Abstract
A process is disclosed for the recovery of albumin in very high purity from human blood plasma by treatment of the blood plasma with polyethylene glycol (PEG) to precipitate out impurities followed by thermocoagulation of a resulting supernatant aqueous solution containing PEG and albumin in the presence of caprylic acid and isolation of the purified albumin by precipitation.
