Determination of the Deacetylation Degree of Chitooligosaccharides

Determination of the Deacetylation Degree of Chitooligosaccharides

The methods for determination of chitosan content recommended in the Chinese Pharmacopoeia and the European Pharmacopoeia are not applicable for evaluation of the extent of deacetylation (deacetylation degree, DD) in chitooligosaccharides (COS). This study explores two different methods for assessme...
