Analysis Note
The degree of acetylation may be determined by dye binding7 or titration methods8.
Preparation Note
Prepared by the alkaline deacetylation of chitin obtained from the shells of shrimp (Pandalus borealis). Chitin is manufactured industrially by crushing shrimp shells, then washing the solids with acids to remove inorganic and proteinaceous material. The purified chitin is deacetylated to chitosan by treatment with a strong base such as sodium hydroxide. The resulting chitosan may be further purified by preparation of solutions in acid followed by neutralization and precipitation.
Quality
May contain foreign matter.
Application
Forms gels with multivalent anions. Gives clear solutions that dry to strong, clear films.
