Chitin is isolated from crab and shrimp shells as follows: (1) Ca2CO3 in the shell flakes is dissolved out by treatment with dilute HCl (demineralization), (2) astaxanthin pigments and lipids are extracted with organic solvents, e.g., acetone and ethanol, (decolorization), and (3) proteins are extracted with NaOH or digested enzymatically by proteases or microorganisms (deproteinization). Chitin is obtained as residue in the form of flakes.
