Abstract

The polysaccharide chitin (CHIT), extracted mainly from exoskeletons of crustaceans, can be obtained from shrimp fishery waste. It is the source of an important biopolymer, chitosan (CHITS) that presents a wide range of applications, such as the treatment of effluents containing heavy metals and dyes, and in several bioremediation processes. In this context, this work evaluated the chitosan production from two shrimp residues, the whole cephalothorax (CPTx) and the carapace (CRP, the exoskeleton from the cephalothorax), of the commercially exploited shrimp Xiphopenaeus kroyeri, to identify which of the two sources is more advantageous. Starting from standard masses of CPTx and CRP residues, the production of 3.12 times more CHITS from CRP, compared to CPTx, is demonstrated. The results are extremely important since both residues were submitted to the same physicochemical processes, requiring the same chemical reagents. Therefore, there is a significant reduction in the quantity of reagents when extracting CHITS from CRP, representing a great economic and environmental advantage. (AU)
