- *Abstract
-
The sugars in soy-flourare separated from protein and oxidized to multifunctionalcrosslinking agents, primarily aldehydes and carboxylic acids. The oxidized sugars are then reacted with theprotein, thus eliminating the need for external crosslinkers. The resulting crosslinked resin exhibitsenhanced thermal and mechanical properties and higher stability (resistance) inwater. This green and low cost method tocrosslink proteins will be useful in making inexpensive bio-based materialswith improved strength (Young’s modulus, stress-strain) and stability.
The technology can be easily extended to flours from other grains wherethe two components are protein and carbohydrates in the form of sugars and/orlow molecular weight starches. This soy-flour basedresin may also be used with natural or synthetic fibers to form composites withhigher mechanical, physical and thermal properties for many applications.
