ABSTRACT
The soy hull polysaccharide (SHP) exhibits excellent interfacial activity and holds potential as an emulsifier for emulsions. To reveal the behavior of SHP at the water/oil (W/O) interface in situ, molecular dynamics (MD) simulations and particle tracking microrheology were used in this study. The results of MD reveal that SHP molecular spontaneously move toward the interface and rhamnogalacturonan-I initiates this movement, while its galacturonic acids on it act as anchors to immobilize the SHP molecules at the W/O interface. Microrheology results suggest that SHP forms microgels at the W/O interface, with the lattices of the microgels continually undergoing dynamic changes. At low concentrations of SHP and short interfacial formation time, the network of the microgels is weak and dominated by viscous properties. However, when SHP reaches 0.75 % and the interfacial formation time is about 60 min, the microgels show perfect elasticity, which is beneficial for stabilizing emulsions.
