What You Need to Know
The process relies on amphiphilic molecules such as phospholipids and saponins to reduce interfacial tension between oil and water. Heating the oil to 60–70 °C dissolves the fat, and gradual whisking into the aqueous base forms fine droplets that are stabilized by the emulsifiers. Precise temperature control and sufficient mechanical shear are critical to prevent phase separation.
