Atmospheric cold plasma technology for meat industry: A bibliometric review
Atmospheric cold plasma is an innovative, non-thermal technology. It has shown promising results for a broad range of food processing applications. On the basis of those facts, it has prompted growing attention in the scientific community. This paper reviews the literature generation trends surrounding the atmospheric cold plasma technology. A bibliometric analysis was carried out to objectively and analytically uncover the knowledge development in the atmospheric cold plasma technology within the context of meat processing. The research began with querying the Dimensions database for scientific articles published over the past two decades. A total of 105 papers were published during this period. The articles were examined according to several bibliometric metrics such as the year of publication, countries, institutions, sources, authors, and keywords frequency. The results of the bibliometric analysis revealed that researchers are very interested in studying the interface of the atmospheric cold plasma technology and meat processing. In the last couple of years, the number of publications on the topic has been growing. This is the first bibliometric investigation of the atmospheric cold plasma technology in the context of meat processing. To the authors’ best knowledge, no similar analysis has been performed before. This paper provides researchers with a better understanding of topic developments. A better understanding can aid future research by closing present knowledge gaps. Hence, the paper provides the continuation of up-to-date technological discussions among researchers
Effects of geoecological factors on vegetation of the Gruža basin
The paper presents the results of a study of the effects of geoecological factors on the vegetation of the Gruža basin (F=618.6 kmІ). In the first phase, geoecological factors were identified and their differentiation to physical geographic (geological structure, tectonics, relief, climate, waters, types of land) and anthropogeographic factors (activities of population) was carried out. In the second phase, their influence on vegetation was defined, and in the third phase, the condition in the Gruža basin was analyzed on the basis of topographic and thematic maps using GIS methodology
Geographical and biological analysis of the water quality of Moravica spring in the Sokobanjska Moravica drainage basin, Serbia
In this work we performed a geographical analysis of the Moravica spring locality in the Sokobanjska Moravica drainage basin in Serbia, as well as an analysis of the physical, chemical, and biological parameters of the water during a one-year period. The basic sanitary characteristics and physical, chemical, and biological parameters, necessary for understanding locality conditions, were studied, and the saprobity index, class of quality, O/H index, degree of saprobity, degree of trophicity, and category based on the phosphatase activity index (PAI) were determined. Our results point to the need for continual monitoring of the water quality in the spring locality

Color measurement of animal source foods
Rapid and objective assessment of food color is necessary in quality control. The color evaluation of animal source foods using a computer vision system (CVS) and a traditional colorimeter is examined. With the same measurement conditions, color results deviated between these two approaches. The color returned by the CVS had a close resemblance to the perceived color of the animal source foods, whereas the colorimeter returned not typical colors. The effectiveness of the CVS is confirmed by the study results. Considering these data, it could be concluded that the colorimeter is not representative method for color analysis of animal source foods, therefore, the color read by the CVS seemed to be more similar to the real ones
Exposure assessment to essential elements through the consumption of canned fish in Serbia
The aim of this study was to provide a quantitative exposure assessment to essential elements through the consumption of canned fish in Serbia. This objective was fulfilled by analyzing content of essential elements in canned fish and by using data from a food consumption survey. Consumption survey of canned fish was designed and performed to general principles and EFSA guidelines on data collection of national food consumption. The questionnaire was performed on 1,000 respondents during 2018. Determination of copper, zinc and iron levels were performed on 454 canned fish and seafood samples divided into four groups (canned tuna, canned sardines, canned other sea fish and canned seafood) during five consecutive years (2014–2018). This study showed significant association between sex, BMI and weight and consumption patterns. Obtained average weekly consumption of canned fish confirms our assumption that consumption of canned fish is significant in Serbia. Zinc and iron were found in all 454 samples (100%), and copper in 222 samples (48.9%). The average obtained concentration in all samples were 1.268 mg kg–1 for Cu, 5.661 mg kg–1 for Zn and 9.556 mg kg–1 for Fe. The highest concentration for all three minerals were found in canned sardines (Cu — 6.49 mg kg–1, Zn — 37.2 mg kg–1 and Fe — 21.8 mg kg–1). Obtained mean exposure to intake of copper, zinc and iron from canned fish was 1.2241 μg/kg bw/day, 5.4634 μg/kg bw/day and 9.2231 μg/kg bw/day, respectively. Exposure of Serbian population to zinc, copper, and iron through consumption of canned fish is less than recommended daily reference intakes and there is no risk of reaching toxic levels by consuming fish
