Edible films were prepared using a combination of rice protein concentrate and the polysaccharide pullulan. The protein-pullulan mixture with up to 50% protein concentrate could be cast on a glass plate into films with tensile strength of about 18 MPa and water vapor permeability of 40 g × mil/m(^2) × day × mmHg. Film strength and water vapor resistance were improved by the addition of small amounts of propylene glycol alginate under alkaline condition. Oils were also incorporated into the film for improved water vapor resistance.
