  • Milk protein concentrate

    Processing. To make milk protein concentrate, whole milk is first separated into cream and skim milk.The skim milk is then fractionated using ultrafiltration to make a skim concentrate that is lactose reduced. This process separates milk components according to their molecular size. Milk then passes through a membrane that allows some of the lactose, minerals, and water to cross through.
