Description
Creating edible films using zein or rice protein through solvent evaporation or hydrogen bonding.
Technical
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.
