چکیده انگلیسی


• Chitosan was isolated from species of Indian white shrimp from the Persian Gulf.
• The microwave process had a more advantages over that of chemical method.
• The highest percent of chitosan preparation were achieved under the optimum conditions.
• The successful conversion of chitin to chitosan was confirmed with FTIR and XRD analysis.

Chitosan is a water soluble polysaccharide that was extracted from the wastes of Persian Gulf shrimp. It has been a big challenge for the scientists to find different biological, mechanical, physical, enzymatic and microbial procedures to extract edible chitosan. In this study chitosan (isolated from waste of species of Indian white shrimp) with high functionality was produced using mild conditions (temperature (60, 80 and 100 °C), concentration of alkaline (30, 40 and 50%) and time (90, 195, 300 min) of reaction in chemical method and power of microwave (300, 600 and 900 W), concentration of alkaline (30, 40 and 50%) and irradiation time (20, 100, 180 S) in microwave method) and short duration which did not degrade the structure of chitosan. It was observed that the highest percent of chitosan preparation (19.47%), degree of deacetylation (89.34%) and molecular weight (806,931 Da) were achieved in microwave style at 50% NaOH solution, 720 W microwave power and 20 S reaction time.
