Description
Egg white proteins denature into a stable foam matrix reinforced by sugar's glass transition state.
Technical
Ovotransferrin and ovalbumin proteins unfold under mechanical stress (whipping), forming a viscoelastic network stabilized by sucrose disrupting water activity. Maillard reactions occur at syrup interface.
Culinary Significance
Creates ethereal, cloud-like textures for desserts while protecting delicate flavors from heat degradation.
