Tilapia (Oreochromis niloticus) skin collagen hydrolysates (TSCHs) were obtained using Alcalase, Trypsin, and Protamex. Our results indicated that enzyme type, degree of hydrolysis, molecular weight distribution significantly affected the zinc-binding capacity TSCHs. Five peptides isolated purified via immobilized metal affinity chromatography reversed-phase high performance liquid chromatograp...

Experimental studies of fish cutting waste—scales and skin were carried out, their general biochemical composition was studied, a high content collagen established, elastin noted, which accounted for 76–86% the protein mass. Processes hydrolysis secondary raw materials have been developed: scales skin. Technological schemes developed influence conditions thermal, enzymatic, enzymatic-thermal, e...

Enzymatic hydrolysis of food proteins is convenient method to improve their functional properties and physiological activity. Herein, the successful covalent attachment alcalase on alginate micron submicron beads using carbodiimide based chemistry reaction subsequent application for egg white soy were studied. In addition electrostatic extrusion technique (EE) previously used by others, potenti...

Bile acids are involved in the modulation of various metabolic processes facilitating biliary excretion endogenous and exogenous cholesterol. The objective this study was to determine glycocholic acid binding capacity (BC) chicken blood hydrolysates using an optimized RP-HPLC methodology. Samples were hydrolysed a combination five different enzymes. Alcalase Protamex presented highest BC, with ...

Poultry by-products and rainbow trout (Onchorhynchus mykiss) viscera are abundant and underutilized resources that can be used as a unique protein source to make protein hydrolysates. In this study protein hydrolysate were made from these two different sources with Alcalase 2.4L. The functional properties of Fish viscera protein hydrolysate (FPH) compared to poultry by-products protein hydrolys...
