Polysaccharide processing crosses into both chemical and hygienic processing domains, depending on its end product. Across both product markets, polysaccharides can be organically extracted from natural sources or synthesized in a reaction process. Starting with base materials, polysaccharides are often prepared via extraction, separation, and purification steps. Within these steps, specific unit operations being performed include mixing, blending, sizing, sorting, stripping, drying, heating, cooling, and certain targeted chemical reactions.
