Studies on Extraction Technique of Chitin from the Pupa of Dictyoploca Japonica and Quality Test of Product

Abstract:

In order to produce high-quality chitin, the extraction of chitin from pupa of Dictyoploca japonica was studied by acid-alkali method. The extraction technique of chitin from the pupa was as the follows: Pupa skin were dipped in 4%HCl for 20h in 35°C , then in 6%NaOH for 4h in 85°C, followed by decoloring in 10% H₂O₂ for 0.5h under 85°C. Under this conditions, the produced chitin was white flaky solid with 6.5%-9.5% water content, 0.65%-0.97% ash content and 5.78%-6.67% nitrogen content, the productivity of the processing was 28%. Its quality indexes reached that of edible chitin.
