- ItemHidrolisado protéico de pescado obtido por vias química e enzimática a partir de corvina(2009) Martins, Vilásia Guimarães; Costa, Jorge Alberto Vieira; Prentice-Hernández, CarlosThe fish proteins has the advantage of a high sensibility to the hydrolysis and also a balanced composition in aminoacids. The production of protein hydrolyzed from by-products of fish process industry has been receiving more attention on the last years. The aim of this work was to evaluate the production of protein hydrolyzed from Micropogonias furnieri through chemical and enzymatic methods, verifying some functional properties. The results showed that the production of the hydrolyzed improved some functional properties of the proteins found in the filet and in the waste, what is desirable for a subsequent application.

- ItemEvaluation of functional properties in protein hydrolysates from bluewing searobin (prionotus punctatus) obtained with different microbial enzymes(2011) Santos, Sarita D’Avila dos; Martins, Vilásia Guimarães; Salas-Mellado, Myriam de las Mercedes; Prentice-Hernández, CarlosEnzymatic hydrolysis of proteins from low commercial value fish could be produced for uses like functional ingredients in a wide and always increasing zone of application in different food products. The objective of this work was to evaluate the functional properties and the amino acid profile of enzymatic hydrolysates from Bluewing searobin (Prionotus punctatus), using two microbial enzymes, Alcalase and Flavourzyme. The enzymatic hydrolysate obtained through the addition of the enzyme Alcalase reached the maximum solubility (42%) at pH 9, water holding capacity (WHC) of 2.4 gwater gprotein−1, 4.5 goil gprotein−1 of oil holding capacity (OHC) and an emulsifying activity index (EAI) of 54 m2 gsolids−1 at pH 3. On the other hand, the hydrolysate obtained from Flavourzyme attained 38% of solubility at pH 9, 3.7 gwater gprotein−1 and 5.5 goil gprotein−1 for the holding capacities, and an EAI of 71 m2 gsolids−1 at pH 11. The hydrolysate with Flavourzyme produced best results for WHC, OHC, and EAI because it had solubility lower than the hydrolysate of Alcalase. The hydrolysate produced by Alcalase had a higher amino acid content compared with Flavourzyme’s hydrolysate. However, both showed a good essential amino acid amounts. In general, these results indicate the potential utilization of the hydrolysate from Bluewing searobin in food formulations for the direct human consumption.
