The invention is directed to adhesives derived from animal or plant proteins, particularly canola and spent hen proteins. The adhesives are prepared by extracting the proteins by pH shifting; and either treating the extracted proteins with urea or sodium dodecyl sulfate, or polymerizing the proteins to form a protein-polymer conjugate. The invention is also directed to a wood based product comprising pieces of wood based material joined or consolidated with the adhesives.

Adhesives derived from agricultural proteins

The invention is directed to methods for extracting phosvitin from egg yolk involving contacting the egg yolk or egg yolk protein granules with a solution having a salt concentration of about 10% to form a mixture; optionally, heating the mixture; adjusting the pH of the mixture to separate phosvitin from other proteins; recovering the phosvitin. The phosvitin extract may be dephosphorylated and hydrolyzed to produce phosvitin phosphopeptides.

Methods of phosvitin extraction and phosphopeptide preparation from egg yolk

Described herein are methods of identifying and releasing bioactive peptides from ovotransferrin The method involves (a) contacting ovotransferrin with a reducing agent, a sonication step, a high pressure processing step, a heating step, a fermentation step, or any combination thereof, and (b) contacting the ovotransferrin after step (a) with a hydrolytic enzyme to produce bioactive peptides that exhibit angiotensin converting enzyme inhibitory activity or antioxidant activity when compared to the parent protein. The bioactive peptides may be added to foodstuffs, a medication, or to any potable, ingestible, or edible compositions.

Peptides that inhibit angiotensin converting enzyme and peptides with antioxidant activity purified from ovotransferrin and methods of producing and using the same

The instant invention relates to peptides obtained from the enzymatic hydrolysis of yellow pea seed proteins that are capable of lowering the blood pressure and reducing the effects of kidney disease in a subject by inhibiting or reducing the affinity of the enzymes in the renin-angiotensin system for their substrates, specifically renin, to compositions comprising said peptides and to uses thereof.
