ABSTRACT:In this study, pullulanase was debranched in different amylose content starch and normal corn starch, and amylose with different chain length was separated by centrifugation. At the same time, the mechanical properties and application properties of the materials were studied. The higher the amylose content, the higher the tensile strength of the plasticized starch, the lower the water absorption after plasticization, and the better the water resistance; this study limited the plasticizer to be biocompatible. Degradation of glycerol in the body. The high linear content of plasticized starch is a new material with broad application prospects. Thermoplastic starch has hygroscopicity, but its mechanical properties are lower than other thermoplastic polymers. In this study, wood starch fiber modified starch was added, and it was concluded that natural wood fiber is a good reinforcing fiber for plasticized starch.
