The radiation-induced degradation mechanism of chitosan in the aqueous HjOj solution is more complicated than that in solid state. Besides the reactions in solid state, the primary reactions might occur as follows (reactions (31.11) through (31.14)) ...

Radiation-induced main-chain degradation renders polysaccharides soluble, or at least increases their solubility, and therefore technical interests have focused on the radiation-induced main-chain degradation of certain biopolymers, such as cellulose, chitin and chitosan [96,104-107]. In being the main component of plants, cellulose is a widespread biopolymer. In technical processes, high-energy radiation treatment is applied to increase the solubility and to alleviate the hydrolysis of the constituent cellulose of plant-based raw materials. The G-values of the main radiolysis products, as reported by Ershov,...
