Soy protein isolate (SPI) was mixed with 10, 20, 30, and 40 wt% of corn cob by solvent casting method. The SPI/corn cob biocomposite films were tested for tensile, morphological, thermal, and enzymatic biodegradation properties. The result demonstrated that, as corn cob content increases, the tensile strength, modulus of elasticity, and thermal stability of biocomposite films increased, but elongation at break and enzymatic biodegradability decreased. Nevertheless, the treated SPI/corn cob biocomposite films with acrylic acid showed improvement in tensile strength, elongation at break, modulus of elasticity, thermal properties, and resistance to biodegradability by enzyme over the untreated SPI/corn cob biocomposite films .
