Creating edible films using zein or rice protein through solvent evaporation or hydrogen bonding.
Origin: Mesoamerican (corn) and East Asian (rice) (ancient) — Mesoamerica and East Asia
See full technique reference →Zein dissolves in 70–80 % ethanol, forming a polymeric matrix that solidifies upon ethanol evaporation. Rice protein isolates form films by establishing extensive hydrogen‑bonding networks in an aqueous medium, often assisted by plasticizers such as glycerol.
