Abstract

Legumes are rich sources of protein and consider a good alternative to make a protein films. In this study, central composite design to investigate the simultaneously effect of the grasspea protein isolates (2 - 10 percent), glycerol (0.5 - 7%) and oleic acid (0 - 2%) on properties of edible films made from grasspea protein isolates, such as thickness, density, percentage of solubility in water, acid and alkaline, and permeability to water vapor and oxygen were used. The result shows that increasing protein and glycerol concentrations were significantly increased water vapor permeability and increasing in concentrations of oleic acid decreased it signifcantly. Solubility in water and acid by increasing the protein content decreased and with increasing glycerol and oleic acid increased (P
