Description
Alginate encapsulation uses calcium-induced gelation to create semi-permeable spheres that control flavor release.
Technical
Sodium alginate forms a gel matrix when exposed to calcium ions through ionotropic gelation, creating a cross-linked polymer network that can encapsulate liquids or solids while allowing controlled diffusion.
Culinary Significance
Enables precise flavor bursts, texture contrasts, and innovative presentations like liquid-filled spheres or encapsulated sauces.
