The aim of the present work was to evaluate the effects of 2 different packaging films on chemical, physical, and microbiological variables in veal calf meat. Slices from the right half carcass were sampled from each calf: 8 were packaged with Cryovac film (25 μm thick) and 8 were packaged with Weegal film (45 μm thick). In both packaging types, the same gas mixture was used. The samples were a...

S OF PAPERS 199 shallow Al pan using a standard oven (163C) to an 85C internal breast. Prior to freezing, all crop and body cavities had been filled with bread cubes having 50% added water by weight to increase RTW by 20%. Each of 4 treatments involved 7 RTC carcasses: 7 thawed to +5C when cooking was initiated with frozen repetitions at -5, -15 and -25 to enable regression analysis. Time to at...

OBJECTIVE An experiment was conducted to study the blood haematology, muscle pH, and serum cortisol changes in pigs with different levels of drip loss. METHODS Two groups (low and high) of 20 animals were selected from 100 pigs based on drip loss. All [Duroc× (Large White×Landrace)] pigs were slaughtered according to standard slaughtering procedures. At exsanguinations, blood samples were tak...

The objective of the study was to characterize pale breast meat, compare it with normal colored breast meat, and determine whether it should be considered pale, soft, and exudative (PSE). Characteristics of 20 normal and 20 pale broiler breasts, obtained at a commercial slaughter plant, were evaluated. Compared with normal meat, the pale breast meat had a significantly (P < 0.05) lower pH (5.7 ...

To study the effect of processing on polybrominated biphenyl (PBB) levels, milk from four dairy herds containing less than 0.3 ppm (fat basis) of physiologically incorporated PBBs was presented individually into cream, skim milk, butter, and stirred curd cheese. Pasteurized and freeze-dried whole milk, skim milk, and cream, spray-dried whole milk and skim milk, and condensed whole milk were als...

OBJECTIVE The aim of this study was to investigate the expression of heat shock protein (HSP) 90, 70, and 60 in chicken muscles and their possible relationship with quality traits of meat. METHODS The breast muscles from one hundred broiler chickens were analyzed for drip loss and other quality parameters, and the levels of heat shock protein (HSP) 90, 70, and 60 were determined by immunoblot...

The effects of meat shape and size, freezing method and thawing temperature on the drip loss of beef brisket and the protein content of its thaw exudates were examined in this study. The beef brisket was cut into the following shapes: cube; brick-shape with rectangle cross-section; and brick-shape with square cross-section and were then frozen using a standard freezer (-15 oC), an air-blast fre...

The objective of this study was to compare postmortem meat quality traits and consumer acceptance of sensory qualities in Duroc, Landrace, Meishan, and Yorkshire pork, for both the fresh and cooked forms. A total of 134 pigs were evaluated. Meishan pork showed the lowest pH45 min and pH24 h values and the highest drip loss and lightness values. In the consumer evaluation of the fresh meat, the ...

The objective of the current review is to highlight biochemical processes and products, from slaughter to the time of beef consumption, that relate to response to stress at slaughter, meat quality and consumer health. Biochemical processes and products involved in the use of catecholamine and dopamine levels at slaughter, in predicting meat quality, are reviewed. Furthermore, meat quality chara...
