Description
Food 3D printing with plant-based ingredients uses extrusion of hydrocolloid‑reinforced protein or starch inks to create layer‑by‑layer structures.
Technical
The process relies on maintaining ink flowability at 80–120 °C while preserving protein structure, and inducing rapid ionic crosslinking (e.g., 100 mM CaCl₂) to gel the bioink within 30–60 s. The viscosity range of 200–500 mPa·s is critical for achieving 0.5 mm resolution, and fiber content must stay below 15 wt % to prevent nozzle clogging.
