Increasing consumer demand for higher quality, cheaper, more convenient, and healthier
emulsion-based products means that the food industry must have a good understanding of
the relationship between the structural and functional properties of food emulsions. This
review article provides an overview of the relationship between the composition and
structural organization of oil-in-water emulsions and their physicochemical (optical, rheological,
and stability) and sensory (appearance, texture, flavor, and mouthfeel) properties. It
also discusses recent advances in the design of structured emulsions with novel functional
properties, such as multiple emulsions, filled-hydrogel particles, multilayer emulsions,
microclusters, and air-filled emulsions
