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  - Since fishery products represent an important and globally growing food resource, there is also an increased incidence rate of intentional mislabelling of fish products and restaurant frauds globally. In the present study, Raman spectroscopy, as a fast and non-invasive technique, was applied using a laser at a wavelength of 532 nm for the classification of deep frozen fish fillets. Without any preparation, muscle tissue of 12 fish types was analysed with a Raman device, and according to a hierarchical cluster analysis of their spectra, three groups were identified: (1) the carotenoid group, fish from salmonid family; (2) the freshwater group, fish that was reared in fresh or brackish water; and (3) the saltwater group, fish reared in saltwater. Thus, it is demonstrated that Raman spectroscopy can be used as a direct, non-expensive and fast screening method before proceeding with standard methods for the identification of fish fillets.

AB  - Quinoa is an Andean seed crop of many potential uses. In 2009 a field trial was carried out to explore the potential for quinoa growing in climatic conditions of South Eastern Europe. Even under rainfed conditions, without fertilization, a seed yield as high as 1.721 t ha(-1) was obtained. Seed quality was remarkably good, with protein content ranging from 15.16 to 17.41 % on a dry weight basis, depending on whether seeds were processed. Amino acid and mineral composition revealed the potential of quinoa seeds as a valuable ingredient in the preparation of highly nutritious foods. Quinoa seeds had higher contents of most essential amino acids, especially lysine, than wheat flour. Dehulled quinoa seeds, devoid of saponins, were included into wheat bread formulations, with up to 20%, which resulted in a positive effect on the rheological characteristics of dough. Furthermore, protein content in bread was increased by around 2%. Sensory characteristics of breads were excellent also at the 20% supplementation level. The study of bread supplemented with quinoa seeds could enable the development of a range of new baking products with enhanced nutritional value.

AB  - Partial root-zone drying (PRD) is a new water-saving irrigation strategy which requires that the roots are simultaneously exposed to both dry and wet soil zones. This technique is now undergoing extensive trials with a range of agricultural crops. These results show significant benefit in increasing water-use efficiency. The field potato (Solanum tuberosum L cv Liseta) experiments were conducted during 2007 and 2008. Subsurface drip irrigation was used. In 2007 season PRO plants received 70% of full irrigation (FI). To further enhance water saving during the last 3 weeks of the irrigation period, PRO using 70% of FI was replaced with PRD using 50% of FI in 2008. By five harvests during the season N content, fresh and dry matter (DM) of leaves, stems and tubers were followed. At final harvest the effects of PRD and FI irrigation on total and marketable yield and yield quality were investigated. Also, the irrigation water-use efficiency (IWUE) was calculated. As compared to FI, PRO treatment saved 33% (2007) and 42% (2008) of irrigation water while maintaining similar yield. This resulted in 38% and 61% increase in IWUE for the 2007 and 2008 seasons, respectively. In both years the PRO treatments resulted in the increase of N, starch content and antioxidant activity in potato tubers. The latter novel findings on the effect of PRD irrigation on tubers quality might be favorable for the health-promoting potato value.

AB  - Drip irrigation systems and irrigation strategies like deficit irrigation (DI) and partial root drying (PRO) are potential water saving irrigation systems and strategies. This paper analyses the Serbian farmer's economic incentive to use these water saving systems and strategies instead of the present sprinkler irrigation. The analysis is a partial budgeting analysis, based on irrigation application efficiency from the literature, standard figures for power requirements, pumping efficiency and friction losses for various sources of water and pressure requirements, yields and water use from recent Serbian field experiments, as well as prices and cost structures for potatoes collected in the Belgrade region. The analysis shows that changing the present system and strategy can save a significant amount of water (almost 50%). At the same time, however, irrigation costs are also significantly increased (more than doubled), and the total production costs are increased by 10% (deficit drip irrigation) and 23% (PRD). Increased taxes on water, investment subsidies, increased energy prices, and an increased yield or yield quality may provide incentives for farmers to change to new systems and strategies. The analysis indicates that a 0.80 to 1.97(sic) m(-3) water tax is needed to make deficit drip irrigation and PRD profitable. The socioeconomic cost of providing water for irrigation and the alternative value of saved water are probably not that high. Thus, water taxation may not be a socioeconomic efficient means to improve the irrigation water productivity of Serbian potato production. Drip irrigation and PRD may, however, also increase the yield quality, and a 10-23% quality premium (price increase) is needed to make deficit drip irrigation and PRD profitable.
