A soluble polycationic agent (Disperfloc C-500) was used for whey clar
ification. Turbidity was decreased by more than 90% with the addition
of only 0.8 g/l of the agent, at pHs ranging from 7.3 and 7.6 and with
a temperature step of 5 min at 50 degrees C. The calcium and phosphat
e content of whey was decreased by more than 50% while 98% of the tota
l protein content still remained soluble.
