## Abstract **Summary:** A simple spectrophotometric method is proposed for determining deacetylation degrees (__DD__) of chitinous materials using phosphoric acid as the UV‐transparent solvent system. Calibrating by the extinction coefficients (__A__~210~) of D‐glucosamine and __N__‐acetyl‐D‐gluco
