| 摘 要： | Solution properties of 7S globulins （7S）, 11S globulins （11S） and soy protein isolates （SPI） in dimethylsulfoxide （DMSO）/urea solvent system were studied by intrinsic viscosity and particle size distributions. The results showed that the existence of urea was the main reason for the denaturation and solubility of soy protein in the system, and the effects were more obvious with increasing of urea concentration in solutions. Suitably dissolution temperature and time contributed to the solubility of soy proteins.
