Meanwhile, it was observed that the raising system differently changed the myofiber characteristics depending on the muscle group and the developmental stage. CRC Press LLC, Boca Raton, Sante V, Sosnicki AA, Greaser ML et al. Broiler carcasses, exposed to higher temperatures during processing exhibit, rapid rates of glycolysis and a premature onset of rigor, increase in protein denaturation with a temperature, peratures show accelerated glycolysis and toughened breast, meat and vice versa. The sensory quality of chicken breast meat and drumstick meat, expressed as color, structure, juiciness, tenderness, odor and taste acceptability was improved in experimental groups. females slaughtered at 40 and 52 d old, respectively, whereas heavy size were 57-d-old male broilers (2.4 kg of carcass weight; n = 90).

Genome-wide transcriptome analysis showed that compared with FRS, NRS induced the most extensive gene expression changes in breast muscle (BM) at W4 but in thigh muscle (TM) at W13, suggesting the asynchronous molecular responses of BM and TM to the raising system and period. >> The, poultry carcass temperature should be reduced to 4.4, less within 4–8 h in relation to the weight of the carcass, chilling may directly affect the water-soluble nutrients in, poultry meat with no signiﬁcant impact on proteins or, lipids. In the incubator, the eggs are kept under optimum atmosphere conditions and … /P 35 0 R Under the proper conditions, tenderness is well maintained, throughout the chilled/frozen storage life, but improper, chilling/freezing, can produce severe toughening and meat, argued that chilling methods can inﬂuence the quality and, visual appearance of carcasses which in turn affect their, overall acceptability and carcasses can absorb water, (4–6%) through the skin and surrounding fat in contrast to, air chilling. After slaughter, 15 carcasses per flock (n = 270) were randomly collected during winter (n = 135) and summer (n = 135) seasons and used at 24 h postmortem to determine breast (pectoralis major) meat color (lightness, redness, and yellowness), pH, drip and cook loss, as well as Allo-Kramer (AK) shear values. /Rotate 0 icant effect on protein, fat and vitamin levels. << 52 0 obj Poult, Pippen EL, Klose AA (1955) Effects of ice water chilling on ﬂavor, Raj ABM, Wilkins LJ, Richardson RI et al (1997) Carcass and meat, quality in broilers either killed with a gas mixture or stunned.

Our results showed that compared with FRS, NRS generally induced higher pH, lower lightness (L∗) and yellowness (b∗), lower drip loss and cooking loss, and lower shear force in either breast or thigh muscles during early posthatching stages but subsequently showed less pronounced or even reverse effects. 500 500 278 278 564 0 564 444 921 722 667 667 722 611 556 722 722 333 389 722 611 At the end (42 days age) 8 birds from each respective group (2 birds per replicates) were sacrificed for carcass characters and meat quality assessment. Biochemical and, ultrastructural observations. Although a number of nongenetic factors have been reported to be able to modulate skeletal muscle phenotypes in meat-type birds, neither the underlying mechanisms nor the muscle group–specific phenotypic and molecular responses have been fully understood. >> In order to meet the consumers’ growing demands for high-quality protein, the poultry industry focused on selection of fast-growing broilers, which reach a body mass of about 2.5 kg within 6-week-intensive fattening. >> Access scientific knowledge from anywhere.

The quantifiable properties of meat such as water holding capacity, shear force, drip loss, cook loss, pH, shelf life, collagen content, protein solubility, cohesiveness, and fat binding capacity are indispensable for processors involved in the manufacture of value added meat products. On the other hand, principal heme pigments, found in meat are myoglobin, hemoglobin, and cytochrome, lower myoglobin concentration than that of other species, content of the birds and stress immediately before and, during slaughter affects meat colour. /SA true myoﬁbrillar proteins along with environmental stress, scalding temperature, age of birds, rate of rigor develop-, ment, rate of chilling and ﬁlleting time.

Eight-piece-cut broiler parts were coated by use of one of three coating methods (flour predust-batter-flour, batter breading, or breading only), or not coated before deep-fat frying. Reduced proteolytic potential is likely to increase toughness of poultry meats. Dietary inclusion of vegetable oil, with or without quercetin was supplied to broilers for 35 days, in order to determine its influence on carcass characters and meat quality attributes. /Name (Headers/Footers) /Type /ExtGState Although, the reasons not fully clariﬁed, Wilkinson, ) investigated the impact of satellite cells in, ). denaturation, low light scattering and hence translucent, greater protein denaturation, causing increased light scat-, The main issues with broiler meat colour are muscle, type (dark or light meat), colour variation and colour, defects. << deposit pigments in the epidermis giving a white colour, irrespective of diet.

Though, fresh poultry, if chilled and stored under, ideal conditions, can have a shelf-life of 2–3 weeks, during. Because of the high percentage of red muscle fibres, waterfowl has no disposition for PSE-meat. Modified soups had significantly lower mean sodium content than their regular versions (28%-38%). Mean sodium content among modified salad dressings and cheeses was on average 8%-12% higher, while sodium content did not change with modification of savory snacks. Any stress shortly before or at, slaughter has been reported to cause PSE due to an, increased rate of post-mortem metabolism, accelerated, glycolysis, and pre-mature on set of rigor mortis.
