Resumo: A pesquisa teve como objetivo avaliar a qualidade da carne de tambaqui com diferentes pesos de abate. Foram utilizados vinte e quatro tambaquis, entre 1,0 e 3,5 kg. O peso ao abate não afetou o pH da carne (6,42), a cor para luminosidade (L*), intensidade de vermelho (a*) e amarelo (b*), respectivamente, com médias de 62,00; 2,86 e 15,57; e os atributos sensoriais aparência (7,41), sabor (7,25), textura (7,40) e aceitação global (7,24). A perda de peso por gotejamento e descongelamento

... a capacidade de retenção de água da carne de tambaqui foram afetados (P<0,01) pelo peso ao abate. Embora o peso de abate do tambaqui entre 1,0 e 1,5 kg apresente maiores perdas de água, as demais características qualitativas da carne não foram comprometidas.

Twenty-four animals were slaughtered at body weights ranging from 1.0 to 3.5 kg. The slaughter weight did not affect meat pH (6.42), luminosity (L*), red color intensity (a*) or yellow color intensity (b*) (means of 62.0, 2.86 and 15.57, respectively), nor the sensory attributes appearance (7.41), flavor (7.25), texture (7.40), and overall acceptance (7.24). Weight loss by dripping and defrosting and the water holding capacity of tambaqui meat were affected (P<0.01) by slaughter weight. Although a slaughter weight of tambaqui between 1.0 and 1.5 kg was associated with further water loss, the other meat quality traits were not compromised.
