Degrees of chitosan deacetylation from white shrimp shell waste as dental biomaterials

---

Background: Chitosan is biomaterial improved for various dentistry applications because it is biocompatible. degradable. non¬toxic, and not carcinogenic. The main parameter affecting the characteristics of chitosan is deacetylation degree. Purpose: This study is aimed to determine the degree of deacetvlated of chitosan derivedfrom white shrimp shell waste used as dental biomaterial.
Methods: White shrimp shells were crushed into powder. Next. deproteination process was conducted with 3.5% NaOH solution. demineralized with IN HCI solution, and then depigmented with 90% acetone solution into chitin powder. Deacetylation process was then. conducted by soaking the chitin powder in 50% NaOH solution for 6 h at 65°C to produce white powder of chitosan. Aflenvards. deacetylation degree test was conducted by using Fourier Transform Infrared Spectrophotometer (FTIR) to calculate the ratio of the absorptian bands between the absorbance peak of amide group about 1655 cm-1 and the absorbance peak of hydroxyl group about 3450 cm-1
Results: The result of the deacetylation degree test on the chitosan powder derived from white shrimp shell waste was high, about 85.165%, and had the eligible form, solubilitv and pH. Conclusion: It can be concluded that the deacetylation degree of chitosanfrom white shrimp shells could reach 85.165%.
Key words: Chitosan, shrimp shell waste, deacetylation degree
