Description
Edible ink printing for flavor layering deposits oil‑soluble aromatics within sugar or chocolate matrices using controlled emulsion chemistry and precise thermal management.
Technical
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.
