Abstract

To study the optimum deproteination conditions of polysaccharide from corn silk with cetyl trimethyl ammonium bromide(CTAB). The removal rate of protein and residual rate of polysaccharide was chosen as the index. The optimal deproteination condition of CTAB was that NaCl was 0.010g, pH was 6.0, the volume ratio of CTAB was 10%, dissociated time was 24h. Deproteinization rate was 58.17%, the residual rate of polysaccharide was 25.29%.
