Abstract
A novel squid chitin formed material is disclosed. Squid chitin is prepared by pulverizing squid crust and treating the pulverized chitin with caustic soda and then with hydrochloric acid to remove proteins and ashes. Squid chitin formed material such as sheet or fiber is then prepared by a freeze-defrost treatment. The squid chitin sheet and fiber have better physical properties than conventional crab chitin formed materials in terms of strength and folding endurance.
