Size Reduction. Size reduction can be accomplished in a variety of ways, based on the specific polysaccharide structure, such as thermal hydrolysis, chemical hydrolysis (acidic, alkaline, ozonolytic, and free radical), sonication and homogenization, by leading to a random size reduction often resulting in an increase in sample polydispersity.
