    Author: Ren DW, Wang YL, Bao DC, Xie WY, Ma XJ.
    Journal: Guang Pu Xue Yu Guang Pu Fen Xi; 2006 Oct; 26(10):1825-8. PubMed ID: 17205730.
    Abstract:
    Chitosan blend membranes were prepared by casting the mixture solution of highly deacetylated chitosan (HDC) and moderately deacetylated chitosan (MDC). FTIR was used to investigate the components of the blend membranes before and after lysozymic degradation. It was found that the ratio of MDC in the blen d membranes had a linear relation with the degree of deacetylation (DD) of the membranes. In enzymatic degradation process, DD of the membranes exhibited an increasing tendency. The FTIR data indicate that MDC component in the blend membranes can be removed by selective enzymatic degradation. This also suggests that FTIR can be used as an efficient and rapid method to investigate the degradation process of chitosan.
