Capacidade hidrolítica de alcalase versus novo pro D na hidrólise de CMS de tilápia. Repositório Alice
ANTUNES, A. B.; ATANASIO, N. M.; BRIGIDA, A. I. S.; GOMES, F. dos S.; SILVA, C. M.; STEPHAN, M. P..
A hidrólise enzimática parcial das proteínas de carne mecanicamente separada (CMS) de tilápia pode incrementar suas propriedades funcionais agregando valor e tornando esta uma boa alternativa para o aproveitamento destes resíduos agroindustriais. Assim, duas enzimas foram investigadas quanto ao seu potencial catalítico de hidrólise em CMS de tilápia, Alcalase® e Novo Pro-D®. Durante 5 horas de reação o grau de hidrólise foi acompanhado e, em tempos pré-definidos, frações do meio reacional foram coletadas. As amostras foram analisadas quanto sua atividade antioxidante, capacidade emulsificante, teor de aminoácidos aromáticos livres e perfil proteico. Embora Novo Pro D® tenha apresentado maior grau de hidrólise (55%) frente à Alcalase® (42%), esta última...

Dietary protein hydrolysate and trypsin inhibitor effects on digestive capacities and performances during early-stages of spotted wolffish: Suggested mechanisms ArchiMer
Savoie, A.; Le Francois, N. R.; Lamarre, S. G.; Blier, P. U.; Beaulieu, L.; Cahu, Chantal.
Growth rate is dependent upon adequate provision of amino acids especially in newly-hatched fish which experience very high growth rate. The replacement of a fraction of protein content by partially hydrolyzed (pre-digested) proteins was carried out and the digestive capacities and performances of larval/juvenile spotted wolffish (Anarhichas minor) were measured. The goal of this study was to verify whether the scope for growth is principally dictated by the proteolytic capacity of the digestive system by examining the effect of protein hydrolysates (PH) and trypsin inhibitor dietary inclusion on protein digestion/assimilation capacities, growth and survival. Four experimental diets were examined: C (control) I (supplemented with 750mg/kg soybean trypsin...

Expression and activities of pancreatic enzymes in developing sea bass larvae (Dicentrarchus labrax) in relation to intact and hydrolyzed dietary protein; involvement of cholecystokinin ArchiMer
Cahu, Chantal; Ronnestad, I; Grangier, V; Zambonino, Jose-luis.
In order to assess the influence of dietary protein on digestive enzyme expression and cholecystokinin (CCK) content in sea bass larvae, four groups of larvae were fed experimental diets from mouth opening until day 42: three isonitrogenous diets with increasing protein hydrolysate levels (0%, 14% and 46% of crude matter) and one diet incorporating starch. The groups fed high starch or high protein hydrolysate level exhibited the lowest growth. The final weight in these groups was 9.5 and 5.6 mg, respectively, whereas it reached approximately 20.0 mg in the groups fed 0% or 14% protein hydrolysate level. The highest levels of trypsin secretion were observed in larvae fed the lowest protein hydrolysate level. Paradoxically, the groups fed diet containing...

Protein hydrolysates from yeast and pig blood as alternative raw materials in microdiets for gilthead sea bream (Sparus aurata) larvae ArchiMer
Gisbert, Enric; Skalli, Ali; Fernandez, Ignacio; Kotzamanis, Yannis; Zambonino, Jose Luiz; Fabregat, Rogelio.
In this study, we have evaluated the incorporation of two types of protein hydrolysates at 9 and 12% levels of inclusion, one from yeast (Saccharomyces cerevisiae, YPH) and another one from pig blood (PBPH), in microdiets for gilthead sea bream (Sparus aurora) larvae, and compared these results to a microdiet containing fish protein hydrolysate and another group only fed with enriched live prey (rotifers and Artemia). The trial consisted in substituting up to 75% (wt/wt) the enriched Artemia with the experimental microdiets from 15 to 40 days post-hatch, whereas larvae were exclusively fed on microdiets from 40 to 55 dph. Protein hydrolysates used in the present study were obtained from different raw materials (yeast, pig blood and fish protein...

Substitution of live food by formulated diets in marine fish larvae ArchiMer
Cahu, Chantal; Zambonino, Jose-luis.
Until recently, it was considered impossible to feed newly hatched marine fish species with a compound diet. Substituting a compound diet for live prey was performed several weeks after hatching, depending on the species. Compound diets were well ingested at the early stage but larvae died with a gut full of food, suggesting that larvae were unable to digest the compound diet. The hypothesis was that younger larvae have insufficient digestive enzymes to thrive on compound diets, and that exogenous enzymes, provided from live prey, are necessary for early stages.The organogenesis of marine fish larvae is not completely achieved at hatching and histological studies have revealed that the anatomy of the digestive tract undergoes developmental changes over...
