Pickering high internal phase emulsions (HIPEs) are normally highly concentrated emulsions stabilized by colloidal particles with a minimum internal phase volume fraction of 0.74. They have received considerable attentions in many fields, including pharmaceuticals, tissue engineering, foods, as well as personal care products. The aim of this perspective is to update the current knowledge on the field of protein-based Pickering HIPEs, emphasizing those aspects that need to be explored and clarified. Research progresses in constructing HIPEs by protein-type colloid particles as well as promising research trends in basic research and potential applications were highlighted. Promising researches in this field include: (1) To clarify bioavailability and evolution of activity of active ingredients in Pickering HIPEs by oral administration, (2) To construct Pickering interfacial catalysis platform using protein colloidal particles, and (3) To expand the emerging applications of Pickering HIPEs in fields, such as partially hydrogenated oils (PHOs) replacers, probiotics encapsulation as well as the template for porous materials.
