Abstract: The invention provides a process for the separation of pea protein. The process begins with an aqueous extract or solution of pea protein, which is passed through at least one expanded bed absorption (EBA) process. The EBA process comprises contacting the aqueous extract or solution of pea protein with at least one adsorbent resin, said adsorbent resin comprising at least one ligand (L1 or L2), having particular chemical structures. Proteins of interest are isolated by eluting them from said adsorbent resin. The invention also provides various protein compositions obtainable via the method of the invention.

Abstract: The invention provides a process for the separation of soy protein. The process begins with an aqueous extract or solution of soy protein, which is passed through at least one expanded bed absorption (EBA) process. The EBA process comprises contacting the aqueous extract or solution of soy protein with at least one adsorbent resin, said adsorbent resin comprising at least one ligand (L1 or L2), having particular chemical structures. Proteins of interest (e.g. trypsin inhibitor (TI) protein or beta-conglycinin) are isolated by eluting them from said adsorbent resin. The invention also provides various novel protein compositions obtainable via the method of the invention.

Abstract: The present invention relates to the large-scale fractionation and isolation of peptides, polypeptides and protein(s) from a potato derived protein solution such as potato extract, potato fruit juice and fruit water using an adsorbent coupled with a ligand for the capture of the protein(s), from the protein solution. In particular the invention relates to a process for the isolation and separation of patatin and potato protease inhibitors using a low temperature non-denaturing process.
