Resumo: Objetivou-se com este trabalho avaliar as características físico-químicas e sensoriais da carne de caprinos das raças Canindé e Moxotó, criados em sistema de confinamento e alimentados a base de dietas com dois níveis de feno de maniçoba (Maninhot glaziovii muell.) (35 e 70%). Utilizou-se 40 cabritos castrados, dos quais 20 da raça Moxotó e 20 da raça Canindé. Cabritos da raça Moxotó produziram carnes com maior umidade e suculência que os animais da raça Canindé. Foram encontrados na carne destes genótipos avaliados, expressivos teores de proteína e baixas concentrações de lipídeos totais, o que é desejável para consumidores que priorizam produtos saudáveis. Pode-se afirmar que as carnes procedentes de caprinos da raça Moxotó e Canindé classificam-se como macias, e que, o fornecimento de dietas com maiores níveis energéticos para caprinos da Raça Moxotó e Canindé, em confinamento, favorece a produção de carnes mais macias e suculentas.

Abstract: The effect of rest periods during seasons was evaluated on morphogenetic and structural characteristics and herbage accumulation of Panicum maximum cv. Mombaca established in Amazonia. We used a completely randomized design, with four replicates per treatment. Rest periods were 36 and 48 days, and height of cut was 25 cm. Leaf blade dry matter production did not increase as rest period increased. Dry matter production did not modify between rest periods, showing that in the lowest rest period lower production was compensated by higher number of cuts. Rest period did not influence the morphogenetic variable evaluated, except phyllocrono as higher average was obtained in lower rest period. For structural characteristics, effect of rest period was observed for leaf blade dry matter production did not increase as rest period increased. Dry matter production did not modify between rest periods, showing that in the lowest rest period lower production was compensated by higher number of cuts. Rest period did not influence the morphogenetic variable evaluated, except phyllocrono as higher average was obtained in lower rest period. For structural characteristics, effect of rest period was observed for leaf blade length, death leaves number and sheat-stem ration.

The protease from Bacillus licheniformis, commercially known as Alcalase (R), was insolubilized and stabilized by immobilization onto activated chitosan. Activation with different agents, such as glutaraldehyde (GLU-Chi), glyoxyl (GLY-Chi) and divinyl sulfone (DVS-Chi) was investigated. The effect of the immobilization protocol, for instance different pH and times, were also evaluated. GLU-Chi showed the highest activity (35.6UNPA/g) with the smallest substrate (N-Boc-L-alanine p-nitrophenyl-ester, NPA), while GLY-Chi showed the highest activity (1.5 UAzocasein/g) using the greatest substrate (azocasein). A 24-h immobilization period was enough to stabilize the enzyme using the three supports under almost all conditions. Operational stability in azocasein hydrolysis was assayed and GLU-Chi showed no activity loss during 5 cycles. DVS-Chi retained around 70 % of its initial activity after the fifth cycle, whereas GLY-Chi activity retained only 10 %. Finally, the biocatalysts were used in the hydrolysis of tilapia skin gelatin aiming the production of peptides with antioxidant activity. The protein hy-drolysates obtained using GLU-Chi presented the highest antioxidant activity (36.7 mu M Trolox Eq). However, the best results of operational stability were obtained using DVS-Chi, which did not lose its initial activity after 3 consecutive cycles of gelatin hydrolysis. |
