Although the application of nanotechnology provides numerous advantages related to food safety and quality, at same time it may present a potential risk not only human health, but can affect animals environment as well. Recent studies have shown that indeed there are reasonable grounds for suspecting nanoparticles toxicological effects on biological systems. Food-contact materials (FCMs) already market in some countries, therefore more data about engineered nanoproducts affecting health...

Summary In order to produce fermented sausages with prebiotic fibre and improved fatty acid composition, 16% of pork back fat was replaced inulin gelled suspension (I) linseed oil emulsion ( IO ). Physico‐chemical analysis, profiles, lipid oxidation, microbiological, textural, colour sensory analysis were carried out. The content lower in I (31.38%) (35.36%) modified compared control (44.37%) P < 0.05). had SFA MUFA higher PUFA an n‐6/n‐3 ratio (2.23) 0.05) α‐linolenic increment (5.74 g...

The effect of different modified atmosphere packaging regimes on the behavior Salmonella spp. minced meat was studied. Minced experimentally contaminated with a cocktail (S. Enteritidis, S. Typhimurium, Infantis and Arizonae), packaged under vacuum or initial headspaces containing 20%O2/50%CO2/30%N2 20%O2/30%CO2/50%N2) stored at 3±1°C for 12 days. Samples were analyzed spp., viable lactic acid bacteria count every third day. counts decreased during storage in all types, reductions about...

This study assessed the potential use of various physiological stress biomarkers as indicators carcass and meat quality traits in 240 pigs subjected to standard marketing conditions minimal stressful antemortem handling using Pearson correlations. The most important pork (pH temperature, water holding capacity, color) had limited correlations with metabolites (lactate, glucose), hormones (cortisol, adrenocorticotropic hormone), enzymes (creatine kinase, aspartate amino transferase, alanine...

The aim of this study was to determine the effects gender, slaughter weight, stocking density, lairage time and season on carcass meat quality parameters in a low-input production system. conducted 400 pigs (200 barrows 200 gilts) with live weight 115.0 ± 4.70 kg. Barrows had higher weights, fat thickness lower meatiness. Heavier hot cold thickness, meatiness, incidences pale, soft exudative (PSE) dark, firm dry (DFD) meat. Low density during transportation increased skin lesion score, pH45...

Abstract The production of traditional meat products has a considerable potential in the Republic Serbia, particularly small and micro (household) establishments. Among large number products, dry fermented sausages dried are most important commonly appreciated by consumers. There is, however, need for better standardization this sector, also implementation necessary food hygiene rules HACCP principles according to regulations. provisions Food Safety Law, stating flexibility, which would...

Listeria monocytogenes is a bacterium that pathogenic for man and most animal species. Listeriosis generalized infection starts after ingestion of the causative agent L. (Finlay, 2001). Food not properly thermically processed, long storage such food, food produced in inadequate hygienic plants, as well cooked-cooled ready to eat (RTE) ideal medium listeria multiplication. High risk originated from fish, fish products sea comprised of: molluscs (fresh frozen shellfish, crustaceans shelled or...

The goal of this study conducted in Serbia was to detect HEV pig liver samples from slaughterhouses, retail outlets, and environmental swabs over the course a year. All positive were measured expressed as gene copy numbers per gram sample, representative number sequenced using Sanger approach. A total 45 HEV-positive re-amplified nested RT-PCR employing CODEHOP primers targeting ORF2 (493 nucleotides). average prevalence genotype 3 all slaughterhouses 29%, while 44% animals younger than...

The meat industry has met new challenges since the World Health Organization classified processed in carcinogenic Group 1. In relation to this, functional food concept processing gained importance, especially reducing N-nitroso compounds and polycyclic aromatic hydrocarbons (PAHs) as an additional imperative, apart from usual fat salt reduction product enrichment with ingredients. PAH relies on control of smoking process, but there is also a possibility they could be degraded by means...

Abstract The aim of this study was to identify the prevalence pathological lesions in pigs from small‐scale farms and determine associations between hematological parameters, carcass meat quality slaughtered pigs. conducted on 625 (~115 kg) originating 20 farms. Any signs pneumonia, pleurisy, pericarditis, liver milk spots were recorded as present or absent. Complete blood count investigated. following parameters measured: live, hot cold weights, cooling loss, dressing percentage, backfat...

The microbial composition of Serbian traditional fermented sausages, Sremski and Lemeski kulen, was studied. dominant lactic acid bacteria in these products were Lactobacillus (77.1 54.3%, respectively) Leuconostoc (20.0 22.9%, respectively). kulen characterized by a high percent Lactococcus (20.0%). most abundant species Lb. brevis (61.5 57.9%, contained pentosus (11.5%) salivarius (7.7%), contrast to which curvatus ssp. (15.8%). paracasei, plantarum fermentum present similar percentages...

Abstract The aim of this study was to evaluate the effects carvacrol and eugenol, separately in combination, on survival Listeria monocytogenes , sensory microbiological characteristics vacuum packaged Oncorhynchus mykiss during refrigerated storage (4 ± 1 °C) for 20 days. control fish fillets were analyzed microbial (total mesophilic psychrotrophic bacteria lactic acid bacteria) properties. Fish treated with carvacrol, their combination displayed populations L. significantly lower, by...

Abstract Staphylococcus aureus ( S. ) is the most common agent of contagious mastitis that causes serious health and economic problems. The ability to form biofilms an important virulence factor for establishment persistent infections. This study aimed investigate presence icaA icaD, two genes importance biofilm formation in bovine isolates. In order isolate identify , 1555 milk samples were collected from 401 cows, located different regions Republic Serbia. Using conventional...

Abstract Poor animal welfare is a growing issue of concern all over the world. During pre-slaughter phases, some activities, if poorly performed, lead to stress reactions in animals. Animals’ responses great extent depend on species, breed, sex and age animal. Food water deprivation, exposure unfavourable environmental conditions, improper handling social mixing are just indicators compromised well-being. All these detrimental activities development carcass meat quality defects. Among them,...

Sremski kulen is a wide diameter dry fermented sausage, produced from pork, seasoned with red spicy paprika, stuffed into pork cecum, and preserved by smoking, fermentation drying. Due to specific ripening process, suitable for the accumulation of biogenic amines. Therefore, aminogenesis was studied in traditionally kulen, taking account physicochemical parameters microbial counts. The content six amines (tryptamine, phenylethylamine, tyramine, histamine, putrescine, cadaverine) analyzed...

The 42-day long study was performed on a total number of 48 Hybro broilers divided into four groups. After the pre-experimental period 14 days, 3 experimental groups (n=12) were formed and fed diets that contained 0.5, 1.0 1.5 mg/kg ochratoxin A (OTA) during next seven consecutive days. In same period, control group diet with no toxin added. addition, blood samples taken from 6 animals in each group. remaining (n=6) without OTA until 42nd day study, when again. level serum proteins affected...
