Description
A hydrocolloid foam leveraging kappa carrageenan’s calcium reactivity to create stable dairy-based structures.
Technical
Kappa carrageenan forms helical structures that crosslink via calcium ions, creating a heat-reversible gel. In foams, it stabilizes air bubbles by increasing interfacial viscosity while providing elastic rebound.
Culinary Significance
Used for dairy foams that hold shape without weeping, ideal for plated desserts or savory applications where a creamy yet structured texture is desired.
