초록

The physicochemical properties of fungal chitosan at 95$^{\circ}C$ and 40$^{\circ}C$ acid treatment was as follows respectively. The nitrogen content was 6.71%, 6.91%, the viscosity 2.23cps, 2.21cps, the acetylation 12.0%, 12.7% and the molecular weight 3.12${\times}$10$\^$5/ Dalton, 3.01${\times}$10$\^$5/ Dalton. The absorbency band of reference, FCs-40 and FCs-95 in I.R. spectra was almost in accord with one another. In solid state NMR spectra, methyl group(-CH$_3$) was observed lightly. That means which deacetylation was well occurred. Carbonyl group(C=O) was not observed. C$_1$ to C$\_$6/ in solid state NMR was well observed seperately enough.
