Abstract
In this study, the suitability of mungbean protein as a raw material to produce biodegradable film was tested in comparison with soy protein. Protein from mungbean seed was extracted by acid precipitation at pH 4.5 using acetic acid. Protein content of the isolated mungbean protein was 81.93%. Films were prepared by dissolving either proteins of mungbean or soybean with water at pH 7.0 and casting onto a teflon plate. Effect of glycerol concentration on three physical properties of the film: tensile strength (TS), percentage elongation (% E) and water vapor permeability (WVP) were investigated. TS of films decreased with increasing glycerol concentration. In contrast, % E and WVP of films increased with increasing glycerol concentration. Mungbean protein can be used as a raw material to produce biodegradable film.
