The functionalization of chitosan managed to obtain a method that benefits from a good property in terms of the object of a prepared material with better characteristics. In the study of the data, regarding the low molecular weight chitosan, it is necessary to provide the oxidation of chitosan in the presence of hydrogen peroxide and its functionalization with natural antioxidants – quercetin by the method of grafting, a study of antioxidant properties compared to a compound commonly used to graft industrial chitosan with chitin as well as to graft oxidized chitosan with the same flavonoid. It has been established that the decrease in the molecular weight of chitosan favored grafting may have a concentration, and the result may be composed in order to be able to have a higher antioxidant concentration. |
