- Abstract:
- Objective To isolate and purify Bletilla polysaccharide by ceramic membrane.Methods Taking the recovery rate of polysaccharide as the index，optimize the technological parameters of membrane separation of Bletilla polysaccharide，and determine the best separation process.Results The optimum conditions of ceramic membrane separation of polysaccharide were obtained by response surface analysis，namely temperature 47 ℃，material to liquid ratio 6 mg·mL-1，membrane pressure 2 bar.The recovery rate of polysaccharide was 78.44%.Conclusion Porcelain membrane can effectively improve the purity of polysaccharide and provide basic data for its further study.
