| Abstract | ||
| Chitin's low degradability and insolubility in several common solvents limit its use in food systems. Therefore, it was deacetylated to produce chitosan, a multifunctional biopolymer. Mushrooms are macro fungi that contain a large amounts of chitin. this study successed in chitin extracted from Phellinus igniarius and Coriolopsis trogii (basidomycetes fungi type) and its yield were 15.43 and 11.37%, this chitin was convert to chitosan by the process of deacetylation with yield were 24.73 and 22.51% respectively. Characterization of chitosan by Fourier Transform Infrared Spectroscopy (FT-IR), where the bands associated with the stretching and vibration of O-H, N-H, and CO bonds were apparent in the FTIR patterns. Scanning Electron Microscopy (SEM) images appered validated the chitosan's purity.
