In our project we have studied the varying regulation activities of plasmin and lipase in bovine milk, under treatment condition from 40MPa to 900Mpa, different temperature, time, and pressure exerting' ways. Within pressure treatments at 40MPa to 80MPa, the activities of plasmin and lipase were increasing. However, there was pressure treatment no significant effect (P>0.05) on increasing activities. Under treatment condition from 500MPa to 900MPa, activities of both enzymes were completely inac...
