Abstract This review summarizes the major advances that have occurred over the last 5 years in the use of plant-based colloidal particles for the stabilization of oil-in-water and water-in-oil emulsions. We consider the characteristics of polysaccharide-based particles, protein-based particles and organic crystals (flavonoids) with respect to their particle size, degree of aggregation, anisotropy, hydrophobicity and electrical charge. Specific effects of processing on particle functionality are identified. Special emphasis is directed towards the issue of correctly defining the stabilization mechanism to distinguish those cases where the particles are acting as genuine Pickering stabilizers, through direct monolayer adsorption at the liquid–liquid interface, from those cases where the particles are predominantly behaving as ‘structuring agents’ between droplets without necessarily adsorbing at the interface, for example, in many so-called high internal phase Pickering emulsions. Finally, we consider the outlook for future research activity in the field of Pickering emulsions for food applications.

• Water-in-oil emulsions stabilized by surfactants, biopolymers and/or particles: a review (2020, background): “Due to the hydrophilic nature of the cellulose molecules, the fibrils, microfibrils and nanocrystalline cellulose are better wetted by water than oil, and therefore tend to stabilize water-continuous emulsions (Du Le, Loveday, Singh, & Sarkar, 2020).”
