What You Need to Know
Whipping introduces air into a protein dispersion, causing the proteins to unfold and form a viscoelastic film around bubbles. Emulsifiers such as lecithin or carrageenan lower surface tension, while sugars increase continuous phase viscosity, both enhancing foam stability. Maintaining temperatures below 40 °C preserves protein structure and prevents collapse.
