What You Need to Know
Sesame seed phospholipids (lecithin) and minor proteins act as natural surfactants, forming an interfacial film when acidic water is slowly incorporated. The acidic environment protonates the phospholipids, enhancing their emulsifying ability, while gentle whisking provides shear to disperse oil droplets. Maintaining temperature below ~40 °C preserves the integrity of these emulsifiers, preventing coalescence.