Quantitative analysis and detection of chaptalization and watering down of wine using isotope ratio mass spectrometry
In early 1990's European Union has established new isotopic approach for detection of wine authenticity. In this article we setup the possibility of using new approach using new EIM - Module - IRMS (Ethanol Isotope Measurement - Module - Isotope Ratio Mass Spectrometry) instrumental technique and new analytical parameter delta D-n(delta H-2(n)) wine ethanol value, which represents delta H-2 value of non-exchangeable hydrogen stable isotope ratio in ethanol, with other isotopic species (delta O-18 values in wine water) to improve detection of illegal wine production practices such as addition of sugar and/or dilution with water. Total of 42 wine samples were analyzed. 10 wine samples (out of 42) were prepared from grapes by alcoholic fermentation and analyzed for delta D-n values of ethanol. 19 wine samples (out of 42) were collected from wine producers in Serbia plus 1 wine samples designated from United States was taken from Serbian market and analyzed for delta D-n values of ethanol, delta O-18 values in wine water and also delta C-13 values in wine ethanol. Furthermore 9 wine samples (out of 42) were taken from Hungarian market and analyzed for delta D-n values of ethanol, and also 3 wine samples (out of 42) were taken from Austrian market and analyzed for delta D-n values of ethanol. All experiments were done in 4 isotope laboratories located in US, Austria, Hungary and People's Republic of China. delta D-n values of ethanol were measured by using EIM Module connected to FlashHT 2000 pyrolizer (one laboratory - Imprint Analytics GmbH, Austria), while in other 3 laboratories (US - COIL - Cornell University, Stable Isotope Laboratory, Hungary - Isotoptech Ltd, Debrecen, Hungary and China - C.N.R.I.F.F.I. - China National Institute of Food and Fermentation Industries Limited) EIM Module was connected to TC/EA (High Temperature Conversion Elemental Analyzer). Peripherals in all laboratories were further interfaced with isotope ratio mass spectrometer. Furthermore delta O-18 values in wine water were measured by using Gas Bench II interfaced also with isotope ratio mass spectrometer (one laboratory - US). Obtained results from all 4 laboratories have shown that this new approach which uses delta D-n in wine ethanol is more effective in improving detection of illegal wine production practices (sugar enrichment and water dilution) and origin of ethanol, and also detecting the addition of corn or beet sugar, sugar syrup to wine, or dilution of grape must with water prior to alcoholic fermentation
Culinary preparation and processing of meat with wooden breast myopathy
Recently, poultry meat production and consumption has become increased worldwide. Decades of intensive selection in poultry breeding resulted in fast-growing broilers, improved food conversion, low production costs, and high yield of breast meat, as the most valuable part of the carcass. Some side-effects of intensive production and rapid growth of broilers include the appearance of myopathies in breast muscle. Increasing attention has been paid to the defect known as "wooden breast" (WB) due its incidence and severity of anomaly. WB is characterized by the hardness and pale colour of the fillet. These changes lower the consumer acceptance of the meat, and a pronounced WB is unsuitable for culinary and industrial processing. Different procedures can be used to tenderize the meat and include physical and chemical procedures, often combined in industry. Physical procedures comprise the application of heating, mechanical force, ultrasound, electric stimulation, hydrodynamic shock wave-pressure technology, high pressure processing, and pulsed electric field. Chemical procedures include marinating, exposure to the endogenous enzymes, and the use of exoenzymes. In the future, it is necessary to develop optimal tenderizing techniques or combinations of different tenderizing techniques to achieve better sensory quality and improved nutritional value of WB
Implementation of climate change science in viticulture sustainable development planning in Serbia
Growing interest in Serbia in adaptation of viticulture to climate change emerged from a recorded positive impact of summer increased draught on domestic wine quality. Another motivation is that viticulture has been recognized as one of the fastest developing agricultural sectors in Serbia and, to contain its growing potential, it is crucial to provide basis for its future sustainable development. Prioritization and implementation of adaptation measures in practice require reliable assessment of climate projections. For climate change impact assessment is used high resolution multi-model ensemble of nine regional climate models simulations, bias corrected, with two most probable future scenarios of GHG emissions RCP4.5 and RCP8.5, for the period 2016-2100. Analysis has been done for the near future, mid-century and end of the century periods. The periods are defined according to the IPCC 5th Assessment Report, which enables comparison of climate change impacts with a wider region, and preferably motivate future international collaboration and knowledge exchange
