In view of this fact that there are few researches on the application of ultra-high pressure micro-fluidization in the modification of protein, and that the in-depth studies on the functional property changes are still lacking both at home and abroad, this paper focuses on the modification of soy protein isolate treated by high pressure microfluidization. This paper offers a new approach to protein modification as well as a new method on the application of dynamic high pressure microfluidization,...
