Effects of Polyol-Based Surfactants and Processing Conditions on the Microstructure and Rheological Properties of Emulsions
To investigate the effects of polyol-based surfactant types and processing conditions on the structure and physicochemical properties of emulsions, various emulsions were prepared using different surfactants and systematically evaluated. In addition, processing methods incorporating primary emulsification at elevated temperature followed by quenching and secondary emulsification were applied to compare the resulting microstructure and stability. Despite having identical compositions, either O/W or W/O emulsions were formed depending on the hydrophilic–lipophilic characteristics of the surfactants. Microscopic observations revealed that emulsions prepared by primary emulsification alone exhibited heterogeneous internal structures, whereas those subjected to quenching followed by secondary emulsification showed more uniform dispersion and improved structural stability. These differences in internal structure significantly affected viscosity and hysteresis behavior, with the secondary emulsification process leading to higher viscosity and more stable rheological properties. Furthermore, formulations prepared with sucrose- and sorbitan-based surfactants exhibited superior phase stability compared to those containing glycerol- and xylose-based surfactants. The crystallinity of the surfactants was also found to play a crucial role in determining the viscosity and textural properties of the emulsions.
