Studies in recent years have detailed the antioxidant abilities of peptides obtained from plant proteins. These plant proteins serve as a novel origin for such peptides. They help conserve energy, aid in managing diseases linked to oxidation, slow food oxidation, and boost overall quality of life.
Reports on preparing, structuring, and assessing antioxidant peptides have grown, with some reaching commercial stages. However, a full review and assessment of those from plant proteins remains absent. This summary covers recent progress, including enzymatic hydrolysis for preparation, purification, identification, and uses, plus factors affecting, methods to evaluate, and mechanisms of antioxidant protein hydrolysates or peptides.
Traditional ways to purify and identify these peptides cost much and take long. Researchers use computer-based models like molecular docking and QSAR studies, bioinformatics tools, and updated protein databases to address this. Future efforts should target mass commercial output, detailed structure-activity links, deeper mechanism insights, and in vivo health benefit proofs.
Antioxidant peptides consist of protein pieces with antioxidant effects. Those from plant proteins are termed plant protein-derived antioxidant peptides. As demand rises for proteins high in nutrition and function, attention turns from usual animal proteins to plant ones.
Natural antioxidant peptides from plants draw global interest for being eco-friendly, sustainable, cheap, and free of toxic effects.
Peptides' ability to block oxidative stress and food oxidation draws evaluation of their capacity. Three approaches exist: chemical tests, in vitro cell biology methods, and in vivo animal tests.
Mechanisms include direct removal of reactive oxygen species, binding metal ions, stopping lipid peroxidation, and boosting the body's antioxidant defenses.
Proteins undergo hydrolysis with animal, plant, or microbial proteases to create hydrolysates. Further steps involve purification, membrane separation, electrophoresis, and chromatography such as gel permeation chromatography GPC , ion exchange chromatography IEC , and reversed-phase high-performance liquid chromatography RP-HPLC to isolate antioxidant peptides.
Peptides get identified via mass spectrometry or mass spectrometry/mass spectrometry, with activities checked in vitro and in vivo. Main preparation routes are chemical extraction, fermentation, synthesis, and enzymolysis.
Protein enzymolysis yields a mix of unhydrolyzed proteins, varied peptides by length, hydrophobicity, charge, and free amino acids. Accurate structure and activity checks require proper purification.
Key technologies feature chromatography GPC, IEC, RP-HPLC , membrane separation, or combinations. Protein hydrolysate identification relies on mass spectrometry, mass spectrometry/mass spectrometry, and bioinformatics techniques.
