Abstract: |
|||
| The present invention discloses a method for extracting several chitinous elements by using chitin as raw material and various biological products prepared by using obtained several chitinous elements according to different proportion. Those biological products can be extensively used in the fields of food, medicine, tobacco, paper-making, textile and chemical industries. Said invention is characterized by soaking raw material in several inorganic solutions instead of organic solvent, through degradation and separation so as to obtain several products and by-products. It possesses the advantages of simple method, high product purity and low cost, etc. | |||
