With prolonging the ultrafine grinding processing time, the solubility, ing and emulsifying properties of SPI powders were improved, the content ofα-helix, β-sheet and random coils increased, while β-turn decreased. Furthermore, the ultrafine grinding time clearly influenced the volatile compounds of SPI powders.

The majority of ultrafine grinding processes are, therefore, conducted at high solid contents in the range 60–80% solids. However, the rheological properties of slurries in ultrafine grinding are more complex and need further studies to appreciate its behaviour. In practice, it is found that the slurry viscosity does not change significantly ...

Furthermore, the ultrafine grinding treatment for 6 h did not change the α-helix and random coil compositions of SPI. Above the results, the ultrafine grinding time could alter the secondary structure of SPI. It suggested that the blended effect of intense shear and heat produced during ultrafine milling transformed the protein conformations.
