Method for preparing high relative molecular mass chitin and chitosan, and comprehensive utilization
A process for preparing the chitin or chitosan with high relative molecular mass is characterized by that EDTA instead of HCl is used for decalficiation, resulting in no damage to molecular chain andhigher yield increased by 10% or more. Its by-products and rejected substance are all recovered for l...

Summary: | A process for preparing the chitin or chitosan with high relative molecular mass is characterized by that EDTA instead of HCl is used for decalficiation, resulting in no damage to molecular chain andhigher yield increased by 10% or more. Its by-products and rejected substance are all recovered for lower cost. |
