Aside from the above applications, MF membranes have found dynamic use in major areas within the dairy industry, particularly for milk and whey processing. The MF membranes aid in the removal of bacteria and the associated spores from milk, by rejecting the harmful species from passing through. This is also a precursor for [[pasteurisation]], allowing for an extended shelf-life of the product. However, the most promising technique for MF membranes in this field pertains to the separation of casein from [[whey protein]]s (i.e. serum milk proteins).<ref>GEA Filtration – Dairy Applications. 2013,  GEA Filtration, accessed 26 September 2013, <http://www.geafiltration.com/applications/industrial_applications.asp.></ref>  This results in two product streams both of which are highly relied on by consumers; a [[casein]]-rich concentrate stream used for cheese making, and a whey/serum protein stream which is further processed (using [[ultrafiltration]]) to make whey protein concentrate. The whey protein stream undergoes further filtration to remove fat in order to achieve higher protein content in the final WPC (Whey Protein Concentrate) and WPI (Whey Protein Isolate) powders.
