Facile extraction of chitin and chitosan from shrimp shell

SpletIn this way chitin (10% DD) was deacetylated by the enzyme into chitosan with DD of 90%. The formic acid treatment reduced the molecular weight of the polymeric chain from 2x10(5) in chitin to 1.2 x 10(4) in the chitosan product. It is concluded that nearly complete enzymatic deacetylation has been demonstrated for low-molecular chitin.
