ABSTRACT
Objective To study the optimum decoloration technological conditions of crude polysaccharides from Cordyceps militaris Link. (PCM) by macroporous resin. Methods With the decolorization rate and retention rate of PCM as indexes, static adsorption factor experiment was used for the optimization of seven kinds of macroporous resin. And then the optimum conditions of decolorization of PCM were investigated by the static/dynamaic adsorption single-factor experiments. Results D941 macroporous resin is the best. The optimum decoloration technological conditions were as followsinitial concentration of the sample was 50 mg/mL, pH value was 5.5, operating temperature was 45℃, the flow rate of dynamaic adsorption was 2.5 BV/h, and the sample solution volume was 5 bed volume per hour. Under the optimal conditions, decolorization rate and retention rate of PCM were ( 93.9 ± 3.4) % and (91.7 ± 2.2) %, respectively. Conclusion The resin D941 is suitable for the decoloration of PCM. The optimized method is feasible and reliable, having the prospects for popularizing.
