Multiple response optimization of heat shock process for separation of bovine serum albumin from plasma

Bovine serum albumin produced by heat shock from bovine plasma has been researched for the effects of sodium caprylate concentration [Cap], temperature (T), and pH on yield (Yield%) and purity (BSA%). Response surface methodology and desirability function approaches were applied to optimize its process. The best compromise solution was found with BSA% = 95.0 and Yield% = 28.5 for a [Cap] = 2 mM, T = 67.9°C, and pH = 5. A Monte Carlo simulation showed that it is possible to obtain excellent values for each individual response. However, a techno-economic feasibility study must be carried out to determine which one is the best option.
