Currently valorization of fish discards by-products is becoming fundamental for the sustainable management fisheries and seafood transforming industries. Thus, we have studied changes in production chemical properties protein hydrolysates (FPH) oils from (heads (He) skins + bones (SB)) gurnard (Trigla spp.) captured at different seasons. Hydrolyses were performed by Alcalase (2.5 mL/kg by-produ...

The production of fish protein hydrolysate from underutilized species is attracting the industrial interest for increasing rich values. central composite design was used to optimize degree enzymatic hydrolysis freeze-dried (FPH) by application commercial Alcalase on recovery mixed small protein. effects time, temperature, pH and enzyme concentration (DH) five strains as Rastrelliger brachysoma ...

Process optimization is essential for the large-scale viability of food industry. Central composite rotational design (CCRD) followed by response surface analysis was used to optimize production fish protein hydrolysate (FHP). FHP obtained from tilapia filet trimmings hydrolyzed subjected using Alcalase 2.4L™, Neutrase™, and Novo-Pro™ D enzymes under temperature, enzyme concentration, pH-contro...

Collagen isolated from the ribbon jellyfish (Chrysaora sp.) was hydrolysed using three different proteases (i.e. trypsin, alcalase and Protamex) to obtain bioactive peptides. Angiotensin-I-converting enzyme (ACE) inhibitory activity and antioxidant activities (i.e. ferric reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity) of the peptides were...

BACKGROUND The main objective of this experiment was optimal use of none edible protein source to increase nutritional value of production with high biological function, including antioxidant activity. METHODS Sheep visceral (stomach and intestine) was used as substrate. Response surface methodology (RSM) was used to optimize hydrolysis conditions for preparing protein hydrolysate from the sh...

A simple and green approach was developed to produce a novel nanogel via self-assembly of modified soy protein and dextran, to efficiently deliver riboflavin. First, modified soy protein was prepared by heating denaturation at 60 °C for 30 min or Alcalase hydrolysis for 40 min. Second, modified soy protein was mixed with dextran and ultrasonicated for 70 min so as to assemble nanogels. The modi...
