| Abstract: | The idible film was produced by adding glycerol (GLY) and with the soy protein isolate as main raw material in this paper. The influence of the medium and method of film-forming on the film function was studied and the function of edible film was compared in acidic and alkaline conditions. The optimal film-forming process parameter was found to be 2:1 for protein to glycerin ratio and pH3 and substrate concentration 8% at 80℃ in acidic condition, and 3:1 for protein to glycerin ratio and pH10 and substrate concentration 10% at 90℃ in alkaline condition. |
