Chitin solutions and purification of chitin
WebThe yield of chitin recovered (as average) in relation to the initial pens was 37.0 4.1% (w/w). Reports about chitin extraction from squid pen are relatively scarce, and to the best of our knowledge, the present study is the first to extract chitin from L. opalescens species. WebAbstract. Nowadays, chitin and chitosan are produced from the shells of crabs and shrimps, and bone plate of squid in laboratory to industrial scale. Production of chitosan involved deproteinization, demineralization, and deacetylation. The characteristics of chitin and chitosan mainly depend on production processes and conditions.
