Description
3‑D printed savory gels are protein‑based edible inks that form viscoelastic networks suitable for layer‑by‑layer fabrication.
Technical
Gelation occurs via heat‑induced protein unfolding and cross‑linking, often enhanced by microbial transglutaminase. The process requires precise temperature control to avoid denaturation and maintain viscosity for extrusion, resulting in a cohesive, springy matrix ideal for savory constructs.
