Study on modification of soy protein isolate hot-pressed
The soy protein isolate(SPI) was hot-pressed directly, and was hot-pressed after modified with epoxy chloropropane, surface hydrosulfuryl content of SPI, surface hydrophobicity of SPI, molecule shape of SPI were studied. The results show that surface hydrosulfuryl content was decreased and surface hydrophobicity was increased, SPI globulin structure was destroyed.
