Whey Protein isolate: a multifunctional dairy-derived biomaterial


Douglas, Timothy (Lancaster University )


Whey protein isolate (WPI) is an inexpensive byproduct from the dairy industry which can be processed into autoclavable hydrogels with high compressive strength which support the adhesion, growth and differentiation of cells which can be applied in bone regeneration. Furthermore, WPI hydrogels can solubulized hydrophobic molecules and hence serve as a delivery vehicule for hydrophobic molecules with biological activity (e.g. antibacterial agents.) WPI can also be processed into flibrillar coatings for biomaterials, which also support the adhesion, growth and differentiation of cells. This presentation will review the aforementioned applications of WPI.
