Implication

Experimental study demonstrates reversible thermal control of emulsion foam stability using saponin nanofibrils, indicating potential for smart food and personal care products.

Key Points

Investigate the fabrication and stabilization mechanisms of smart, thermoresponsive oil-in-water emulsion foams using self-assembled glycyrrhizic acid nanofibrils.
Aerated and homogenized sunflower oil and glycyrrhizic acid nanofibril mixtures at elevated temperatures.
Rapidly cooled the continuous phase to induce glycyrrhizic acid fibrillar hydrogel self-assembly and droplet jamming.
Assessed thermal responsiveness and light-induced destabilization by incorporating ultraviolet-absorbing carbon black particles.
Bulk fibrillar hydrogel formation provided high storage modulus and yield stress, completely halting liquid drainage and substantially slowing bubble coarsening.
Reversible gel-sol phase transitions enabled rapid, on-demand foam collapse by increasing temperature.
Photothermal energy conversion via carbon black particles enabled photoresponsive switching from stable to unstable foam states under ultraviolet light.
