Oxidative Destruction of Chitosan and Its Stability

The properties of chitosan degraded under hydrogen peroxide action is studied. Using FTIR spectroscopy, HPLC, and 13 C NMR spectroscopy, it is found that the oxidative destruction of chitosan is accompanied by the crosslinking reactions leading to formation of the insoluble fraction of polymer. The...

Description
Summary:The properties of chitosan degraded under hydrogen peroxide action is studied. Using FTIR spectroscopy, HPLC, and 13 C NMR spectroscopy, it is found that the oxidative destruction of chitosan is accompanied by the crosslinking reactions leading to formation of the insoluble fraction of polymer. The mechanism of the crosslinking process and production of chitosan capable of maintaining solubility for a long time are discussed.
