In the current study, biocompatible and biodegradable soy protein isolate (SPI) based film was developed by incorporating polar components using casting technique. The effects of additive components (glycerol, sorbitol and polyethylene glycol) with SPI were analyzed by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The result confirmed that the incorporation of polar components with soy protein isolate exhibits strong intermolecular interaction. This is the easiest method to develop biocompatible films that have wide applications in biomedical, biotechnology, food safety and food packaging industries.
