Whey Protein Phospholipid Concentrate (WPPC), a low-value coproduct, is currently being examined as a source of nutritional and functional ingredients. WPPC contains high-value components, such as various types of proteins and phospholipids.
What is WPPC? When we make cheese, whey protein isolate (WPI) can be produced from the whey stream. WPI needs to have a fat content of less than 1% so, in addition to traditional fat separation technologies, WPI undergoes microfiltration to remove fat. The retentate in this microfiltration process is WPPC, which is also known as procream. WPPC is a high-fat, high-protein product (see table).
