Abstract
Disclosed is a method for separating and recovering soluble proteins from protein containing solutions employing foam fractionation. In the method, air is introduced as small bubbles into a pool of protein containing solution retained within a vessel, to develop a layer of foam above the liquid. The foam produced is confined within the vessel allowing the liquid to drain therefrom, the foam issuing from the vessel containing a higher concentration of protein than the original solution. The collected foam can be broken and rerun through additional stages of foaming to further concentrate the protein or process for recovery of the protein.
