Abstract:

Electrospinning of soy protein isolate(SPI) in the presence of poly(vinyl alcohol)(PVA) was investigated in order to broaden applications of SPI. The effect of properties of SPI/PVA solutions and the glycerol addition on the morphology of electrospun fibers were discussed. Characterization and mechanical properties of electrospun SPI/PVA membranes were also analyzed. The results show that introduction of glyce-rol can improve the electrospinability of SPI/PVA. The tensile strength of electrospun SPI/PVA membranes decrease from (5.17±0.62) MPa to (1.67±0.21) MPa and the elongation show an increase tendency with increasing the amount of glycerol.
