Abstract
Soy meal a coproduct of the soy oilbased biodiesel industry has up to 50 protein content The main aim of this work was to develop valueadded application for soy meal Soy meal was plasticized by glycerol and water denatured by the addition of guanidine hydrochloride GHCl and then blended with poly butylene adipatecoterephthalate PBAT petroleum based tough biodegradable polymer Characterization by FTIR spectroscopy confirmed that soy meal was plasticized and denatured The blends of PBAT/soy meal SM PBAT/plasticized soy meal and PBAT/GHCl modified plasticized soy meal mPSM were fabricated by industry prevalent extrusion and injection molding process The developed bioblends were characterized by thermal and mechanical testing One of the important outcomes of this research was that elongation of the bioblend was found to increase by 80 after plasticization and denaturation of soy meal Scanning electron microscope analysis showed that PBAT/mPSM blends have smoother surfaces and better internal structures than the other twoAuthors are thankful to the Ontario Ministry of Agriculture Food and Rural Affairs OMAFRA2009 New Directions Alternative Renewable Fuels ‘‘Plus’’ Research ProgramSR9223 and the Hannam Soybean Utilization Fund HSUF for their financial support
