Owing to their good solubility and film-forming properties, phenolic acid-<i>g</i>-chitosan derivatives can be used for preservation of fruits and vegetables. However, the chemical synthesis used for the preparation of these derivatives poses a great challenge to food safety. In this study, a method involving horseradish peroxidase catalysis was used to prepare a gallic acid-<i>g</i>-chitosan derivative. The grafting mechanism was studied. Then, the derivative's ability to scavenge free radicals
