Patent No. EP3917338 (titled "Native Whey Protein For Improving Intestinal Maturation") was filed by Nutricia on Feb 3, 2020. The application was issued on May 21, 2025.
Native whey protein fraction for improving intestinal maturation and reducing intestinal permeability in infants, particularly preterm infants. The protein is obtained through a process involving microfiltration of defatted milk, followed by fractionation and demineralization of the lactose stream. The resulting native whey protein is characterized by high nativity and low alkaline phosphatase activity, making it suitable for inclusion in infant formulas.
