| Abstract: | One-factor-at-a-time method and response surface methodology were used to optimize the microwave-assisted extraction of highly deacetylated chitosan from Chirocephalus diaphanous eggshell.The optimal extraction conditions for achieving maximum degree of deacetylation of chitosan were as follows: microwave treatment time 33.4 min,ethanol soaking time 86 min,NaOH concentration 57.27%.Under these conditions,chitosan with a degree of deacetylation of 84.12% was obtained from Chirocephalus diaphanous eggshell. |

| Keywords: | chitosan Chirocephalus diaphanous response surface methodology microwave degree of deacetylation |
