Utilization of Avocado Seeds as Bioplastic Films Filler Chitosan and Ethylene Glycol Plasticizer

摘要

The purpose of this study is to determine the effect of ethylene glycol plasticizer on bioplastic characteristics including density, tensile strength, elongation at break, modulus of elasticity, scanning electron microscope, rapid visco analysis and functional groups. The bioplastic film was made from avocado starch filler chitosan using casting method of dissolving chitosan and starch solution with certain variations into hotplate magnetic stirrer and variation of ethylene glycol 5, 10, 15, 20 and 25 % w. Bioplastic characteristics were obtained by bioplastic density 203 g/cm~3 tensile strength 30.213 MPa, elongation at break 5.370 %, modulus of elasticity 2031.326 MPa, temperature of bioplastic gelatinization 91.55 °C.
