The present invention describes a method of marking fruits which comprises an incision in a fruit piece surface with a laser beam and the deposition in such superficial incision of a contrast agent comprising salts or oxides of iron or copper at a concentration between 0.001% and 1 % of the total weight. This salts or oxides are capable of reacting with any of the phenolic and/or polyphenolic compounds present in the superficial tissues of the fruit. This contrast agent may also comprise other additives: acidity regulators, emulsifiers, antioxidants and complexing.
