Description
Foamification creates stable airy structures by emulsifying surfactants, while gelification forms semi-solid matrices through polysaccharide or protein cross‑linking.
Technical
Foamification relies on surfactants such as soy lecithin or whey protein isolate to lower interfacial tension, forming a film that traps air bubbles; the film stabilizes as interfacial molecules arrange into a viscoelastic shell. Gelification uses gellan gum or gelatin, which, upon heating and subsequent cooling, form a three‑dimensional network of polymer chains that immobilize water, yielding a semi‑solid gel.
