| titleOfInvention | Method for preparing chitosan by taking crude chitin as raw material |
| abstract | The invention provides a method for preparing chitosan by taking crude chitin as a raw material, which comprises the following steps: performing decolorization pretreatment on the crude chitin by using a mixed solution of formic acid and hydrogen peroxide; and performing deacetylation reaction on the crude chitin subjected to the decolorization pretreatment. The method can decolorize chitin raw materials more quickly and efficiently and can prepare chitosan products with significantly lower protein content. |
