Production of Antioxidant Hydrolysate from Bovine Casein Using Immobilized Penicillium Aurantiogriseum Protease on Magnetic Nanoparticles

Peptides with bioactive properties can be released from the precursor proteins during food processing or digestion, and act as antioxidative compounds. Although, it has been proven that hydrolysate exerts higher antioxidant activity than purified peptides. The process of enzyme immobilization proved to be more practical and advantageous for catalysis than using free enzyme. The aim of this stud...

Purification and Identification of Antioxidant Peptides from Protein Hydrolysate of Scalloped Hammerhead (Sphyrna lewini) Cartilage

The aim of this study was to purify and identify peptides with antioxidant properties from protein hydrolysate of scalloped hammerhead (Sphyrna lewini) cartilage. Cartilaginous proteins of the scalloped hammerhead were extracted by guanidine hydrochloride, and three antioxidant peptides, named enzymolysis peptide of scalloped hammerhead cartilage A (SCPE-A), SCPE-B and SCPE-C, were subsequently...

Enzymatic grafting of peptides from casein hydrolysate to chitosan. Potential for value-added byproducts from food-processing wastes.

Tyrosinase was used to initiate the grafting of peptides onto the amine-containing polysaccharide chitosan. Chemical evidence for covalent grafting was obtained from electrospray mass spectrometry for products formed from reactions with glucosamine (the monomeric unit of chitosan) and the model dipeptide Tyr-Ala. When this model dipeptide was incubated with tyrosinase and chitosan, there was a ...
