- СтавкаAttitudes and beliefs of Eastern European meat consumers – a review(2021) Tomasevic, I.; Solowiej, B. G.; Djordjevic, V.; Vujadinovic, D.; Djekic, I.Eastern European consumers are traditional meat eaters who are still not looking forward in order to substitute their traditional meat-based dishes with meat analogues or their substitutes. In general, vegetarianism is in its infancy if we do not take into account Lenten fasting, the period of the year when in Orthodox countries of Eastern Europe one can find food not containing meat, dairy and eggs, widely available. Chicken meat is the most frequently consumed type of meat, and it is preferred because it is easy to prepare. Eastern European meat consumers believe that meat from castrated pigs is of better quality, and one third of them is indifferent towards animal welfare issues. The highest proportion of Eastern European consumers (42.9%) believes that game meat has many health benefits, is rich in proteins and is more organic than other types of meat. However, two thirds of Eastern European consumers eat game meat less than once a year. Differences in attitudes and beliefs of Eastern European meat consumers compared to their Western European equivalents are evident.
- СтавкаChromium content in the meat of male Saanen goat kids from Vojvodina (Northern Serbia)(2019) Tomovic, V.; Jokanovic, M.; Sojic, B.; Skaljac, S.; Lazovic, M.; Vasiljevic, I.; Tomasevic, I.; Nikolic, I.; Vujadinovic, D.; Tomovic, M.Goats, the earliest ruminant to be domesticated, are traditional sources of meat, milk, fibre, leather, related products of animal origin and as draught and pack animals. Meat is the major product of the goat. Meat quality is the sum of all sensory, nutritive, technological and hygienic-toxicological factors of meat. The aims of this study were to investigate the chromium content of four different muscles (M. psoas major, M. longissimus dorsi, M. semimembranosus and M. triceps brachii) of Saanen goat male kids and to determine whether the chromium contents differed between the muscles. Chromium content was determined using inductively coupled plasma optical emission spectrometry (ICP-OES), after dry ashing mineralisation. The studied muscles did not significantly differ (P >0.05) with respect to chromium content. The chromium content ranged from 0.012 to 0.067 mg/100 g, with an average of 0.026 mg/100 g.
- СтавкаCulinary preparation and processing of meat with wooden breast myopathy(2021) Starcevic, M.; Boskovic, S.; Vujadinovic, D.; Rajcic, A.; Branković Lazic, I.; Baltic, B.; Baltic, M. Z.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.
- СтавкаEstimation of fat cover of bovine carcases by means of computer vision system (CVS)(2021) Simunovic, S.; Rajic, S.; Djordjevic, V.; Tomovic, V.; Vujadinovic, D.; Djekic, I.; Tomasevic, I.The aims of this study were to obtain percentages of meat and fat cover for SEUROP classification system reference images using a computer vision system (CVS) and to calculate classification intervals which could be used in the future for construction of cheap and easy to use classification devices for small slaughterhouses. Lowest percentages of fat cover were found for the first class marked as “low” (the lowest fat content) and they gradually increased to the last class marked as “very high” (the highest fat content). Based on the obtained results, decision making intervals were proposed. In the present study, classification only refers to classification of adult bovine animals based on fat cover.
- СтавкаMercury in female cattle livers and kidneys from Vojvodina, northern Serbia(2021) Tomovic, V.; Jokanovic, M.; Tomovic, M.; Sojic, B.; Lazovic, M.; Vasiljevic, I.; Skaljac, S.; Martinovic, A.; Vujadinovic, D.; Vukić, M.Concentrations of mercury (Hg) were analysed in livers (n = 26) and kidneys (n = 26) of female cattle (412–2502 days old) from farms for milk production in the area of Vojvodina. Concentration of Hg was analysed by ICP-OES, after digestion by microwave. The Hg concentrations in the livers and kidneys ranged from below detection limits (LOD < 0.006 mg/kg) to 0.206 mg/kg wet weight and from below detection limits (LOD < 0.006 mg/kg) to 0.018 mg/kg wet weight, respectively.
