The invention relates to an anti-oxidation Chinese grass turtle egg protein peptide extract as well as a preparation method and application thereof, and belongs to the technical field of biological preparation. The invention relates to a Chinese grass turtle egg protein peptide extract, which comprises peptide fragments with amino acid sequences as shown in SEQ ID NO.1-6. The preparation method comprises the steps of separation, enzymolysis, purification and the like, and specifically comprises the following steps: separating out egg white, freeze-drying, preparing egg white crude protein peptide hydrolysate by using an ultrasonic-assisted enzymolysis method, and finally purifying, freezing and drying to obtain protein peptide powder. The Chinese grass turtle egg protein peptide extract is prepared by adopting an ultrasonic-assisted papain method, the obtained polypeptide is relatively high in purity and clear in main component and structure, the activity is well maintained, and the Chinese grass turtle egg protein peptide extract has the capabilities of removing ABTS free radicals, DPPH free radicals and hydroxyl free radicals and enhancing iron ion reduction, and has a remarkable antioxidant effect.

The invention discloses a preparation method of large yellow croaker egg protein iron ion chelated phosphopeptides. The preparation method comprises the following steps: preparing a large yellow croaker egg protein solution, adjusting pH and heating, performing specific enzymolysis and centrifugation, and freeze-drying to obtain phosphopeptides. The phosphopeptide component is directly prepared from the large yellow croaker egg protein by utilizing a one-step enzymolysis method, the hydrolysis degree of the prepared large yellow croaker egg protein phosphopeptide is 40.79-42.25%, the N / P molar ratio is 0.35-0.40, and the IC50 value is 0.04-0.06 mg / mL, the steps are simple, the operation is convenient, the phosphopeptide is effectively extracted from the large yellow croaker egg, and the preparation method has the advantages that the cost is low, and the application prospect is wide. The prepared phosphopeptide has the ferrous ion chelation capability which is obviously higher than that of casein phosphopeptide, and can be applied to the food industry as a novel nutritional supplement.
