What You Need to Know
The process relies on oil‑water emulsions stabilized with food‑grade surfactants such as Tween 80 or lecithin to keep volatile flavor compounds dispersed. Rheology is tuned to 5–50 mPa·s at 25 °C to ensure smooth extrusion through 0.5–1.0 mm nozzles while maintaining shape fidelity. Thermal control between 60–80 °C melts binders without degrading heat‑labile aromatics, and post‑printing curing times of 30 s–5 min prevent crystallization or chocolate setting issues.
