Foram mensurados o pH24horas, a capacidade de reten??o de ?gua, luminosidade (L*), teor de prote?na total, extrato et?reo, mat?ria seca, res?duo mineral fixo, teor de vermelho (a*), teor de amarelo (b*), croma (C*), matiz (H*), perdas de peso por cozimento, teor de col?geno total e sol?vel, ?ndice de fragmenta??o miofibrilar e for?a de cisalhamento. N?o houve efeito significativo (P>0,05) dos grupos gen?ticos sobre o pH24horas do LTL (5,64), do ST (5,72) e TB (5,85). Os valores de pH24horas do LTL, refer?ncia ? carca?a, estiveram dentro do intervalo de normalidade (5,3-5,7). Os grupos gen?ticos tamb?m n?o influenciaram, significativamente, o teor de extrato et?reo, os teores de prote?na e mat?ria seca, res?duo mineral fixo, teor de amarelo, o matiz, as perdas de peso por cozimento, o ?ndice de fragmenta??o miofibrilar, assim como o teor de col?geno total e sol?vel. A for?a de cisalhamento e a capacidade de reten??o de ?gua foram, no entanto, influenciados pelos grupos gen?ticos, observando maior maciez no grupo GH, em rela??o ao GN. A capacidade de reten??o de ?gua apresentou maiores valores para o grupo GN em rela??o ao grupo GH, o que n?o demonstrou impacto sobre as principais qualidades comerciais da carne. O teor de vermelho e o croma apresentaram intera??es entre os grupos gen?ticos e os m?sculos estudados, sendo a varia??o dentro do grupo GH, diferente dos demais grupos gen?ticos, apresentando valores menores no ST, em rela??o aos demais grupos gen?ticos, e, substancialmente, maiores valores no TB em rela??o aos demais m?sculos. Comparando-se as caracter?sticas entre os diferentes m?sculos, foram percebidas diferen?as significativas em todos os par?metros estudados, dentre elas a menor for?a de cisalhamento do TB, e tamb?m do ST em rela??o ao LTL. Tal fato talvez seja decorrente do maior teor de extrato et?reo, das menores perdas de peso por cozimento do TB e do maior ?ndice de fragmenta??o miofibrilar do TB e ST. Admite-se, tamb?m, que varia??es em par?metros, quando comparados LTL, ST e TB entre si, decorram de especificidades anat?micas e fisiol?gicas dos m?sculos que os originaram. Conclui-se que, os grupos gen?ticos apresentaram semelhan?a em quase todos os par?metros de qualidade estudados, demonstrando, por?m, menores valores de for?a de cisalhamento para o grupo GH. Foi tamb?m representativa a melhor qualidade do TB, medida por par?metros objetivos, em rela??o aos demais m?sculos estudados. / Disserta??o (Mestrado) ?

We measured the pH24hors, the ability to retain water, lightness (L*), total protein, ether extract, dry matter, fixed mineral residue, redness (a*), yellowness (b*), chroma (C*), hue (H*), cooking weight loss, total collagen and soluble, myofibrillar fragmentation index and shear force. There was no significant effect on pH 24hours (P> 0.05) between the genetic groups on the LTL (5.64), ST (5.72) and TB (5.85). The PH 24hours values of LTL, the reference substrate, were within the normal range (5.3 to 5.7). Genetic groups did not significantly influence the content of fat, the protein, dry matter and mineral, the yellowness, the hue, the weight losses by cooking, myofibrillar fragmentation index, as well as the content of total and soluble collagen. The shear force and the water retention capacity were influenced by genetic groups. The GH group was more tenderness than in the GN group. The capacity of water retention was higher in the GN group than in the GH group, which showed no impact on the main commercial qualities of meat. The content of red and chroma showed interactions among genetic groups and the muscles studied, and the variation in the GH group unlike other genetic groups had lower values in the ST and the other genetic groups had substantially higher values for TB compared to other muscles. Comparing the properties of the different muscles, significant differences were observed in all parameters studied, among them the lowest shear force of TB, and also the ST compared to LTL. This fact might be due to the higher content of fat, the less weight loss by cooking the TB and higher myofibrillar fragmentation index of TB and ST. Also it is assumed that variations in parameters when compared LTL, ST and TB among themselves, might be resulting of anatomical and physiological peculiarities of the muscles that originated them. We can conclude that the genetic groups were similar in almost all quality parameters studied, but lower values of shear force on the GH group. Also was relevant the best quality of TB, measured by objective parameters, compared to the other muscles studied.

