The interfacial properties of lipid droplets are crucial for infant digestion, yet few studies have explored the impact of the layers of lipid droplets on infant digestion. In this study, four emulsions were prepared: one with milk polar lipids (MPL) serving as the monolayer interface of the lipid droplet (ME-PL), one with MPL and membrane-specific protein (MSP) as the co-monolayer interface of the lipid droplet (ME-Co), one with liposome featuring MPL as the bilayer interface of the lipid droplet (BE-PL), and one with proteoliposome containing...
