Zoonoses are diseases that can be transmitted from animals to man, either directly or via contaminated food. They are an extremely large group of human diseases with an extremely serious medical and economic impact, for which reason great attention is devoted to monitoring the incidence of zoonoses and their causative agents. The individual EU member … [Read more…]
Selected cuts of beef meat were evaluated – wing rib, top sirloin and flank – and their sensory properties compared during aging (30 days and 60 days). Measurement of the maximum Warner– Bratzler shear force determined that the meat became softer during aging, though this softening was not identical for all meat cuts tested. The … [Read more…]
The Vysočina sausage belongs to the category of dry heat treated meat products. The Czech legislation lays down qualitative requirements for this product, including a minimum content of pure muscle protein and a maximum content of fat. This study presents an analysis of 20 samples of Vysočina sausage from four different producers. Five different batches … [Read more…]
The quality of game meat is significantly influenced by the way in which the animal is treated after killing. The recommended way of treating mallard ducks is complete evisceration of the organs of the body cavity. The hygiene quality of meat may be assessed on the basis of changes in biogenic amine concentrations, an increase … [Read more…]
Biogenic amines are found in a large number of foodstuffs. Ingestion of a large quantity of biogenic amines in food may produce negative toxic symptoms in humans. Biogenic amine concentrations in meat are associated with the proliferation of contaminating microorganisms. An increasing concentration of biogenic amines serves as an indicator of the deteriorating hygiene quality … [Read more…]
Recent data from the European Union monitoring of zoonoses and zoonotic agents confirm that microbial contamination of meat, especially raw meat and fresh raw meat products, is one of the most relevant food safety issues. The most relevant foodborne pathogens (e.g. Salmonella spp., Campylobacter jejuni/coli, Yersinia enterocolitica, verocytotoxigenic Escherichia coli) can be harboured in the … [Read more…]
The microbiological quality of poultry products is dependent on a number of factors. The aim of this paper was to ascertain the influence of maintaining the cold chain on microbiological changes in three types of poultry products and their shelf lives. The samples were collected and tested on the day of production and on the … [Read more…]
The objective of this study was to evaluate the effect of adding a powdered extract of grapes on the quality of Poličan dry fermented sausages, and Vysočina dry non-fermented sausages. Samples of these meat products were prepared by the Department of Meat Hygiene and Technology, University of Veterinary and Pharmaceutical Sciences in Brno. The following … [Read more…]
The aim of this study was to evaluate the effect of soluble collagen on the texture of farmed fallow deer (Dama dama) meat. We evaluated two parts of the body (leg – Musculus gluteus medius, and shoulder – Musculus triceps brachii). The total content of collagen and soluble collagen and the texture parameters of selected … [Read more…]
The study involved samples of meat products enriched with unsaturated fatty acids and a natural antioxidant. After performing the basic physical, chemical, and sensory analyses, the oxidation processes were monitored by checking (TBARS) thiobarbituric acid reactive substances scores. The samples were not significantly different in terms of quality parameters, but definite differences were noted in … [Read more…]
