Abstract: The invention is directed to precipitating whey lipids from a source material such as whey by adding a sufficient amount of chitosan to form a chitosan-lipid complex, and subsequently precipitating out the lipid from the resulting whey supernatant. The precipitate is removed either by filtration or centrifugation. The supernatant contains all the whey proteins which may then be recovered by conventional means such as ultrafiltration and spray drying. The lipids from the chitosan-lipid complex are then extracted

Abstract: Described are methods of removing phospholipids and other off-flavor-causing compounds from edible proteins using a cyclodextrin treatment. The methods include treating soy protein with cyclodextrins such as β-cyclodextrin to form cyclodextrin-compound complexes and then separating the resulting complexes from the protein. Optionally, prior to treating the protein with cyclodextrin, the protein is sonicated and then treated with a phospholipase, such as phospholipase A2. Versions of the methods described herein are capable of removing more than 99% of phospholipids from soy protein.

Abstract: Antifreeze polypeptides, antifreeze compositions including the polypeptides, nucleotides encoding the antifreeze polypeptides, methods of making antifreeze compositions, and methods of inhibiting ice crystal growth are provided herein. The peptides are based on the primary sequence of collagen and include those having a molecular weight between about 500-7000 Da. The peptides preferably include cationic polypeptides. The methods of making antifreeze compositions include digesting collagen or gelatin into hydrolysates with peptides having molecular weights between about 500-7000 Da. The digestions are performed with proteases and/or non-enzymatic hydrolysis. The methods of inhibiting ice crystal growth include adding the antifreeze polypeptides or compositions described herein to a composition to be frozen. The methods may be used to inhibit ice crystal growth in frozen food products.

Abstract: Disclosed is a hybrid protein-polysaccharide superabsorbent hydrogel. The hydrogel includes two interpenetrating matrices: a first matrix which is an acylated, cross-linked protein matrix, and a second matrix which is an anionic polysaccharidc matrix. The two matrices can be non-cross-linked, or the hydrogel can further include bridging moieties that covalently cross-linking the acylated, cross-linked protein matrix to the anionic polysaccharide matrix.
