Plant-derived antioxidants: Biosynthesis, refining and applications.

Plant-derived antioxidants (PDAs) are promising alternatives to synthetic antioxidants, with review coverage of advances in their classification, biosynthesis, extraction, and functional applications.

• Why it matters: Their health and food uses are constrained by low natural abundance, complex impurities, poor stability, and contamination or deterioration during isolation.
• What they did: This review synthesizes recent progress on PDAs’ sources, antioxidation mechanisms, biosynthesis and regulation, plus extraction and refining, and summarizes applications as food additives and biomedicines.
• The result: It outlines how integrating synthetic biology, green purification, and nano-delivery may address industrial challenges and support precise design and versatile use in healthcare and food industries.
