EXTRAÇÃO DE QUITINA, SÍNTESE E CARACTERIZAÇÃO DE QUITOSANA OBTIDA ATRAVÉS DE RESÍDUOS DE CAMARÃO (Macrobrachium amazonicum)

Abstract: RESUMO -A quitosana é um polímero natural, biocompatível, biodegradável, e atóxico. É derivada do processo de desacetilação da quitina, a qual constitui a maior parte do exoesqueleto dos insetos, crustáceos e parede celular de fungos. Depois da celulose, é o composto orgânico mais encontrado na natureza. A quitina foi separada dos outros componentes dos resíduos de camarão (Macrobrachium amazonicum) por um processo químico que envolve 3 etapas: desmineralização, desproteinização, e despigmentação. A quitosana … Show more

“…Chemical and microwave approaches were used to obtain chitin and chitosan from Pacific whiteleg shrimp, Litopenaeusvannamei garbage. The study found that a particle size of 32 mesh and six 5-min pulses were successful in deacetylation with a degree of 92 percent and a chitosan yield of 52.2 percent [102][103][104]. According to Elieh-Ali-Komi et al [69], the exoskeleton of crustaceans posses varying degrees of chitin, protein, calcium carbonate, phosphate, lipid and ash; however, the proportion of these parameters differ with species (Table 1).…”

“…In Brazil, shrimp trade has a strong social-economic impact, and its processing generates large amounts of waste (ALMEIDA et al, 2015). After being peeled and having their heads removed, shrimps lose approximately 47% of their total weight.…”
