Extraction and characterization of chitosan from shrimp shell waste using two different sequence method

Crustacean species such as shrimps are global production that has been reported to generate tons of waste annually that could affect the environment in terms of odour and aesthetic damage. Chitin can be derived into chitosan through deacetylation. Chitosan offers more potential in industrial applica...

Chitin can be derived into chitosan through deacetylation. Chitosan offers more potential in industrial application compares to chitin.

In spite of that, the quality of P2 chitosan was low in terms of DDA, solubility and ash content, which were 76.47%, 37.79% and 2.67%, respectively.