It is understood this product as a potencial disseminator of other ingredients, which could improve their composition and structure and even enhance products from other supply chains as manioc. This is an important economic crop which accumulate starch in its roots. It has great importance for human nutrition and agroindustrial process. The objective of this research was to develop and characterize a product type hamburger with beef and manioc pulp. Burgers were developed with addition of manioc at four concentrations: 5%, 10%, 15% and 20% (w/w). The control consisted of hamburger obtained exclusively with beef. Analysis of moisture, fixed mineral residue, protein, iodine, weight loss by cooking, PH, shear force, a*,b*,L*,H? and C* of burgers. The analyzes were conducted at times of 0, 15, 30, 45 and 60 days post processing. The iodine parameters and red content (a*) were not significantly (P>0,05) influenced by the proportions of pulp or manioc added and the period of storage. Moisture, fixed mineral residue, pH and chroma (C*) were significantly lower over the storage time. The brightness of the product, the yellow content (b*), and hue (H?) have been higher (P<0,05) was added as larger amounts of manioc pulp. As for weight loss by cooking, shear force and protein content were significantly decreased (P<0,05) with the addition of manioc pulp. It is recommended the formulation of beef burger by adding 20% of manioc pulp, which was observed in less weight loss during cooking and less firmness, resulting in better texture, higher juiciness, preservation of sensory attributes and nutritional value, is also important in view of income to prepare for consumption.

These cuts were matured by the two maturation techniques (packed in polyethylene for vacuum technique and without packaging for dry technique) in a commercial standard cold chamber, with a mean temperature of 3?C and a relative humidity of 69% for 5 times , namely: 0, 7, 14, 21 and 28 days. The sections matured by the dry-ageing technique were tacked daily and sprayed with a 2% (v / v) solution of acetic acid. The vacuum technique cuts were sprayed with the same solution and immediately vacuum packed. At each maturation time, yields, shear force, color (L a* b* C and H ?), water retention capacity, weight loss by cooking, pH, superificial quantification of total and thermotolerant coliforms, the levels of protein, fat, dry matter and fixed mineral residue were evaluated. No differences (P> 0.05) were observed for the shear force, weight loss per cooking, pH, microbiological and bromatological parameters, during the 28 days of maturation, for both techniques. In the vacuum packed meat (P <0.05), chroma increase and decrease in water retention capacity were observed. The vacuum packed meat had the highest total yields (P <0.05) compared to dry-aged meat. Dry-aged meat had a higher water retention capacity and less weight loss per cooking compared to vacuum packed meat. Dry maturation for 21 days provided color stability without changes in the physical-chemical parameters and reduction in the shear force of the meat from the semispinalis thoracis muscle. The 28-day vacuum maturation provided a reduction in the shear force of meat from the semispinalis thoracis muscle.

This paper was drawn up on the results of two surveys. The first was conducted in order to evaluate the quality characteristics of meat from crossbred cattle Wagyu ? Angus (Red). The second was conducted in order to verify the effects of maturation titty rump Nellore at different temperatures (0 ? C and 4 ? C) and time (0 = fresh meat with 24 hours, 7, 14, 21 and 28 days ). In the first study we analyzed the meat of Longissimus thoracis, Semitendinosus and Triceps brachii obtained from the slaughter of castrated males and females, at 24 months old. The bones were measured in the Longissimus thoracis muscle to fat thickness, color of fat (L * a * b *, C, H?), rib eye area and score to the degree of marbling. The final pH were analyzed, water retention capacity, weight loss by cooking, shear strength, color (L * a * b *, C, H?), and the moisture content, dry matter, mineral residue fixed, protein and fat. Meat portions of Longissimus thoracis muscle were collected to evaluate the effect of seven days and 14 days of aging at the end pH, water retention capacity, weight loss by cooking, the shear force on the meat color (L * a * b *, C, H?) and fat color (L * a * b *, C, H?). For the meat of all muscles of no gender effect on the ultimate pH, water retention capacity, by cooking weight loss and protein content. The Longissimus thoracis females received the best score for marbling, showed higher fat content and lower shear strength and Longissimus thoracis males showed greater loin eye area. The maturation of the meat of Longissimus thoracis provided a reduction in shear force and increase in final pH. In the second study, cam portions (400 ? grams) were packed, vacuum, and stored in the cold room temperatures (0 ?C and 4 ?C). They were maintained at these temperatures for 7, 14, 21 and 28 days. They analyzed the pH, water holding capacity, cooking weight loss, shearing force, color (L *, a *, b *, C, M ?). There was no variation in pH as a function of temperature used. However, the pH increase during maturation time. It was observed variation in brightness of the flesh a function of temperature being lower in brightness aged meat at 0 ?C. The content of this red meat increased linearly as a function of aging time and was also influenced by the temperature of ripeness, being higher when aged at 0 ?C. The cooking weight loss also showed a linear increase over time of aging. The water retention capacity and shear strength showed a linear decrease over time of aging. Maturation for 28 days decreased the shear force of titty rump. It is recommended to mature titty rump for 28 days in temperature
