Considering the increased incidence of wooden breast myopathy in broilers, the intake involves no threat to human health, indefinite etiology consumer rejection by appearance in such breasts, and the lack of studies on the industrial use of wooden breast. The objective of this study was evaluating the quality of hamburgers made with chicken meat affected by wooden breast. Breast samples from broilers slaughtered at 48-days-old were used. Normal (absence of myopathy), moderate degree (hardness only in one region of the breast) and severe degree (hardness over the entire length of the breast) samples were processed for the manufacture of hamburgers whose quality analyses (color, pH, cooking weight loss, shrinkage percentage, tenderness, storage weight loss, water activity, lipid oxidation, chemical composition and consumer test) were performed on non-stored samples (Day 0), and after storing at 30, 60, 90 and 120 days at −20 °C. There was a reduction (p < 0.05) in tenderness in samples of moderate-grade hamburgers (from 161.45 N to 289.40 N) after 120 days of storage. Hamburgers produced with chicken breast samples affected by wooden breast myopathy presented higher (p < 0.0001) fat concentration (5.32 g/100 g and 5.26 g/100 g, respectively, for the moderate and severe degree) than hamburgers made of normal samples (4.45 g/100 g). Lipid oxidation values increased, which exceeded the limit of rancidity detection, independent of myopathy. The consumers equally appreciated the aroma, flavor, and texture, and rated their overall acceptance as similar regardless of the quality of chicken meat. Chicken breast hamburgers with wooden breast myopathy is a viable alternative for the poultry industry.

Chicken Breast Meat

The aim of this study was to examine the effects of storage on the quality of sausages made with breast from chickens affected by wooden breast myopathy (WBM). Breast samples from male broilers slaughtered at 48 days old were used. Normal (absence of myopathy), moderate degree (hardness only in one region of the breast) and severe degree samples (hardness over the entire length of the breast) were processed into sausages and evaluated prior to storage and after being vacuum-packed and stored for 7, 14, 21 and 28 days at 4 °C. There was a decrease (p < 0.001) in pH and an increase (p < 0.001) in cooking weight loss in samples of sausages, regardless of the myopathy, after 28 days of storage. Sausages produced with chicken breast samples affected by wooden breast myopathy presented higher (p < 0.0001) moisture concentration (72% for the severe degree) and higher (p = 0.0224) protein concentration (17.27% and 17.36%, respectively, for the moderate and severe degrees) than sausages made of normal samples (70.72% and 14.32%, respectively). The results indicate that sausages produced with meat from birds moderately and severely affected by the myopathy show higher oxidative stability. Fresh sausages produced with breast meat from birds affected by wooden breast syndrome may be stored (4 °C) for up to 28 days without exhibiting the characteristic rancid taste and smell. In sensory analysis, no differences were observed between the formulations, which suggests that the consumers approved the samples regardless of the disease severity in the meat used for the making of the sausages. The current results show that chicken meat affected by wooden breast myopathy can be used for producing fresh sausages in the industry.

This study aimed to evaluate the effects of aging on the quality of breast meat from broilers affected of wooden breast. Samples that were classified as normal (control), moderate (hardness verified only in one region of breast fillet), and severe (hardness verified in all the extension of breast fillet) were evaluated fresh and after three and seven days of aging. Normal samples and samples with a moderate degree of myopathy showed greater water-holding capacity, which may benefit the processing industry of poultry meat. During the aging process, increase was observed in total collagen concentration (from 0.41% in normal samples to 0.56% in samples with severe degree). Samples of chicken breast affected by moderate degree showed higher myofibril fragmentation index (MFI = 115) than normal chicken samples (95.65). Although chicken samples affected with severe degree of wooden breast myopathy are more tender than normal chicken breasts, they produce more exudate, which can be detrimental to the processing of poultry meat. The aging process may improve the reduction of cooking weight loss and protein loss in exudation of broilers’ breasts affected by wooden breast myopathy.

We evaluated the effect of freezing (−18°C) for 12 months on the qualitative characteristics of breast, thigh and drumstick meat. Samples from male Cobb 500 broilers raised in antibiotic-free (n = 125), conventional (n = 125) and organic (n = 125) rearing systems and samples from male Hubbard ISA broilers raised in a free-range (n = 125) rearing system were used. Among the studied systems, up to the ninth month of freezing, the organic chicken breast meat showed lower (P < 0.001) water activity (aw) (0.966, on average). After 12 months of freezing, samples of antibiotic-free and organic poultry showed a pH value similar to that of fresh meat (5.94 and 5.86, respectively). Freezing for 12 months preserved the redness of drumstick meat from conventional broilers (a* = 4.86, on average) and the rearing system did not influence the aw of drumstick meat during the entire experimental period. Freezing preserved the aw of conventional and organic chicken meat samples until the ninth month of evaluation (0.978 and 0.974, respectively). Lipid oxidation in the breast, thigh and drumstick samples from the four rearing systems increased (P < 0.001) from the third month of freezing onwards. There were variations in colour, pH, aw and lipid oxidation of chicken meat among birds raised in different rearing systems. Freezing chicken meat did not prevent colour and pH changes or occurrence of lipid oxidation and did not promote a reduction of aw to levels unfavourable to microbiological development.

