Bioactive peptides as antioxidants and antimicrobials: fundamentals and applications

Abstract

Bioactive peptides are well-known for their remarkable tissue affinity, specificity, and effectiveness in promoting health. Extracted from food proteins, these bioactive peptides have displayed significant potential as functional foods and nutraceuticals. Throughout the years, numerous potential bioactive peptides derived from food sources have been documented. These bioactive peptides offer a wide range of crucial functions within the human body, including acting as antioxidants, antimicrobial agents, anti-inflammatory compounds, anti-hypertensive substances, and immunomodulators. More recently, extensive research has been conducted to investigate the origins, bioavailability, potential physiological effects and functionality, as well as the mechanisms of action of bioactive peptides in rendering health benefits. Researchers have also delved into various technological methods for preparing, purifying, and characterizing these peptides. This contribution primarily centers on exploring the antioxidant and antimicrobial aspects of bioactive peptides.
