A comparative study on protein separation using different techniques

Concentration of commercial soy milk into protein stream using crossflow filtration unit with ultrafiltration membrane and conventional method was examined. Two membranes of molecular weight cut off (MWCO) of 10 and 50 kilo Dalton (kDa) of regenerated polysulfone material were used to determine the...
