Extraction of chitosan from shrimp shells
Webyield of chitosan from shrimp shells was about 34%. Moreover, in the present study obtained yields of chitosanis higher than the reported methods, this could be explained by the nature of environment and divergence in shrimp species and also method of extraction. Other hand, 34% of total chitosan yield was recorded with crab shell waste. WebChitin was recovered through enzymatic deproteinization of the shrimp processing by-products. Different microbial and fish viscera proteases were tested for their deproteinization efficiency. ... these two crude proteases were used separately for chitin extraction and then chitosan preparation by N-deacetylation. Chitin and chitosan samples ...
