Whey Protein Isolate Cross-Flow Microfiltration (CFM) is an instantized whey protein isolate extracted from sweet dairy whey. Proprietary membrane techniques are used to yield a highly pure, nutritionally superior and undenatured isolate. Whey Protein Isolate CFM goes through an instantizing process that allows it to disperse easily in beverages and solutions. Its low flavor profile, high protein content, and low lactose and fat levels make it the protein of choice for many beverage applications.