This study aimed to characterize the effects of wooden breast myopathy (WBM) on quality of broiler chicken breast meat. Normal samples (absence of myopathy), moderate-degree samples (hardness only in one area of the breast fillet) and severe-degree samples (hardness throughout the breast fillet) were classified. In macroscopic analysis, the pectoral muscle affected by the WBM showed, in general, pale color with stiff, irregular and reddish regions (suffusions and petechiae), with the presence of white striations. In microscopic analysis, the myopathy was characterized by loss of the polygonal aspect of the muscle fibers. Samples with moderate degree of the myopathy showed greater (p = 0.0266) water retention capacity. There was an increase (p = 0.004) in total collagen concentration in samples from the severe-degree group 0.29% in normal samples to 0.43% and 0.48% in samples from moderate- and severe-degree groups, respectively. Samples of chicken breast affected by the severe-degree WBM showed lower (p < 0.0001) myofibrillar fragmentation index (64.51) and lower (p = 0.0002) fat concentration (2.17%) than normal chicken samples (80.45 and 3.79%, respectively). Samples affected by WBM are larger and heavier and present poorer physical quality when compared to normal chicken meat. Histologically it is possible to observe loss of the polygonal aspect of muscle fibers.

Introduction: Chicken meat is a source of protein in the human diet. Protein content and values define the quality of chicken meat. This research aimed to analyze variations of protein profiles in chicken breast muscles from different slaughtering houses by using proteomic strategies. Methods: Total proteins of chicken breast muscles from three different slaughtering houses (Sample A, Sample B and Sample C) were extracted and quantified by using Bradford assay. Then, the proteins were separated by SDS-PAGE to monitor the quality of extracted proteins. Protein profiles in different samples were compared by 2D-GE analysis. Results: The most highly expressed protein band was located between the molecular size of 37-50 kD in all samples and it was expected to be betaactin. While resolved in 2D-PAGE, differences in protein expression were observed between samples. There were three spots expressed with highest intensity in Sample B compared to others. The protein spot detected at pH 5.28 and the size range between 50- 75 kD was predicted to be NADPH-cytochrome P450 reductase (CPR), at pH 6.45 and molecular weight between 37-50 kD was expected to be creatine kinase M-type (M-CK) while at pH 6.78 and molecular size nearly 25 kD was expected to be αB-crystallin. Conclusions: It can be mentioned that these proteins could play a vital role in mechanisms that contribute to the poor quality of chicken meat.

The effect of active compounds (ACs), allyl-isothiocyanate (AITC) and carvacrol (CARV), as natural additives on the quality of fresh chicken meat was evaluated. The meat was treated with 500 and 1000 ppm of ACs, vacuum packaged and stored at 4°C up to 8 days. Physicochemical characteristics, lipid oxidation, microbiological status, sensorial electronic-nose based properties were examined. AITC, particularly 1000 ppm, showed greater activity than CARV and resulted in colour changes, accumulative odour production, triggered reduction in the growth of Pseudomonas lundensis, Staphylococcus aureus, and Bacillus cereus and 3 log10 CFU/g reduction in aerobic mesophilic counts. However, CARV was more active in increasing chroma properties and reducing the growth of Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella typhimurium. Concomitantly, 500 ppm CARV showed greater activity than AITC in controlling lipid oxidation and protecting the colour changes. Therefore, both AITC and CARV possess great potential to extend the shelf life of meat and meat products.

The crispiness is an important parameter of battered chicken meat products and could be improved by adding leavening agents such as baking powder and dried yeast. This work was aimed to study the effect of different leavening agents added on the quality characteristics of battered chicken meat. Chicken breast meat strips were dipped into batters using different type of leavening agent; control (without a leavening agent); 4% baking powder (1), 4% dried yeast (2) and 2% baking powder + 2% dried yeast (3). The batter was kept in room temperature (RT) and cold temperature (CT) for one hour after coating. Moisture content, fat content, the viscosity of batter formulation, color, texture and sensory of fried battered chicken meat strips were evaluated. Moisture contents of RT3 and CT3 were significantly higher compared to other treatments while the fat content and viscosity of RT3 and CT3 were among the lowest. The RT2 and CT2 resulted in the lightest color. Compared to control samples, the addition of baking powder and yeast increased crispiness (fracturability and hardness) which was higher when used in combination than alone. Sensory evaluation of quality attributes showed crispiness and overall acceptability for RT3 and CT3 were among the highest. From the experiment, formulation 3 displayed the best effect of the leavening agents (a combination of baking powder and dried yeast) in batter system which produced lower fat, high moisture content, and crispier deep-fried chicken breast meat.

