Nanocomposites were prepared by blending soy protein isolate with different percentage of MMT by melt extrusion technique. The nanocomposites were characterized by using, XRD, TEM, SEM and TGA methods. The XRD studies indicated the absence of diffraction peaks for the bio-nanocomposites. From the TEM studies it was ascertained that the degree of exfoliation increased with increase in MMT content. The morphology of the nanocomposites was ascertained from the SEM studies. The degradation pattern of the nano-composites was evaluated from the TG analysis. The drug delivery system of the nanocmposites was investigated by blending the nanocomposites with ofloxacin at different pH media. The various kinetic parameters were evaluated and the mechanism of drug delivery has been postulated based on the kinetic data.
