This experiment will be abandoned shrimp head shell as raw material, using the ultrasonic assisted EDTA method heads the chitin was extracted from the chitin acetylated macromolecule polymer, chitosan, and carries on the deacelation degree and antioxidant ability tests, due to its dissolution liquid film, the advantages of safe, non-toxic side effects, therefore, we applied to the production of natural chitosan film, and compared with different contents of chitosan natural chitosan film, performance evaluation, provide theoretical basis for the further development of chitosan membrane. At the same time, its water-retaining and fresh-keeping functions on tofu were tested, which made exploration and practice for the application of natural degradable chitosan extract in more aspects, and provided reference significance for the production of chitosan preservative film.
