Astaxanthin, classified as a xanthophyll, has antioxidant properties about 500 times greater than α-tocopherols and ten β-carotenes. Based on the activity of this carotenoid, study aimed to evaluate shelf-life tilapia fillets (Oreochromis niloticus) fed with astaxanthin, by determining microbiological quality (colimetry, counts mesophilic psychrotrophic microorganisms), physicochemical analyses (colorimetry, pH, thiobarbituric acid reactive substances (TBARS)) sensory analysis.Tilapia...
This study aimed to characterize the effects of wooden breast myopathy (WBM) on quality broiler chicken meat. Normal samples (absence myopathy), moderate-degree (hardness only in one area fillet) and severe-degree throughout were classified. In macroscopic analysis, pectoral muscle affected by WBM showed, general, pale color with stiff, irregular reddish regions (suffusions petechiae), presence white striations. microscopic was characterized loss polygonal aspect fibers. Samples moderate...
This study aimed to evaluate the effects of aging on quality breast meat from broilers affected wooden breast. Samples that were classified as normal (control), moderate (hardness verified only in one region fillet), and severe all extension fillet) evaluated fresh after three seven days aging. Normal samples with a degree myopathy showed greater water-holding capacity, which may benefit processing industry poultry meat. During process, increase was observed total collagen concentration...
The objective of the present study was to characterize possible variations in quality wooden chicken breast meat during freezing for 12 mo, order prove whether shelf life recommended by industry allows storage that type without compromising its consumption. Three hundred samples male Cobb 500 broilers slaughtered at 42 d age were used. Part (n = 20 normal—control group; n moderate degree; severe degree) analyzed on day collection (beginning), previously kept under refrigeration (4°C). other...
The aim was to assess the impact of long-term storage on quality Botucatu rabbit meat frozen in pre- and post-rigor stages. stability technological nutritional parameters Longissimus lumborum (LL) muscle analyzed over 12 months. In phase, dorsal LL surface showed a higher level (p < 0.05) redness saturation, while ventral yellowness compared pre-rigor muscle. During storage, saturation decreased 0.05), increased both surfaces. first six months, had pH meat. fresh shear force values stage....
The aim of this study was to evaluate possible changes in the quality chicken breast meat containing white stripes during freezing for 12 mo. Samples Pectoralis major muscle from male Cobb 500 broilers moderate and severe degrees were used, as well samples a control group (normal - absence myopathies). Part (n = 60; n 20 each severity degree) analyzed on day collection (beginning) rest 240) frozen (-20°C) up At end proposed period (3, 6, 9, mo), color, pH, water holding capacity, cooking...
Deep pectoral myopathy (DPM) considerably affects the meat quality of commercial poultry, thus representing a challenge to poultry industry. In this study, we examined breast turkey breeder hens at disposal age affected by different degrees DPM. Samples were collected from Nicholas turkeys (385 d), an average weight 12.5 kg, which reared and slaughtered in south region Brazil. The was first classified according degree DPM then samples Pectoralis major birds (DPM 2 3; n = 20 each) nonaffected...
Considering the increased incidence of wooden breast myopathy in broilers, intake involves no threat to human health, indefinite etiology consumer rejection by appearance such breasts, and lack studies on industrial use breast. The objective this study was evaluating quality hamburgers made with chicken meat affected Breast samples from broilers slaughtered at 48-days-old were used. Normal (absence myopathy), moderate degree (hardness only one region breast) severe over entire length...
The aim of this study was to characterize the breast meat from broilers affected by white striping myopathy and examine its influence on quality. 180 samples male broilers, slaughtered at 42-d-old, were used. Samples classified according severity degree apparent stripes Pectoralis major muscle surface (“normal” [n=60], “moderate” or “severe” [n=60]). Birds produced with higher L*, a* b* values outer surface. Cooking loss decreased as increased (30.94% [normal] 21.65% [severe]). Toughness in...
One of the current myopathies affecting chicken meat industry is deep pectoral myopathy (DPM), also known as green muscle disease or Oregon disease, condition considered a major problem in poultry processing lines. Thus, present study proposes to examine quality Pectoralis (breast fillet) from carcasses broilers affected by DPM minor (tender) and control group. Breast fillets samples were harvested Ross AP95 that slaughtered at 42 days age selected occurrence (score 2 score 3) group without...
The increase in the consumption of poultry meat intensified production, which allowed emergence myopathies associated with broiler and turkey meat. aim to examine possible quality alterations 240 Pectoralis major muscle (breast fillets) from carcasses breeder hens. Regarding DPM, 120 samples breast fillets Nicholas strain minor together were selected according occurrence myopathy (tender), as follows: DPM score 2 (n = 40), 3 a control group unaffected by 0 40). Then, different samples, same...
The aim of this study was to examine the effects storage on quality sausages made with breast from chickens affected by wooden myopathy (WBM). Breast samples male broilers slaughtered at 48 days old were used. Normal (absence myopathy), moderate degree (hardness only in one region breast) and severe over entire length processed into evaluated prior after being vacuum-packed stored for 7, 14, 21 28 4 °C. There a decrease (p < 0.001) pH an increase cooking weight loss sausages, regardless...
The purpose of the present study was to characterize chemical composition, lipid oxidation, and physical characteristics fresh sausages produced with meat from pectoralis major muscle affected by deep pectoral myopathy. For characterization myopathy, samples were collected broiler chickens slaughtered between 42- 46-days old in a slaughterhouse state São Paulo. experiment consisted birds or not DPM (normal-absence myopathy category 3-progressive degeneration minor greenish appearance). After...
The aim of this study was to examine the effects frozen storage for 12 months on concentrations lipids and cholesterol fatty acid profile wooden chicken breast meat. 120 samples breasts were selected, according degree "wooden breast" myopathy ["severe", "moderate" "normal" (absence myopathy)], from male chickens slaughtered at 42 days age, Cobb 500 strain. Part (n=20/grade severity) evaluated day collection remainder packaged, stored -18°C up months. At beginning (collection day) end...
