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…]
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…]
Both oregano essential oil (OEO) and caprylic acid (CA) are highly aromatic natural antimicrobials; their individual application in food is therefore limited. Their combined additive effect we proved previously in vitro. Following mixtures (v/w) were tested in minced lean beef inoculated with 6 strains of L. monocytogenes at concentration of 5 log cells/g: 0.25% of … [Read more…]
