After cellulose, chitin is the most prevalent natural polymer. It can be found in the exoskeletons of insects, plankton, fungi, and crustaceans. The biochemical method of extracting chitin from crustacean shells is a sophisticated and novel process that yields the long chain carbohydrate polymer chitin. It involves two important phases that are essential for the removal of protein, calcium carbonate, and other minerals found in the shells. Qualitative tests give confirmatory tests for presence of carbohydrates. In order to take a confirmatory test of derived chitin, qualitative and phytochemical tests of chitin were conducted. Even though chitosan is thought to be safe and environmentally benign, the harsh chemicals used to produce it from chitin must be handled cautiously to prevent harm to the environment.
