties. Elemental composition was established for each variety, in the whole berry. ‘Plovdina’ grapes had lower quantities of Al, Ni, and Na in comparison to the other varieties intended for white wine production. Significant correlations obtained among the most abundant elements, pointed to some synergistic interrelations. The potential threat of non-carcinogenic and carcinogenic risk for adults and children who regularly consume the grapes was assessed by calculating daily intake rate, target hazard quotient, hazard index, chronic daily intake, and target cancer risk. Obtained results indicate that all studied grape samples were safe for human consumption.

AB  - The main idea behind this work was to use completely natural and eco-friendly wood waste extract for the treatment of cottage cheese. Heartwood is a rich source of different bioactive metabolites and wood extracts could be applicable in the food and pharmaceutical industries. Following initial phenolic screening [1] and proved antimicrobial activities on eight representative human pathogens, the main focus of this investigation was to test the potential of the extract of wild cherry wood (Prunus avium (L.)) to be used as a preservative to prolong shelf-life of cottage cheese. Different concentrations of cherry tree extract were directly mixed with chees samples and stored under refrigerator conditions (4 ºC). Samples were tested on third, seventh and tenth day. Microbiological analysis included enumeration of total plate count, Enterobacteriaceae, yeast and molds and Staphylococcus spp., using ISO standard methods. Concerning the microbiological quality of cottage cheeses, cherry tree extracts showed strong antimicrobial effect leading to rapid reduction of the microbial groups in treated chees after 3 days, compared with initial count (0 day). Also, yeasts count was significantly reduced in samples after 7 days, while growth of molds was noticed between 7th and 10th day. Results of this investigation are promising in a view of the possibility of the wood extract utilization in preserving perishable foods with short shelf life.

AB  - Many problems on which analytical chemists work originate in other fields, and agriculture is one of them. Analytical chemistry brings a unique perspective to the study of natural products and plant-based food. It is important to highlight the nutritional aspects and phytochemical compounds of fruits that confer human health benefits when they are consumed regularly, preventing development of several diseases. These diverse compounds include dietary fiber, minerals, vitamins, and primary and secondary metabolites that occur naturally in plants.
Various fruits, especially wild and indigenous, are recognized as an excellent source of phytochemicals with health-promoting properties. Our research group mainly focuses on polyphenolic compounds, and so far, we have established profiles of wild Serbian fruits, such as elderberry (Sambucus nigra), hawthorn (Crataegusmonogyna), cornelian cherry (Cornus mas), and blackthorn (Prunus spinosa), and five different Rosa species (R. canina, R. glutinosa, R. rubiginosa, R. multiflora, and R. spinosissima). Results show classification of the fruit samples on the basis of variations in the content of individual flavonoids, phenolic acids and antioxidant capacity and pointed to some unfairly forgotten wild fruits as a great source of bioactive natural compounds. Similarly, we have studied chemical composition of mulberries, strawberries, raspberries, and blackberries. According to the health promoted compounds some genotypes were recommended for clonal propagation and commercialization.
Aside from quality and nutritional value, data gathered from the analysis of carbohydrates, minerals, trace elements and polyphenols could be valuable when questions regarding the differences in the type of the production regime (organic or integrated) should be answered. According to our results, some quantitative variations in individual phenolic compounds and their distribution in fruits and leaves was evident in organic and integrated farming of blueberry and strawberry cultivars. 
To conclude, this work proved wild fruits to be an interesting field in the search for compounds with potential bioactivity. Due to uniqueness in terms of its phytonutrient content, some of investigated fruits were identified as "super-food", and may be considered particularly useful in food supplement production, particularly as a source of natural antioxidants. Furthermore, some of these species could be used in blood sugar regulation and skin protection, or to extend the shelf life of food products and replace synthetic antioxidants, avoiding potential health risks and toxicity. However, additional bioactivity testing is needed, especially bearing in mind the synergistic effect among polyphenols as an important factor determining the functional properties.

AB  - In this research, health risk indices have been used to monitor the transfer of possible contaminants, such as toxic elements, from grapes to humans. The phenolic and elemental profiles of autochthonous and international grape varieties collected in a vineyard located in East Serbia were analyzed. The following results represent a continuation of our previous investigations [1, 2] on phenolic and elemental composition of different grapevine varieties. Here, phenolic acids were determined in skins, seeds, and pulp of grape samples, along with total phenolic content and radical scavenging activity. Total phenolic content and radical scavenging activity were highest in the seeds of autochthonous variety ‘Plovdina’, and in the skins of ‘Smederevka’, where also the highest contents of ferulic, chlorogenic, and caffeic acids were found. Protocatechuic acid was detected only in the seeds of autochthonous varieties. Elemental composition was established for each variety, in the whole berry. ‘Plovdina’ grapes had lower quantities of Al, Ni, and Na in comparison to the other varieties intended for white wine production. Significant correlations obtained among the most abundant elements, pointed to some synergistic interrelations. The potential threat of noncarcinogenic and carcinogenic risk for adults and children who regularly consume the grapes was assessed by calculating daily intake rate, target hazard quotient, hazard index, chronic daily intake, and target cancer risk. Obtained results indicate that all studied grape samples were safe for human consumption.

AB  - The first reported occurrence of Vitis vinifera in Balkan dates in the Neolithic period in the form of wild grape. Early traces of viticulture and winemaking in the territory of Serbia are vessels from the Iron Age (~ 400 BC) and the Bronze Age (~ 200 BC). Over the last few decades, interest in autochthonous varieties in Serbia is constantly increasing, especially for growing native varieties, such as Prokupac, Smederevka, Tamjanika and Bagrina. Prokupac is the most important Serbian autochthonous red wine variety (the first written records about growing Prokupac in Serbia date from 12th century), well adapted to the ecological conditions of its birthplace with corresponding phonological features. When compared with germplasm representing the classical ecogeographic grouping of grapevine cultivars, Prokupac is clustered within the Convar pontica subconvar balcanica taxon, supporting his indigenous origin. The main objective of this work is to present characterization of the Prokupac variety by means of ampelographic and molecular analysis, as well as grape and wine chemical characteristics. Long-term cultivation in diverse ecological conditions has caused the Prokupac to become a mixture of clones (genotypes). Therefore in order to preserve and improve autochthonous grapevine varieties in Serbia, work on variety clonal selection was initiated and till now, 12 clones of Prokupac were already identified and recognized. The most important features of these clones will be also presented.
