Natural biofilms are increasingly interested in replacing plastic films with serious long-term environmental consequences. This study aimed to investigate the role of Xanthan Gum (XG), Carboxymethyl Cellulose (CMC) and Gum Arabic (GA) on biofilm properties. Membrane preparations (by weight % of the mixture) with 2 % lablab or lima bean powder, 7 % rice flour, the ratio of XG, CMC, GA was 0.15 %, respectively; 0.3 %; 0.45 %. The viscosity of the film-forming solution was determined using a Brookfield DV III Ultra viscometer. The mechanical properties of the films were measured using a Brookfield CT3 instrument. The results showed that the polysaccharides had a significant effect on the properties of the formed film but did not significantly affect the deformation of the film. With the same ratio and type of polysaccharide, the viscosity of the film-forming solution from lima bean powder (LiBP) tended to be higher than that of lablab bean powder (LaBP). GA did not form an efficient film compared with XG and CMC. The biofilms were made from LiBP with 0.3 % XG and 0.3% CMC, and LaBP with 0.45 % CMC had mechanical properties higher than other mixing ratios. Research is promising when applied to producing edible biofilms used in the packaging of low-moisture foods, contributing to a sustainable and environmentally friendly food system.
