                                Chitin is the second most abundant polysaccharide on Earth, following cellulose, with an estimated billion tons produced annually. A good source of chitin is not limited to a single organism, but depends heavily on the intended application, considering factors like yield, purity, and sustainability, with leading options found in crustaceans, insects, and fungi.
