摘要: Enzymatic hydrolysis of sardine viscera by three broad spectrum proteases was investigated using the pHstat method (24 h, pH 8, 50 °C). After hydrolysis, fractions (sludge, aqueous phase and oily phase) were collected. For each fraction, lipids phospholipids quantified molecular weights peptides determined. Under these conditions, degree (DH) varied from 1.9% (Flavourzyme), 3.1% (Protamex) to 3.3% (Alcalase). Dry matter distribution indicated that all performed increased solubilisation proteins: protein recovery for ranged 57.4% 61.2%. Furthermore, total lipid content in liquid parts (oily phases) (at least 85% raw material are which may improve commercial applications. In addition, richer than those extracted classical chemical extraction, especially after Alcalase hydrolysis.