The aim of this study was to characterize the breast meat from broilers affected by the white striping myopathy and examine its influence on meat quality. 180 breast samples from male broilers, slaughtered at 42-d-old, were used. Samples were classified according to the severity degree of apparent white stripes on the Pectoralis major muscle surface (“normal” [n=60], “moderate” [n=60], or “severe” [n=60]). Birds affected by the myopathy produced breast meat with higher L*, a* and b* values on the outer surface. Cooking loss decreased as the severity degree increased (30.94% [normal] to 21.65% [severe]). Toughness increased in the samples classified as moderately and severely affected. There was also an increase in the concentrations of lipids (1.60% [normal] to 2.57% [affected samples], on average), cholesterol (84.60 mg/100 g [normal] to 91.73 mg/100 g [severe degree]) and collagen as the severity degree increased. Although there are statistical differences for some evaluated parameters and, even so, these results are considered numerically normal based on previously published literature, we emphasize that the white striping abnormality alters chicken breast meat quality, especially regarding to the protein and fat concentrations, which can offer consumers products with nutritional quality different from the average specified on the packaging.

Abstract High environmental temperature due to climate change can accelerate oxidation of feed during storage and preparation. Oxidized feed can cause elevated oxidative stress in live birds, resulting in decreased productivity and meat quality of broilers. The study was aimed to determine effects of feed containing oxidized oil on growth performance, plasma oxidative stress, and breast meat quality of broilers. Male broilers (192; Cobb500) at 21 days old were randomly allotted to 32 pens (8 pens/treatment) and raised for 21 days. The birds were fed feed containing fresh (Control) or oxidized corn oil (5%, Peroxide Value:140) with or without vitamin E (500 IU/kg feed) supplementation. Growth performance, oxidative stress markers in plasma collected at Day 42, and quality parameters of breast meat harvested at Day 43 were determined. Data were analyzed using proc glm and means were compared using Tukey’s studentized range (HSD) test. Oxidized feed and/or vitamin E supplementation did not affect growth performance and plasma DNA and protein oxidation. Oxidized feed significantly increased lipid oxidation and reduced total antioxidant capacity in plasma (P &lt; 0.05) and, interestingly, dietary vitamin E made them worse (P &lt; 0.05), indicating that oxidized lipids in feed can induce oxidative stress in live birds and vitamin E may act as a pro-oxidant in highly oxidized conditions. Although they did not affect sensory and functional properties of chicken breast meat, oxidized feed significantly increased lipid oxidation in cooked meat (P &lt; 0.05) but dietary vitamin E considerably inhibited its development (P &lt; 0.05), indicating that oxidized oil and vitamin E in feed can be accumulated in muscle and act as a pro- and anti-oxidants in meat, respectively. The results suggested that oxidized oil in feed can increase oxidative stress in live birds and susceptibility of breast meat to lipid oxidation, and dietary vitamin E can improve its oxidative stability.

Across the world, as well as in Croatia, there is a continuous increase in the consumption of chicken meat, and attempts are being made in modern poultry production to improve its quality as much as possible by using various natural additives. The aim of this study was to determine the influence of dietary supplementation with propolis and bee pollen on the quality of chicken meat. In order to determine this effect, the carcass body weight of slaughtered chickens and carcass yield were determined, as well as the average pH1 and pH2 of chicken breast muscle, drip loss values, and skin color and chicken breast muscle color expressed as values of L* (lightness), a* (redness), and b* (yellowness). The study was conducted on 200 Ross 308 chickens, divided into five groups. Throughout the study, the control group of chickens was fed with a basal diet, while the experimental groups of chickens were fed with the basal diet supplemented with propolis and bee pollen, each supplement given separately or in combination in specific proportions. At the end of the experiment (42nd day), 10 chickens from each group were slaughtered for the analyses mentioned above. The carcass yield values were significantly higher (P = 0.038) and the drip loss values were significantly lower (P = 0.003) in the experimental groups in comparison to the control group. In addition, there was a statistically significant difference in b* skin color (P = 0.017) and b* chicken breast muscle color (P<0.001) between the groups of chickens. The study showed that dietary supplementation with propolis and bee pollen has a significant positive effect on the quality of chicken meat.
