On Demand Production of Whey Protein Isolates (WPI) have always been hampered by the creation of pro-cream. This occurs as a byproduct during the microfiltration step to remove the remaining cream in Whey Protein Concentrate to achieve 90% WPI. However, new advancements in WPI processing equipment alongside research conducted at the Wisconsin Center for Dairy Research, has helped increase value, awareness and applications for the use of Whey Protein Phospholipid Concentrate (WPPC).
