constitute an advantage versus other β-1,4-linked polysaccharides (e.g., cellulose and chitin). Above the pKa, amino groups of chitosan become deprotonated, triggering polymer precipitation. Due to these properties and its ability to interact with a variety of molecules, chitosan has a number of commercial applications in the areas of bioadhesives (Dudhani and Kosaraju, 2010), waste treatment (Crini, 2005), food preservatives (Shahidi et al., 2002), food additives (Shahidi et al., 1999), pharmaceuticals (Paños et al., 2008), nutraceuticals (Chen and Subirade, 2005), and cosmetics (Boucher and Brunet, 2005).
