This work aimed to illustrate the correlation between the dynamic adsorption process of ultrasound-assisted cross-linked MP on the oil-water interface and the stability of the fabricated emulsion. The interfacial pressure, adsorption kinetic coefficient, dynamic rheological properties of crosslinked MP (E-MP5), sonication before MP crosslinking (E-UMP5), and sonication after MP crosslinking (E-MPU5) and the corresponding emulsion properties, adsorbed proteins, microrheological properties, and multiple light scattering were determined. The results showed that the emulsion properties were positively correlated with the interfacial properties of MP. Ultrasound treatment could more effectively improve the interfacial properties and emulsion stability of the MP molecules than the Native treatment. Among the ultrasonic groups, the E-MPU5 group exhibited the highest interfacial pressure (15.81 mN/m), diffusion rate (K_diff), penetration rate (K_P), rearrangement rate (K_R), dilatational modulus, elastic modulus, and E-π slope (2.65). Correspondingly, based on the change of K_diff, K_P, and K_R, E-MPU5-fabricated emulsion had the lowest droplet size (1.56 μm), the maximum adsorbed protein content (93.08%), and the highest absolute zeta potential value. Additionally, the decreased viscosity, elastic index, macroscopic viscosity index, and turbiscan stability index in the E-MPU5-fabricated emulsion indicated the formation of a more stable emulsion. Therefore, this work suggests that sonication after crosslinking could greatly improve the interfacial adsorption behavior of MP, and the improvement of interfacial properties is conducive to the enhancement of emulsion stability.

本工作旨在阐明超声辅助交联MP在油水界面上的动态吸附过程与制备的乳液稳定性之间的相关性。交联MP（E-MP5）的界面压力、吸附动力学系数、动态流变性能​​、MP交联前超声处理（E-UMP5）、MP交联后超声处理（E-MPU5）以及相应的乳液性能、吸附蛋白质、微流变性能性质和多重光散射被确定。结果表明，乳液性能与MP的界面性能呈正相关。超声波处理可以更有效地改善界面性能和MP分子乳液的稳定性优于Native处理。在超声组中，E-MPU5组表现出最高的界面压力（15.81 mN/m）、扩散速率（K _diff）、穿透速率（K _P）、重排速率（K _R）、膨胀模量、弹性模量和E-π 斜率 (2.65)。_{相应地，基于K diff}、K _P和K _R的变化，E-MPU5制备的乳液具有最小的液滴尺寸（1.56μm）、最大的吸附蛋白含量（93.08％）和最高的绝对zeta电位值。此外，E-MPU5制造的乳液中粘度、弹性指数、宏观粘度指数和turbiscan稳定性指数的降低表明形成了更稳定的乳液。因此，本工作表明，交联后进行超声处理可以大大改善MP的界面吸附行为，界面性能的改善有利于乳液稳定性的增强。
