Locust bean gum (LBG)-based edible film was prepared, and opacity, water vapor permeability (WVP), tensile strength (TS) and elongation (E) of the film were measured. Opacity values of the film was a little higher than that of other transparent films. WVP decreased as LBG concentration decreased. Plasticizers and drying temperature didn't seem to influence WVP. WVP of the film increased greatly at 85% RH as compared to that of 0% RH. WVP of the film seemed to increase linearly with thickness of the film. But WVP of the film was lower those of other edible films. TS increased with increase of LBG concentration, and decreased with increase of glycerol concentration. E decreased with increase of LBG concentration, and increased with increase of sorbitol concentratin. LBG-based composite films were prepared by adding agarose, k-carrageenan or xanthan gum. TS and E of the composite film with addition of k-carrageenan increased.
