Taking Procambarus clarkii head shell as raw material, the chitin is extracted using EDTA method. On the basis of single factor test, the best conditions were deselected by orthogonal test. The results show that when the reaction temperature is 30 ℃, pH 12, the use of 13% EDTA solution as extraction solvent feed ratio of 1:15, reaction time 25min, the best extraction, the extraction rate is 24.05%, before and after reaction decalcification and removal of protein rates is 100%and 98.6%, respectively.
