MAIDI-TOF–MS of seven hydrosoluble colored fractions. Gly–Glc P1-1, Gly–Glc P1-2, Gly–Glc P2-1 and Gly–Glc P2-2 represent the fractions eluted using C18 separation from the melanoidins (glycine/glucose model), respectively; Pro–Glc P1-1 and Pro–Glc P1-2 represent the fractions eluted using C18 separation from the mela-noidins (proline/glucose model), respectively; Phe–Glc P1-1 represents the fraction eluted using C18 separation from the melanoidins (phenylalanine/glucose model).
