Description
Emulsification techniques vary to achieve distinct textures in sauces and dressings.
Technical
Oil and water are combined by surfactants such as lecithin or egg yolk proteins, which lower interfacial tension and stabilize droplets. Droplet size is controlled by shear rate: gentle whisking yields 10–50 µm droplets, while high‑shear devices produce sub‑micron droplets that increase viscosity and creaminess. Acidic pH (4–5) protonates egg proteins, enhancing their emulsifying capacity and extending shelf life.
