Application
L-phenylalanine is a nutritional supplement and one of the essential amino acids. There are almost no limiting amino acids in the protein of most foods. Can be added to baked foods, in addition to strengthening phenylalanine, it reacts with sugars to form an amino carbonyl group, which can improve the flavor of food. It can also be used for preparing amino acid infusion and comprehensive amino acid preparations.
