The imidazoquinoline and imidazoquinoxaline food mutagens found in cooked meat are being synthesized by unambiguous methods that allow for the preparation of sufficient quantities of material for biological studies. These methods avoid difficult separations of regioisomeric mixtures of products and are designed to allow incorporation of specific high level tritium labeling.

The aim of this study was to evaluate the effect of modified atmosphere packaging (MAP) on biogenic amine production in turkey meat according to its shelf life period, determining an index of freshness. Sliced meat samples of different meat quality categories (according to color and pH₂₄) were individually packaged under aerobiosis (aerobic package) and in 6 different modified atmospheres conta...

The main aim of the present work was to find out whether intensive fattening of pheasant poults can provide high-quality pheasant meat. The study is a pilot work in this area because until now pheasant rearing has only produced pheasants for the purpose of hunting. In this experiment three feeding mixtures were designed; nutritional and energetic composition of the mixtures complied with the re...

The current study aimed to examine a real-time PCR assay with high-resolution melting (HRM) analysis for the species identification of minced meat samples. Meat samples from several animal were purchased and separately or as mixture two species. DNA was extracted all subjected by amplifying species-specific mitochondrial cytochrome b regions. Regarding mixtures, separate curves specific melt pe...

in the present work, the integral equations method is used to calculate transport properties of polar fluids. for this goal, we use the stockmayer potential and examine theoretically the thermal conductivity of several refrigerant mixtures such as r125+r134a, r125+r32, r125+r152a, r134a+r32, r152a+r32, r134a+r143a, and r125+r143a. we solve numerically the ornstein-zernike (oz) equation using th...

This paper describes research on the electrical stunning of poultry and the problems of achieving an effective humane stun with water bath stunners. The welfare and meat quality advantages of using gas mixtures to stun and kill birds are then described. The evidence strongly suggests that chickens and turkeys can be killed very humanely using either 90% argon in air or a mixture of 30% carbon d...

The high beef price triggers adulteration of and other non-halal animal meat, such as wild boar rats. An appropriate effective analytical method is needed to differentiate halal meat. SPME/GC-MS could authenticate meat based on specific volatile compounds in each objective this study was characterize determine the marker raw beef, rat, their mixtures using SPME/GC-MS. chemometrics principal com...

Mechanisms of superoxide.O2--generating systems on the pro-oxidant effect of iron from various sources were studied. Reaction mixtures were prepared with distilled water, oil emulsion, or meat homogenates. Free ionic iron (ferrous and ferric), ferritin and hemoglobin (Hb) were used as iron sources, and KO2 and xanthine oxidase (XOD) systems were used to produce .O2-. Thiobarbituric acid reactiv...

The purpose of the present study was to evaluate the effects of soybean selenium proteinate on Se tissue retention and meat quality in pigs. In group A (n = 11) the mixtures were supplemented with soybean selenium proteinate, in group B (n = 11) with sodium selenite and in group C (n = 11) with Se-enriched yeast (0.3 mg Se per kg in all groups). The use of soybean selenium proteinate resulted i...

Utilization of agricultural waste can be done by converting it with conventional fuels to energy. For this purpose, is necessary understand the properties and its mixture fossil important for storage conversion. The objective work was examine influence moisture content composition hard coal mixtures on mechanical rheological waste. materials tested were powdered biomass: dried distillers grains...
