    Obtenção e avaliação de concentrados proteicos de corvina (Micropogonias furnieri) processados por extração química
    (2009) Fontana, Aline; Centenaro, Graciela Salete; Palezi, Simone Canabarro; Prentice-Hernández, Carlos
    The objective of this study was to obtain and evaluate physicochemical and functional properties of protein concentrates from Micropogonias furnieri produced by pH shifting process, using alkaline and acid solubilization followed by isoelectric precipitation of muscle proteins. The concentrates showed high protein content and the maxim solubility for the minced (96.5%), for the alkaline (97.5%) and acid (93.7%) extraction was obtained at pH 11.0. The water holding capacity of the alkaline concentrate resulted in a value same or superior to water holding capacity of the acid concentrate in all investigated values of pH. The oil holding capacity of alkaline and acid concentrates showed no significant difference between the studied processes.

    Efeito da concentração de enzima e de substrato no grau de hidrólise e nas propriedades funcionais de hidrolisados proteicos de corvina (Micropogonias furnieri)
    (2009) Centenaro, Graciela Salete; Prentice-Hernández, Carlos; Salas-Mellado, Myriam de las Mercedes
    The objective of this work was to obtain hydrolysates with different degrees of hydrolysis using Alcalase 2.4L® and to evaluate the effect of the enzyme [E] and substrate [S] concentration on the functional properties of the hydrolysates. It was obtained hydrolysates with hydrolysis degree values ranging from 12.2 to 43.7%. The values of solubility and water holding capacity were similar for the greater number of the hydrolysates with minimum values in the pH 5.0. The hydrolysis degree showed direct relationship with the solubility and indirect with the water holding capacity, oil holding capacity, emulsifying capacity and foaming capacity.
