Abstract
|
|
|
|
Chitin was prepared from Solenocera prominentis by deproteinization pretreatment of Neutrase. The optimal enzyme concentration of neutrase, pH, and temperature on deproteinization were 3.0 mg/ml, pH 6.0 and 50C as indicated by the minimum protein remaining on the chitin. The residual protein, the degree of deacetylation, Ca and P content in chitin prepared from Solenocera prominentis were similar with commercial chitin. The molecular weight was 1.2 X 10& dalton and the yield of chitin was 25.8%.
