Composição proximal e qualidade da carne de frangos das linhagens Paraíso Pedrês e Pescoço Pelado

Abstract: RESUMO -Neste trabalho foram avaliadas as características físico-químicas da carne de frangos de duas linhagens (Paraíso Pedrês e Pescoço Pelado) criados em sistema semiextensivo, machos e fêmeas, abatidos aos 65, 75, 85 e 95 dias. As características analisadas nos cortes peito e coxa foram umidade, proteína, extrato etéreo, cinzas, cor (CIEL*a*b*), pH final e perda de peso por cocção. As fêmeas da linhagem Paraíso Pedrês apresentaram no peito mais gordura (0,86%) em comparação aos machos das linhagens Paraíso… Show more

“…The results of the literature, in general, showed no influence of sex on the red contents (Fanatico et al, 2005;Lonergan et al, 2003;Santos et al, 2005;Souza, 2004). However, the values of this work are quite inferior to those reported by Fanatico et al (2005), with a* means of 3.92 and 3.94; Santos et al (2005), with 3.49 and 3.40 means and; Faria et al (2009) with mean from 4.58 to 5.30.…”

“…To determine cooking loss (CL), the breast samples were weighted in semi-analytical scales, METTLER M P1210 (Toledo, Brazil), wrapped in aluminum paper and submitted to cooking on an electrical plate at 150º C. When the samples reached 72º C they were removed from the plate, cooled at room temperature and weighted (AMASA, 1978;Souza, 2004;Faria et al, 2009). For the CL values used in the statistical analysis, the means of the differences between the weights before and after cooking each of the experimental units were obtained and converted into percentages.…”

“…Le Bihan- Duval et al (1999), evaluating chicken meat color, found a positive correlation between meat lightness and abdominal fat percentage, and suggested that the latter may reduce meat redness. According to Faria et al (2009), age at slaughter, genetics, and sex affect the chemical composition of chicken meat, and found lower b* values and higher a* values in the meat of males compared with females.…”
