Abstract

Chitosans (20 and 100 cp, 2%) were irradiated in acetic acid solution (2%) with different doses (2-200 kGy) of Co-60 gamma rays to investigate the yields of chitosan oligomers. A rapid decrease of viscosity was observed up to 10 kGy and then the viscosity decrease slowed down gradually with increasing irradiation dose. Brown color developed heavily for irradiation dose over 100 kGy. Yields of chitosan dimer, trimer and tetramer were 3.6, 3.0 and 1.8%, respectively, at a dose of 100 kGy in 100 cp chitosan solution.
