Acceptable low-phenylalanine foods and beverages can be made with glycomacropeptide from cheese whey for individuals with PKU.
Glycomacropeptide (GMP) is a whey protein that contains no aromatic amino acids including phenylalanine (phe). The objective of this study was to make a variety of palatable, low-phe foods and beverages with GMP and to assess their acceptability by conducting consumer sensory studies in individuals with PKU. Results demonstrate acceptability of products made with GMP. GMP supplemented with limiting indispensable amino acids could provide an alternative protein source for individuals with PKU.
