Example from our pipeline: Separation of whey proteins into high grade alpha-lactalbumin and a beta-lactoglobulin enriched WPI.
Our alpha-lactalbumin product (Lane 2) is highly enriched and practically devoid of low molecular weight compounds, carbohydrates, lipids and most of the other whey proteins. The remaining non-alpha protein bands are primarily beta-lactoglobulin which may be further removed in a subsequent polishing step, if need be.
By virtue of the non-destructive processing method, the isolated alpha-lactalbumin is substantially native. In addition to this conservation of functionality, the method offers very high yields, which is witnessed by the only slight amount of alpha-lactalbumin present in the enriched beta-lactoglobulin product, see lane 3 of the SDS PAGE pictured.
The beta-lactoglobulin fraction is a highly functional food protein ingredient. The immunoglobulins and lactoferrin present may be isolated as individual proteins in a subsequent polishing step.
