Over the past decade, Pickering emulsions (PEs) stabilized by protein particles have been the focus of researches. The characteristics of protein particles at the oil-water interface are crucial for stabilizing PEs. The unique adsorption behaviors of protein particles and various modification methods enable oil-water interface to exhibit controllable regulation strategies. However, from the perspective of the interface, studies on the regulation of PEs by the adsorption behaviors of protein particles at oil-water interface are limited. Therefore, this review provides an in-depth study on oil-water interfacial adsorption of protein particles and their regulation on PEs. Specifically, the formation of interfacial layer and effects of their interfacial characteristics on PEs stabilized by protein particles are elaborated. Particularly, complicated behaviors, including adsorption, arrangement and deformation of protein particles at the oil-water interface are the premise of affecting the formation of interfacial layer. Moreover, the particle size, surface charge, shape and wettability greatly affect interfacial adsorption behaviors of protein particles. Importantly, stabilities of protein particles-based PEs also depend on properties of interfacial layers, including interfacial layer thickness and interfacial rheology. This review provides useful insights for the development of PEs stabilized by protein particles based on interfacial design.
在过去的十年中，由蛋白质颗粒稳定的 Pickering 乳液（PEs）一直是研究的焦点。蛋白质颗粒在油水界面的特性对于稳定 PEs 至关重要。蛋白质颗粒独特的吸附行为和各种修饰方法使油水界面能够展现出可控的调节策略。然而，从界面的角度来看，关于蛋白质颗粒在油水界面的吸附行为对 PEs 的调节的研究还很有限。因此，本综述深入研究了蛋白质颗粒在油水界面的吸附行为及其对 PEs 的调节作用。具体来说，阐述了界面层的形成以及其界面特性对由蛋白质颗粒稳定的 PEs 的影响。特别是，蛋白质颗粒在油水界面的吸附、排列和变形等复杂行为是影响界面层形成的前提。此外，蛋白质颗粒的粒径、表面电荷、形状和润湿性等对其界面吸附行为有很大影响。重要的是，基于蛋白质颗粒的 PEs 的稳定性也取决于界面层的性质，包括界面层厚度和界面流变学。本综述为基于界面设计的蛋白质颗粒稳定的 PEs 的发展提供了有用的见解。
