Effect mechanism of HSDE technology on solubility of SPI
SPI was treated with HSDE technology, then the effect mechanism to solubility of modified SPI were investigated. SDS-PAGE electrophoresis was preliminary proved that HSDE technology can improve the solubility of SPI in the water; HPLC made further efforts to proved that HSDE technology can improve the solubility of macromolecule proteins to SPI, and had low-impact on low molecular protein effect.
