DL-o-Tyrosine is a hydroxylation product of phenylalanine.1 It is formed from phenylalanine by hydroxyl radicals generated during radiolysis and can be further hydroxylated to form 2,3-dihydroxyphenylalanine (2,3-DOPA). DL-o-Tyrosine has been used as a marker of irradiation processing in poultry meat.2
