The growth and development of the whey industry demonstrates the myriad of potential ingredients that can be developed and produced as separation technologies develop, such as ultrafiltration (UF), diafiltration (DF), and microfiltration (Novak and others 1992; Zydney 1998; Maubois 2002). These technologies are increasingly being applied to skim milk. From a small base in New Zealand and the European Union, a global business in MPCs and MPIs has now developed (Lagrange 2012).
