Production and quality control of chitin and chitosan from shrimp (Farfantepenaeus notialis) shells obtained from Hendijan, Iran by sequence process

Abstract

Aim: The study aims to evaluate and quality control chitin and chitosan of Rubian pink shrimp (F. notialis) shell in Iran. Methods: The solubility, moisture content, and degree of deacetylation (DD), pH, yield %, moisture and ash of chitosan were examined. The results showed that 3% HCI and 4% sodium hydroxide were suitable concentration for demineralization and deproteinization, respectively at ambient temperature (20±2 oC). Results: The study's outcome is expected yield%, moisture content and DD% of chitosan and chitin was 30.85% and40% 3.33% and 6.33% and 47% and 45% respectively. Chitosan high solubility obtained by deacetylation with 50% sodium hydroxide for 16 h at 60 °C. Conclusion: The present study showed F. notialis can be a source to produce chitin and chitosan for food industries.
