Chitosan is actually a substance taken from chitin, a polysaccharide that's found in the exoskeletons of crustaceans. It is processed out by removing the shells from shellfish like shrimp, lobster, and crabs. Currently, chitosan and its derivatives have practical applications in the form of solutions, suspensions, particles, e.g. beads, resins, spheres, nanoparticles and sponges, gels/hydrogels, foams, membranes and films, fibers, microscopic threads, and scaffolds in many fields: medicine and biomedicine, pharmacy, cosmetology, hygiene and personal care, food industry and nutrition, agriculture and agrochemistry, textile and paper industries, edible film industry and packaging, biotechnology, chemistry, and catalysis, chromatography, beverage industry and enology, photography and other emerging fields such as nutraceuticals, functional textiles and cosmeto- textiles, cosmeceuticals, nanotechnology, and aquaculture
