Ultrasound-powered bovine bone protein hydrolysate-flaxseed gum emulsions: modulation of stability, interfacial properties, and curcumin bioaccessibility

, forming a compact interfacial film that enhanced stability. After 25 days of storage, the 750 W-treated emulsions exhibited the lowest peroxide value (9.24 mg/L) and TBARS (1.25 mg/L), as well as the highest curcumin encapsulation efficiency (82.1 %) and bioaccessibility (71.37 %). This study demonstrates that moderate ultrasound power facilitates the molecular rearrangement and synergistic interaction of BBPH and FG, thereby enhancing emulsion functionality and providing a promising strategy for developing polysaccharide-based delivery systems.
