Abstract:
This study developed a Pickering water-in-oil-in-water (W/O/W) emulsion (PWE) for co-delivering vitamins C and E using soy protein isolate (SPI) and pectin (PEC) particles as emulsifiers. Two particle types were synthesized via distinct nucleation mechanisms: (1) heat-treated SPI-PEC complexes formed at pH 4.0 and (2) SPI-PEC complexes formed through pH regulation followed by heating. Type 2 particles exhibited smaller sizes, more regular spherical structures, and stronger intermolecular interactions than type 1. Higher PEC concentrations further enhanced particle compactness. Additionally, type 2 particles demonstrated superior interfacial protein adsorption, forming stable and elastic interfacial membranes in the PWE. As a result, PWEs stabilized with type 2 particles achieved controlled release and high bioaccessibility of vitamins C (90.18 %) and E (85.24 %). These findings provide insights into the development of heat-induced biopolymer particles as effective PWE stabilizers.
