| As a potent antioxidant, vitamin E mitigates lipid peroxidation and preserves muscle structural integrity, thereby enhancing color stability, improving tenderness, and prolonging shelf life. This review summarizes the mechanisms by which vitamin E regulates antioxidant enzyme activity and modulates key signaling pathways, including Nrf2/Keap1, MAPK, and PI3K/Akt. It also examines the synergistic effects of vitamin E with other natural antioxidants, such as vitamin C, selenium, and polyphenolic compounds, in improving beef quality. The potential of vitamin E to enhance bovine physiological performance, immune function, and meat quality is also discussed. Future research directions are proposed, focusing on optimizing supplementation strategies, elucidating breed-specific responses to vitamin E, and exploring its roles in gut health and sustainable cattle production systems. It can provide reference for promoting the sustainable development of the beef industry. |
