Method of recovering glycoproteins and/or proteins derived from edible birds’s nest

Abstract

The present invention discloses a method of recovering glycoproteins and/or proteins from edible bird’s nest (EBN) of AerodramusandCollocaliaspp, which comprises the steps of preparing a crude extract of the edible bird’s nest and recovering glycoproteins and/or proteins contained in the crude extract by way of an aqueous two-phase system. The step of recovering glycoproteins and/or proteins includes: mixing the crude extract of edible bird’s nest in an aqueous two-phase system comprising a solvent, organic and/or inorganic salt and water; agitating the phase system; subjecting the phase system to separation in order to form separate phases containing glycoproteins and/or proteins; and recovering the EBN glycoproteins and/or proteins from the medium
