Description
Protein-stabilized foam using gelatin for thermal resilience.
Technical
Hydrolyzed collagen proteins form helical structures that trap air bubbles within a viscoelastic matrix, resisting collapse at elevated temperatures through partial renaturation.
Culinary Significance
Creates stable foams that maintain structure in warm applications unlike traditional whipped cream.
