What You Need to Know
Protein molecules unfold at moderate temperatures, forming interfacial films that trap air. Polysaccharides such as carrageenan or agar gelatinize to reinforce the network, while additives like soy lecithin lower surface tension. The balance of temperature, whipping time, and additive concentration determines foam stability and set time.
