Antibacterial properties of TiO2, ZnO as well as mixed TiO2-ZnO nanoparticles coated low density polyethylene films on Staphylococcus aureus PTCC1112 were investigated. Bactericidal efficiency of 0.5, 1 and 2 Wt% for TiO2 and ZnO nanoparticles and also 1 Wt% mixed TiO2-ZnO nanoparticles with TiO2:ZnO ratios of 25:75, 50:50 and 75:25 were tested under UV and fluorescent lights exposure at two di...

Because of their inhibitory effects, selected probiotic Lactobacilli may be used as antimicrobial against some hazardous microorganisms responsible for spoilage of fresh minced beef (cattle) minced meat and camel minced meat. Lactic acid bacteria were isolated from camel meat. These included 10 isolates; 1 Lactobacillus fermenti, 4 Lactobacillus plantarum, 4 Lactobacillus pulgaricus, 3 Lactobac...

Fresh meat preparations, as fresh sausages, hamburger, minced meats etc, are susceptible to rapid oxidation and the consequent browning of meat red color compromises the product attractiveness. As a result for the producers, there is the drastic reduction of products shelf-life. In order to remedy such economic loss, the addition of some substances with antioxidant effect may represent a valid ...

The aim of the work was to determine the shelf-life and the microbiological quality of minced meat packaged in modified atmosphere (MAP, 20% O2, 5% CO2, 75% N2). Changes in the microflora and in the chemical characteristics were monitored for a total period of 10 days. Different samples of minced pork meat and of minced mixed pork and beef meat (50% w/w) were packaged and stored at +1-2ÆC. The ...

The high incidence of colon cancer in affluent societies has often been attributed to a high fat diet and, more in particular, the consumption of meat. The association of the consumption of meat and the intake of fat with risk of colon cancer was investigated in a prospective cohort study on diet and cancer, which is being conducted in the Netherlands since 1986 among 120,852 men and women, age...

A thermoplastically extruded snack was produced from different blends of corn grits and silver carp minced meat. Response Surface Methodology (RSM) was used to study the effect of fish meat content and to optimize the feed composition. Fourteen treatments from central composite design considering minced fish content (0-3 kg) and corn (7-10 kg) were used as the independent variables. The expansi...

The antimicrobial activity of essential oils of oregano, thyme, basil, marjoram, lemongrass, ginger, and clove was investigated in vitro by agar dilution method and minimal inhibitory concentration (MIC) determination against Gram-positive (Staphylococcus aureus and Listeria monocytogenes) and Gram-negative strains (Escherichia coli and Salmonella Enteritidis). MIC(90%) values were tested again...
