To provide a comprehensive overview of natural antioxidant sources, their molecular mechanisms of action, and their viability as replacements for synthetic food additives.
Synthesized functional profiles of lipid- and water-soluble natural antioxidant classes, including vitamins, phenolic acids, diterpenes, flavonoids, and volatile oils.
Evaluated primary biochemical mechanisms of preservation, focusing on hydrogen atom donation, autoxidation chain breaking, and transition metal chelation.
Identified fat-soluble vitamin E and water-soluble vitamin C as effective, matrix-dependent inhibitors that disrupt autoxidation propagation.
Demonstrated that plant pigments like anthocyanins operate via dual modes of action by simultaneously chelating pro-oxidant metals and donating hydrogen to oxygen radicals.
Documented substantial radical-scavenging activity across botanical extracts, specifically tea catechins, grape proanthocyanidins, and herb-derived phenolic diterpenes.
