Whey protein-based oxygen barrier

At this stage of the project, various samples of films have been produced: they consisted of whey protein-coated films and multilayer laminates composed of an intermediate layer of whey protein-coated on PET and then laminated with PE.

Results on the oxygen permeation properties of whey protein-coated plastic films met the initial goal and have confirmed that whey protein isolate coating solutions display very good oxygen barrier properties. Future work will focus on scaling up the results at lab and pilot scale in order to arrive at a commercially feasible technique for producing whey-coated plastic films.
