Despite the wide use of modified proteins as emulsifiers, enhancing the interfacial and antioxidant stability of algae oil emulsions remains challenging. This study explored the synergistic effects of (3-lactoglobulin ((3-Lg) modification via glycation, high-pressure microfluidization treatment (HPM) and (-)-epigallocatechin-3-gallate (EGCG) binding on the stability of algae oil emulsion. Results demonstrated that compared with (3-Lg-stabilized emulsion, those stabilized by synergistic modified (3-Lg (EHG48(3-Lg) exhibited a 6.4% increase in the interfacial layer thickness and a reduction in surface tension. After being stored at 4 degrees C for 90 days, the mean droplet size remained below 400 nm, and the emulsion retained stability under extreme conditions (90 degrees C, 300 mM NaCl, pH 6-10). Under accelerated storage at 37 degrees C for 12 days, the thiobarbituric acid reactive substances and peroxide value of EHG48(3-Lg-stabilized emulsions decreased by 4.0 and 0.4 mu g/mL, respectively, compared with the unmodified (3-Lg-stabilized emulsion. Conclusively, the synergistic modification of (3-Lg by glycation, HPM treatment and EGCG binding effectively enhanced the system stability and oxidative stability of algae oil emulsion compared with (3-Lg, G48(3-Lg and HG48(3-Lg-stabilized emulsions.
