Fish, chitin, and chitosan production 301

Table 6.7 Applications of chitin in its original or modified form

It appears that the production of chitin and chitosan from shrimp or
crustacean shells will yield several benefits to human and the environment.
Further research in this aspect is needed to develop more cost-effective
production methods, which should enhance the properties of chitin and chitosan
and broaden their uses and applications.
